Lightning 9900 V Series Product Off e r i n g s

The Lightning 9900 V Series offers two models – the Lightning 9980V™and the
Lightning 9970V™. The Lightning 9980V system is recommended for users requiring large
storage capacities of 149TB+ of raw storage capacity. With the same advanced architecture
as the Lightning 9980V system, the Lightning 9970V system bridges the gap between
standard midrange and premium-priced advanced-function storage, with capacities up to
18TB+ of storage. The Lightning 9970V system is recommended for users who require
advanced function capabilities of premium storage, yet do not need the actual storage
capacity of the Lightning 9980V system. Table 1 compares key features of the two new
Lightning 9900 V Series product offerings.

Selecting the Lightning 9970V system or Lightning 9980V system depends on capacity
requirements, performance requirements, and expected growth of data. The Lightning 9900
V Series therefore offers product alternatives that cover a very broad range of scalability, as
illustrated in Figure 1.

An Overview of the Lightning 9900 V Series Arc h i t e c t u re

The Lightning 9900 V Series intelligent storage systems are the most powerful
enterprise systems in the industry today and two generations ahead of the competition. The
new architecture used in the Lightning 9900 V Series has almost twice the internal
processing power and bandwidth of our earlier enterprise systems. Figure 2 illustrates the
architecture of the Lightning 9900 V Series.

The Lightning 9980V
system has almost twice
the processing power of
our earlier enterprise
systems.

Figure 2 – The Lightning
9900 V Series is based
on an internal switched
architecture.

At the heart of the Lightning 9900 V Series is enormous capacity for throughput,
thanks to Hi-Star architecture. This network of interconnecting high-speed links to system
components provides an unequaled internal aggregate bandwidth of 15.9GB/sec
(gigabytes/sec) in the Lightning 9980V system. This bandwidth is divided into 10.6GB/sec
for data transfer and 5.3GB/sec for separate internal control information transfer. This
superhigh bandwidth is approximately 10 times that of competitive products.

The Lightning 9980V
system has an internal
bandwidth of

15.9GB/second.

Hitachi Data Sy s t e m s

The main components that make up the Lightning 9900 V Series systems are the
Array Control Processor modules (ACPs) and Host Adapter modules, called Channel Host
Interface Processors (CHIPs). These elements enable the unsurpassed bandwidth of the Hi­Star network by bringing their own network paths (and bandwidth) to the Cache
Hierarchical Star Network (C-HSN) and the Control Memory Hierarchical Star Network
(CM-HSN). This means that the full 15.9GB/sec internal bandwidth is available with a
fully configured Lightning 9980V system with all four ACP pairs (eight modules total) and
all four CHIP pairs (eight modules total). This is a truly high-performance and cost­effective configuration. With any Lightning 9900 V Series configuration, growing or scaling
can be easily completed by adding more CHIP pairs for connectivity or ACP pairs for more
capacity or performance. The internal bandwidth increases every time components are
added. The bandwidths stated are the rated bandwidths for the paths; the effective rates will
vary based on application workload and bandwidth consumption.

Although two ACP pairs are allowed for the Lightning 9970V system, more than one
pair is rarely needed except for scientific applications requiring massive bandwidth of raw
data from disk.

Bus contention is
virtually eliminated with
the Hi-Star architecture.

Figure 3 – A shared-bus
architecture is limited to
two simultaneous I/O
operations.

Limitation of Competitive Shared-bus Arc h i t e c t u res

Unlike the shared-bus architecture of some competitive products (as shown in Figure

3), Hi-Star internally switched architecture is designed to truly scale in both capacity and
performance and does not have to contend for limited bus bandwidth.

Hitachi is the only major
supplier of enterprise­class storage systems with
a 100 percent
availability guarantee.

The Lightning 9900 V Series Systems Have an Advanced Availability Pro f i l e
C o m p a red to Competitive Pro d u c t s

The Lightning 9900 V Series was designed with maximum emphasis on high­availability computing for today’s most critical enterprises. Chapter 7 discusses some of the
many advantages in high-availability design that the Lightning 9900 V Series has over
competitive products including:

• System microcode which can be upgraded nondisruptively

• Active/active dual-ported disk drives instead of single-port active drives

• Separate storage for control and configuration tables

• Mirrored cache instead of single image cache

2

• Offered by Hitachi Data Systems, the leading supplier of storage systems for
geographically GDPS™production sites

• NanoCopy™technology which offers a scheme for disaster recovery

• High-availability, custom-designed disk drives

Other Information Sources Available from Hitachi Data Systems

Additional information on the enterprise storage market, including an in-depth
overview of the technically advanced and unsurpassed software solutions available from
Hitachi Data Systems, is available in the companion publication, the Hitachi Freedom
Storage Software Solutions Guide. This document is downloadable in PDF format from

www.hds.com. The report contains expert guidelines regarding industry-leading software

solutions suites from Hitachi Data Systems for storage management, business continuity,
performance enhancement, backup and recovery, and data transfer. It also compares the
Hitachi Data Systems solutions to the major competitive software solutions and drills down
into specifics.

Since enterprise storage features are increasingly required in the modular storage
market, additional information on the Hitachi Freedom Storage Thunder 9500 V™Series
systems is available in a separate report entitled the Hitachi Freedom Storage Thunder
9500 V Series Architecture Guide. The Thunder 9500 V Series are modular (midrange)
RAID storage systems designed for use in heterogeneous open systems computing
environments and targeted at the e-commerce, Web serving, and data warehousing
applications. The Thunder 9500 V Series storage systems are the only modular products
that truly deliver large, enterprise-level features with a midrange package and price.

If further information is required, Hitachi Data Systems representatives can provide
specialized presentations, reports, and expert knowledge on the topics contained in this
series of reports.

Reduced TCO

Bandwidth contention in a shared-bus architecture serves as a limit to data hyper­consolidation initiatives and limits the enterprise’s ability to reduce TCO. Figure 4
illustrates that a recent survey showed that actual deployed average capacity of Lightning
9980V systems and Lightning 9970V systems exceeded that of fixed-bus systems by a factor
of 2.5x. Since the Lightning 9980V systems and Lightning 9970V systems nearly double
internal bandwidth of our earlier enterprise-level systems, it is clear that obstacles to massive
consolidation projects will be removed. This is especially true when the Hitachi industry­unique “virtual” Fibre Channel port feature of the Lightning 9900 V Series is considered.

The major objective of massive consolidation is to keep up with exploding storage
capacities without increasing head count and deploying staff to address the application
backlog. With the Lightning 9900 V Series, TCO can be reduced not only through
virtualization but also by:

• Reduced network complexity with fewer switches, connections

• Simplified and automated management tools and software

• Lower licensing, maintenance charges, and environmental costs

2

Some competitive products do n o t have dual cache like the Hitachi Freedom Storage Lightning
9900 V Series. If there is an unrecoverable error in cache, there is no duplicate backup copy. With
these products there is an increased risk of lost data, especially if the loss occurs in the hard w a re
status area. The Lightning 9900 V Series does not have this problem since all status areas and write
data are duplexed. Although a minor concern to some given the low probability of occurrence, the
thought of data loss is never comforting to enterprise executives charged with 24/7 operations.

Figure 5 – Today’s

Second-generation “Virtual” Switched Storage

An important key to lower TCO is the Lightning 9900 V Series “virtual” Fibre
Channel ports. Virtualization is becoming increasingly important in today’s heterogeneous
storage environment, which is made up of these storage architectures: direct attached
storage (DAS), storage area networks (SANs), and network attached storage (NAS), as
shown in Figure 5. This increases the need to centralize and efficiently manage all
heterogeneous storage with uniform enterprise policies and procedures.

6

As shown in Figure 6, the heterogeneous solutions of today require the separate
configuration of physical ports for each host platform type supported, particularly in high
availability path failover and clustered environments. This both increases expense through
unnecessary extra ports and limits heterogeneous consolidation, resulting in higher TCO.

9900 V Series virtual
Fibre Channel ports and

The Lightning 9900 V Series provides “virtual” Fibre Channel ports that are logically
managed by intelligent Fibre Channel controller cards. Each physical Fibre Channel port
may have multiple Host Storage Domains. A Host Storage Domain supports a “logical”
Fibre Channel port (Fig. 7) each with its own set of LUNs. Hosts are matched to their
assigned HSD based on a unique World Wide Names (WWNs) identifier. LUN security
provided by Hitachi SANtinel™software fences access to LUNs based upon host WWNs.
Under this innovative software structure, each of multiple host systems may have its own
unique LUN 0, from which it can boot, within its own Host Storage Domain.

The Hitachi Freedom Storage Lightning 9980V™System Packaging

The Lightning 9980V system is available in a two-to-five cabinet configuration (as
shown on the cover of this guide), depending on connectivity and capacity needs. A
Control Frame serves as the control center of each system and manages up to four Array
Frames that are connected via high-speed Fibre Channel links. A fully configured system is
contained in five cabinets 73.2 inches high, 148.9 inches wide, and 31.5 inches deep.

Lightning 9980V System Control Frame

The Control Frame of the Lightning 9980V system contains the Service Processor,
Client Host Interface Processor modules (CHIPs) with Fibre Channel adapters, ESCON
adapters, and/or FICON™adapters, Cache Modules, Cache Switch Modules (CSWs), Array
Control Processor modules (ACPs), power supplies, and battery modules. An illustration of
the Control Frame is shown in Figure 8.

Lightning 9980V System Array Frames

Each array frame of the Lightning 9980V system contains up to 256 Hard Disk Drive
(HDD) modules and communication interfaces to the Control Frame, for a total of 1024
drives for a maximum configured system. An Array Frame is shown in Figure 9.

This design allows for efficient centralized and consolidated storage, which results in
reduced management costs and lower overall TCO.

10

The Lightning 9900 V Series power systems consist of redundant power supplies in
both Control Frames and Array Frames. The power supplies are both hot pluggable and hot
swappable and are N+1 redundant. This means they can be removed or installed during
system operation and, if a power supply fails during operation, the failed power can be
dynamically removed without any loss to system operation. The Lightning 9900 V Series
power supply modules are shown in Figure 10.

Cables carry 48-volt main system power from the back of the Control Frame and Array

Frame where the power is converted to the required voltages.

Different AC power cord options allow all Lightning 9900 V Series models to connect

with the different electrical outlet configurations used around the world.

Hitachi Freedom Storage Lightning 9970V™System Packaging

Although the Lightning 9980V system has the ability to be upgraded from one to four
array frames, the Lightning 9970V™system is a fixed-configuration, single-cabinet storage
system. The Lightning 9970V system is targeted for IT environments where floorspace is at
a premium and data growth is limited, yet where premium storage functionality is required.
From the front, the Lightning 9970V system looks very much like the Control Frame of a
Lightning 9980V model. However, the back end contains HDD arrays housing up to 128
disks in a 73.2 inch high, 30.8 inch wide, and 31.5 inch deep footprint. This is shown in
Figure 11.

The System Monitoring Network of the Lightning 9900 V Series

Lightning 9900 V Series systems are designed with a system-monitoring network. The
system-monitoring cables are connected to all cabinets in Lightning 9900 V Series systems,
and they report a variety of system parameters, such as component failure, fan speed, power,
voltages, and temperature, to ensure trouble-free operation. This network not only provides
for efficient predictive maintenance (replacing a component before it fails), but also for the
failure alert system to expedite system repair after a component has failed. This information
is passed to the Control Frame, where it can be viewed either locally by the Service
Processor (SVP) or remotely by the Hitachi Resource Manager™storage package across a
private LAN on a UNIX®or Microsoft®Windows NT®console. Users can view failure
information via SNMP or IBM®S/390®SIMs. System status and alerts are also sent to
Hitachi Data Systems Customer Support Centers via the Hi-Track®“call-home” software
facility.

About the Fibre Channel Interface Board s

Each Fibre Channel Interface Board, as shown in Figure 13, has four Interface
Processors for management of connectivity to the host. Each port supports a transfer rate of
2Gbit/sec (gigabits/second) in conformance with the Fibre Channel standard. An optional
eight-port Fibre Channel Interface Board is also available.

14

With the Lightning 9900 V Series industry-leading implementation of “virtual” Fibre
Channel ports, each interface card is equivalent to multiple interface cards in competitive
systems. Each interface card also contains Oracle®checksum dedicated hardware logic.

Front-end Design of the Hitachi Freedom Storage Lightning 9900 V Se r i e s

There are four ports for each interface board or a total of 32 host interfaces for a fully
configured system. An ESCON interface board is shown in Figure 14. A FICON interface
board has a similar appearance. The FICON interface card is available with 1Gbit/sec or
2Gbit/sec transfer rates.

Hi-Star

™

Architecture – An
Internal Switched
Hierarchical Star Network

The Internal Hi-Star™A rc h i t e c t u re

The internal Hi-Star architecture consists of two separate networks: the Cache
Hierarchical Star Network (C-HSN) and the Control Memory Hierarchical Star Network
(CM-HSN).

The Cache Hierarchical Star Network

The C-HSN is the network used for transferring data to and from the main global data
cache. The C-HSN can also be broken down into two component networks: the processor
paths to the C-HSN and the actual C-HSN (as shown previously in Figure 2). Figure 16
p rovides a detailed illustration of the processor paths and the C-HSN of a Hitachi Fre e d o m
St o r a g e™Lightning 9900™V Series Lightning 9970V™system.

Figure 16 – The C-HSN
of a Lightning 9970V
system provides fully
redundant switched
access to cache from all
channel adapters.

17

Hitachi Data Sy s t e m s

The Cache Switch Provides Non-blocking Switched Access to Cache

The CSW is at the heart
of the Lightning 9900 V
Series.

A portion of cache
memory can be allocated
to specific data.

At the heart of the Lightning 9900 V Series are four Cache Switches (CSWs).
Together, these four switches (in the Lightning 9980V™system) use a parallel switch fabric
bus (PSFB). The CSW is a specially designed crossbar switch that functions as a
combination MUX, path arbitrator, and non-blocking network switch. The CSW functions
as a MUX by supporting eight paths into the processor side of each switch and eight paths
to the cache modules. All total, there are 32 paths at the processor side of the fabric
network and 32 paths to the cache modules from the cache side of the fabric network.

The Lightning 9980V System Provides 64GB of Fully Addressable Cache

The Lightning 9980V system supports up to 64GB of data cache, all directly
addressable. Separate cache modules (up to 3.0GB) are used for control storage.
Competitive systems use their cache for both data and control information, limiting the
amount of usable data cache and creating performance limitations for certain workloads.

Advanced Cache Algorithms of the Lightning 9900V Series

The Lightning 9900 V Series has a variety of advanced cache algorithms and software
solutions that provide exceptional performance.

Hitachi FlashAccess™S o f t w a re Allows Data Sets to be Permanently Placed
in Cache

Hitachi FlashAccess software allows users to dynamically “lock and unlock” data into
cache in real time. Read and write functions are then performed at cache speeds, with no
disk latency delay. FlashAccess software, a portion of cache memory can be allocated to
specific data. Administrators can add, delete, or change FlashAccess software managed data
at any time, quickly and easily.

In IBM®S/390®environments defined by the Logical Volume Image (LVI), cache data
can be as small as a single track or as large as a full 3390. For increased configuration
flexibility, FlashAccess software offers multiple modes of operation. It can be used in
conjunction with Hitachi RapidXchange™software to increase the speed of data transfer
and, therefore, improve performance of mainframes to open systems data exchange.
RapidXchange software supports both open-to-S/390 and open-to-open high-speed data
transfers.

18

Read-ahead for High-performance Sequential Reads

Read clustering in the Lightning 9900 V Series is enabled using built-in heuristics to
read ahead for every I/O. The heuristics are applied to determine if the data is being
accessed sequentially. If so, then the Lightning 9900 V Series reads ahead pages
corresponding to that data. Read-ahead helps to ensure that when a client read request is
received the requested data will already be stored in the data cache, so the request can be
satisfied immediately.

C o n t rol Memory Hierarchical Star Network

The second component of the Hi-Star architecture is the Control Memory Hierarchical
Star Network (CM-HSN). This is a point-to-point network that handles the exchange of
control information between the processors and control memory. The control memory
contains information about the status, location, and configuration of the cache, the data in
the cache, and the configuration of the Lightning 9900 V Series system (as well as other
information related to the operational state of the system). Two control memory areas are

Hi - St a r A rc h i t e c t u re – An In t e rnal Switched Hi e r a rchical Star Ne t w o rk

mirrored images of each other. This is illustrated in Figure 17. Control data is “data about
data,” also called “metadata.” Essentially, control information is handled
“out of band” from the data paths, both through a separate memory area and network.

The CM-HSN is a much simpler network design in that every connection is a
point-to-point connection. Only the Cache-HSN (data paths) uses a switched-fabric
topology for its interconnecting network. The CM-HSN also uses a narrower path and
more of them. Figure 17 shows a close-up view of the CM-HSN’s networking topology.
Referring back to the diagram in Figure 2, Chapter 1, there are two CM-HSN paths
connecting the processors to the control memory. However, the diagram in Figure 16 shows
four paths per processor module. There are up to 64 4-bit paths connecting the processors
to the control memory. The diagram in Figure 2 shows the 4-bit paths combined into their
full 8-bit (plus a parity bit) paths. The zoomed-in view in Figure 17 shows all of the ports
to the control memory in its “split” configuration. Again, control memory is mirrored. This
path topology is used to facilitate this mirrored architecture.

High-speed All Fibre Channel Back-end Design

Special high-performance back-end drives are available with the Hitachi Freedom

at 15,000RPM, and the 73GB and 146GB drives spin at 10,000RPM.

Each FC-AL path is driven with a dedicated processor. The diagram of a Lightning
9900 V Series ACP pair is shown in Figure 18. The Lightning 9900 V Series uses advanced
algorithms for managing performance of ACP pairs.

Maximum Configuration of ACPs and Disks

The maximum configuration of four ACPs and 16 Fibre Channel loops is shown in

New Fibre Channel Disk Drives

The back-end of the Lightning 9900 V Series uses dual ported/dual active Fibre
Channel disk drives. All the drives are 3.5" Low Profile (LP) 1"-height form factor with
capacities available in 36GB, 73GB, and 146GB drives. The 36GB drives spin at 15,000
RPM, and the 73GB and 146GB drives spin at 10,000RPM. These dual-ported/dual-active
Fibre Channel disk drives, combined with the technology built into the ACP pair, allow the
back end of Lightning 9900 V Series systems to use all eight FC-AL paths in an ACP pair
for both performance and fault tolerance. The ACPs monitor the activity and the utilization
of the paths. Based on this information, the ACPs determine the best path to use for
accessing a disk. A functional diagram of an Array Group with FC-AL disks is shown in
Figure 18.

The Importance of Command Tag Queuing (CTQ)

Another new feature introduced with the Lightning 9900 V Series is Command Tag
Queuing (CTQ) to the back-end drives. CTQ greatly improves the performance of
Lightning 9900 Series system back end by offloading much of the seek-optimization
functions to the disk drives themselves, to allow for more simultaneous back-end I/O
operations to occur.

Advantages of the Lightning 9900 V Series RAID Hard w a re

Hitachi designs the most advanced RAID (Redundant Array of Independent Disks)
controllers in enterprise storage to interface to its disk systems. These intelligent controllers
provide disk interface and RAID management, offloading these tasks to dedicated
processors. Each Lightning 9900 V Series ACP controller supports RAID-1+
and RAID-5 (parity RAID). All user data disks in the system are defined as part of a RAID
array of one type or another.

R A I D - 1 +

For the Lightning 9900 V Series, RAID-1+ is available in 2 Data + 2 Data and 4 Data +
4 Data disk arrangements in a RAID-1+0 configuration.

RAID-5 – Distributed Parity

RAID-5 disk arrangements for the Lightning 9900 V Series consist of four disks (3
Data and 1 Parity) of eight disks (7 Data and 1 Parity). Data is striped across RAID-5
arrays in a fashion similar to RAID-1+, but RAID-5 provides fault resilience by keeping
parity information on each stripe of data. If a failure occurs, the contents of that block can
be recreated by reading back the other blocks in the stripe along with the parity. Parity
information is distributed throughout the array to minimize potential bottlenecks in the
event of a need to rebuild data from a failed disk. The overhead of RAID-5 is equivalent to
one disk drive, regardless of the size of the array.

RAID Rebuild Capability

In the event of a disk failure, RAID-1+ or RAID-5 arrays can be rapidly and
automatically rebuilt using available “hot spare” drives. The Lightning 9900 V Series also
allows logical volumes to be expanded online. The 2D +2D RAID-1+ configuration and
3D + 1P and 7D + 1P RAID-5 configurations are shown in Figure 20.

RAID-1+ is unique to
Hitachi.

An Overview of High-availability (HA) Computing Software

It is increasingly important for a business to support continued access to global
information 24/7. What’s more, careers often depend on the availability of service levels
provided by IT to the enterprise.

In computer science, availability refers to the degree to which a system or resource is
capable of performing its normal function. Availability is measured in terms of Mean Time
Between Failure (MTBF) divided by MTBF plus the Mean Time to Repair (MTTR).

• AVAILABILITY = MTBF / (MTBF+MTTR)

For example, a server that fails on average once every 5,000 hours and takes an average
of two hours to diagnose, replace faulty components, and reboot, would have an availability
rating of 5,000/(5,000 + 2) = 99.96%. This would correspond to a Level 3 rating using the
Scale of 9s.

Availability refers to the

or resource is capable of

S o f t w a re Products Contribute to High-availability Computing

Many factors can cause unplanned downtime. The Hitachi Freedom Storage
Lightning 9900™V Series has been designed to eliminate as many of these factors as
possible in hardware redundancy, online replaceable components, and software data copy
functions. This allows copies of data at other locations either locally or remotely so that
processing can continue in the event of an outage.

Backup and restore procedures and products also contribute dramatically to computer
system availability by reducing the time to restore operations in the event of an outage.

Hitachi has teamed with industry-leading storage management software providers, such
as VERITAS®Software, to provide world-class high-availability solutions. These solutions
contribute to the fact that customers and analysts alike regard Hitachi Freedom Storage
systems as having the highest availability in the industry.

The Lightning 9900 V Series Has an Advanced Availability Profile Compared to
Competitive Pro d u c t s

The Lightning 9900 V Series was designed with maximum emphasis on high­availability computing for today’s most critical enterprises, including:

• System microcode that can be upgraded nondisruptively

• Active/active dual-ported disk drives instead of single-port drives or active/passive
dual-ported drives

• Redundant active components throughout the system, combined with automatic

The recovery process
without high-availability
middleware involves
time-consuming and
error-prone manual
operations.

26

Open Systems High-availability Middleware Support

Open-systems server vendors and third-party software vendors, such as VERITAS
Software, have developed a class of software known as “high-availability middleware” to
help reduce downtime by automatically detecting faults and recovering data services on a
redundant set of hardware. Without high-availability middleware, time is lost while a fault
goes undetected. Once the fault is detected, a diagnose/repair/replace action must take
place before data-service recovery can begin. High-availability middleware can begin an
automated recovery process immediately on the redundant hardware. The recovery process
without high-availability middleware involves time-consuming and error-prone manual
operations, which may include resetting the SCSI bus, restarting drivers, reassigning IP
addresses, recovering and restarting applications and transactions, and even rebooting.

4

Some competitive products do n o t have dual cache like the Lightning 9900 V Series
systems. If there is an unrecoverable error in cache, there is no duplicate backup copy. With
these products there is an increased risk of lost data, especially if the loss occurs in the
h a rd w a re status area. The Lightning 9900 V Series systems do not have this problem since all
status areas and write data are duplexed.

Hitachi Freedom Storage Lightning 9900 V Series Availability is Highest in the Industry

There are four basic types of high-availability middleware that can reduce downtime in
the event of a data path or host failure. The Lightning 9900 V Series supports each
classification of middleware:

A l t e rnate Pathing Middleware Switches the I/O Load in the Event of

Path Failure

This type of middleware automatically switches the I/O load on a failed primary
path to an alternate path on the same host system. The Lightning 9900 V Series
systems support alternate pathing for IBM AIX®, HP®True64™UNIX®,
HP-UX®and through PVlink, Microsoft®Windows NT®/Windows®2000, Sun
Solaris™,and IBM DYNIX/ptx®.

Hitachi Dynamic Link Manager™S o f t w a re Provides Path Failover and

Load Balancing

Hitachi Dynamic Link Manager™software is a family of Hitachi-provided
middleware software utilities that are ser ver-based, as shown in Figure 22.
Dynamic Link Manager software enhances the availability of RAID systems by
providing automatic-error recovery and path failover from server-to-RAID
connection failures. Dynamic Link Manager software provides load balancing in
addition to path failover by re-directing I/O activity to the least busy path using
complex algorithms.

Just because a system is RAID-protected doesn’t mean it is protected against
connection bus failures, which is why Dynamic Link Manager software is required
for true nonstop operations. This product allows systems administrators to take
advantage of the multiple paths on a Lightning 9900 V Series system by adding
redundant connections between application servers and RAID systems. Dynamic
Link Manager software therefore provides increased reliability and performance.
Supported platforms include IBM AIX, Sun Solaris, Windows NT,
Windows 2000, and LINUX®(July 2003).

Alternate pathing

the I/O load on a failed

Dynamic Link Manager
software provides load

Host Failover

Host failover software supports a cluster of host processors in which one of the
hosts automatically takes over the workload of any failed host in the cluster. This
“takeover” includes the reassignment of networks and peripherals, as well as the
restarting of applications. Host clustering can also be used to create fault-tolerant
workloads and scale processor capabilities while sharing network and disk
resources.

Lightning 9900 V Series systems supports all major open systems clustering
schemes including: HP TruCluster™, HP MC/ServiceGuard™, HP MC/Lock
Manager, IBM RS6000®and SP HACMP™, Windows NT/Windows 2000,
Microsoft Cluster Server, NCR UNIX SVR4 Lifekeeper, IBM DYNIX/ptx ATAP,

Clustering middleware
supports distributed lock
management.

Parallel Database Clustering

This type of middleware is a special version of host failover middleware, which
supports major parallel database servers like Oracle®Parallel Server, Informix
XPS, and Sybase®MPP. Clustering middleware supports distributed lock
management, a feature that enables parallel database software running on separate
cluster nodes to share access to the same database. If one host fails, the other hosts
can take over its work. Database clusters allow a customer to grow a database
incrementally simply by adding additional nodes. With non-parallel database
servers, the server has to be replaced or an additional server with another database
instance has to be purchased and installed when the capacity of the original
system is exceeded.

The Lightning 9900 V Series systems have been certified with MC/Lock Manager
for Oracle Parallel Server and Sun PDB for Oracle Parallel Ser ver.

S t a n d a rd Hot Swap and Redundant Power Supplies

The Lightning 9900 V Series provides fully redundant power supplies to ensure
uninterrupted power and cooling to all chassis in the system – supporting full system power
in the event of a power supply failure. In the event of such a failure, the power supply that
has failed can be “hot swapped” without disruption to the power system.

®

Hitachi Freedom Storage Lightning 9900 V Series Availability is Highest in the Industry

S t a n d a rd Redundant Fans for Cooling

The Lightning 9900 V Series provides fully redundant fans for uninterrupted cooling
to all components of the system. The speed and operation of these fans are monitored by
the environmental monitoring system. If a fan should fail, it can be “hot swapped” without
disruption to the cooling system.

Competitive Advantage in RAID Choices

The flexibility in choice for Lightning 9900 V Series RAID protection for disk drives is
unmatched. It is important to have choices in RAID protection since files and data have
different characteristics in terms of user required performance, uptime, and rebuild times.
RAID-1+ (mirroring) offers the highest performance (read from either disk in the mirror
pair) during normal operation. RAID-1+ also offers the highest performance in the event of
a failed disk since it is not necessary to read parity (and then data) in the event of a disk
failure in other RAID configurations.

The Lightning 9900 V Series also offers the capability to intermix RAID levels within
a system, depending on the level of availability and performance required by the data
hosted on the Lightning 9900 V Series system. For example, a single Lightning 9900 V
Series system can configure both RAID-1+ and RAID-5.

With the Lightning 9900 V Series flexible LUN configuration feature, the user can
select LUN sizes as small as 46MB or as large as almost 2TB (using LUSE).

Unmatched Performance
and Scalability

Truly Scalable Performance

Based on the internal switched Hi-Star™architecture, the Hitachi Freedom Storage
Lightning 9900™V Series shows unmatched performance scalability. This chapter discusses
the ability to dramatically add more online transaction processing (OLTP) users and mixed
decision-support and OLTP workloads without a user response time decrease. The more
capacity and connectivity added to a Lightning 9900 V Series system, the more total the
bandwidth increases. As Table 4 shows, total aggregate bandwidth is ten times that of
competition.

When new application workloads are added to a Lightning 9980V™system with an
existing workload, neither the new nor the existing workloads suffer performance
degradations from the sharing of internal resources and bandwidth. The following series of
tests proves this point. By measuring user-response time while workloads are added to the
system, we can illustrate this phenomenon.

I n t e rnal Switching Overcomes the Limitations of Shared-bus Arc h i t e c t u re s

It can be seen from Figure 24 that very little user-response time reduction occurs in the
OLTP performance of the Lightning 9980V system. This is because the Lightning 9900 V
Series system, with its Hi-Star architecture, essentially has its own internally routed path for
each workload. This means that the main reason for performance decline of a competitive
shared-bus architecture, i.e. bus contention, does not occur with Lightning 9900 V Series
systems. Although there may be some contention in cache, many simultaneous operations
concurrently happen at the cache, so it far exceeds the demands of most applications.

T h e re Is NO Match for the Performance of the Lightning 9980V System

As shown in Figure 23, during the first 30 minutes of the test 1800 simulated users
were connected to the first OLTP server, and the transactions per minute (TPM) rate and
user-response time reached steady state at about 2200TPM and 3.0 seconds respectively.
OLTP user response time is the delay time between when a simulated user issues a
transaction request and when the request responds with a commit. After 30 minutes, a
second OLTP server was connected with an additional 1800 simulated users, bringing the
total number of users to 3600.

After one hour, the first decision support system (DSS) workload was started. The DSS
workload began a series of full table scans, counting records from a 1.2 billion row table.
The transfer rate for the DSS system was 380MB/sec or 3.4 million rows per second. We

was managed by using Hitachi Priority Access software to limit the throughput for a
particular application. At this point, the two OLTP workloads were still able to sustain their
2200TPM each, or 4400TPM aggregate. The three combined workloads were allowed to
run for approximately 30 minutes together to obtain a steady state.

From 90 minutes to 150 minutes of the test, two more OLTP servers were added to
the workload of the Lightning 9980V system, bringing the total number of users to 7200
and the TPM to 8800, a linear increase from the time the first OLTP server was started
with a TPM of 2200.

From 150 minutes to 180 minutes of the test, the second and final DSS system started
its table scan activity. This mixed workload of six total servers (four OLTP and two DSS)
caused only a slight (2.6 percent) reduction in the first DSS system’s throughput from a
transfer rate of 380MB/sec to 370MB/sec. However, the two DSS systems were performing
full tables scans at an aggregate rate of about 740MB/sec or 6.6 million rows per second
each. During this time the total OLTP transaction rate was maintained at 8800TPM;
however, the average user-response time increased insignificantly to 0.38 seconds per
transaction. The 0.08 second increase was considered noise at these levels of measurement,
but is recorded here for discussion.

After three hours, the Lightning 9980V system was under a heavy mixed-performance
workload characterized by a mix of sequential reads at high bandwidths and random reads
and writes. Total processor utilization for the entire system was only 30 to 35 percent.

Series’ systems, Priority Access software and Host Storage Domains guarantee that the most
crucial applications get the highest level of service. FlashAccess allows users to quickly and
easily lock and unlock information into cache in real time. A user can confidently "fill it up
and max it out" to meet performance requirements using the maximum raw capacity of the
Lightning 9900 V Series system. Hitachi Parallel Access Volume (HPAV) software permits
multiple applications running on an S/390 server to access the same information
simultaneously. The Multiple Allegiance (MA) software solution extends the HPAV
software capability to applications running on multiple S/390 servers. Together, HPAV
software and MA software reduce queuing, which results in significantly decreased batch
times and swifter responses in today’s high-transaction environments.

Graph-Track software is a unique and effective tool that has the scope to monitor all
aspects of hardware performance from a centralized utility. Through a GUI, information
can be exported to multiple formats quickly and easily for analysis and reporting programs.
Graph-Track software displays real-time or historical information for all connected
Lightning 9900 V Series and Thunder 9500 V Series storage systems. Identifying utilization
peaks and ongoing trends positions users to make rapid and informed decisions as needed
to stay competitive. Dynamic Link Manager software automates I/O load balancing, path
failover, and recovery capabilities in the event a single path breaks down. In a unique
balancing act, Dynamic Link Manager software ensures that no single path becomes
congested and overworked while another is underutilized. By automatically allocating data
to an alternate path, the threat of application failure is removed. The Performance
Maximizer package includes Hitachi Performance Monitor and CruiseControl software for
intelligent performance tuning. The third component, Priority Access software, works with
port virtualization and VERITAS Volume Manager to provide the highest level of service
access available today.

Data Movement Suite

Information needs to be exchanged regularly for such tasks as data synchronization,
populating data warehousing systems, or application development and testing. Typically,
data is exchanged in either direction, between a mainframe and open systems. However, the
ever-diminishing mainframe batch window, coupled with increasing volumes of
information, often impedes this process. The Data Movement Suite includes three software
packages that eliminate many of the constraints related to exchanging information in
heterogeneous environments. RapidXchange software saves time as it delivers high
performance and reliable data sharing among heterogeneous host platforms. Swift
information transfer is achieved without placing additional burdens on the network
infrastructure or tape transport equipment. By improving exchange processes between
mainframe and open systems, the threat of over-stressing the network is reduced. When
combined with FlashAccess software, RapidXchange software delivers information even
faster to keep pace with widespread applications and their demands.

Multi-vendor file transfer capabilities are demonstrated in the Hitachi Data Systems
strategic alliance with Tantia Technologies. HARBOR File Transfer adds automation to
large data file transfers at ultrahigh channel speeds in either direction between open systems
and mainframe servers. After splintering large files into more manageable pieces, HARBOR
File Transfer and RapidXchange software direct the data in multiple streams through
Lightning 9900 V Series systems, making information available and accessible at mega rates.
With TrueCopy software, the Hitachi Data Systems team of experts ensures continuous
access to information while they carry out a client’s plan to restructure operations or
consolidate decentralized systems into an existing datacenter. Data Protection Services
incorporates components of the Business Continuity Suite for applications with industry­leading Hitachi Freedom Storage systems. This combination of services, software, and
storage provides a complete solution to help implement the processes involved in
duplicating and transferring data to both local and remote locations.

A Powerful and Open Systems Management Philosophy

The Hitachi Freedom Storage™Software Solutions support an enterprise’s strategic goal
of helping customers focus on their business issues, instead of on deploying enabling
technologies, by providing powerful centralized management capabilities. The many
advanced functions available on Hitachi Freedom Storage hardware are initiated, managed,
and controlled through the powerful HiCommand™Management Framework.

The Hitachi Freedom Storage Software Solutions also deliver enterprise-wide coverage
of online data copy/relocation, data access/protection, and storage system resource
management. Customers have the freedom to choose the precise solution – or combination
of solutions – appropriate for their environment.

HiCommand Management Framework Allows Systems Management of Hitachi
F reedom Storage and Software through the Enterprise’s Vendor of Choice

Hitachi Freedom Storage software and hardware solutions are managed through the
powerful HiCommand Management Framework, which was created to reduce operations
expense and increase business agility while enabling operational excellence. Through use of
standards-based application programming interfaces (APIs), Hitachi has ensured that any
independent software or hardware vendor (ISV or IHV) can develop products that
seamlessly integrate into the framework. The HiCommand Management Framework
encompasses storage resource management, configuration management and automation,
automated data replication and recovery, performance management and optimization, and
related functionality. Beginning with the HiCommand Device Manager and HiCommand
Tuning Manager modules, the framework will expand to provide a full suite of storage
management applications.

HiCommand Device Manager, the first module of the HiCommand Management
Framework, consists of three components: the Device Manager server, a Web-based
graphical user interface (GUI) browser, and Device Manager host agents that access
software management functionality. Most importantly, Device Manager software can plug
into other management frameworks. This feature provides the utmost in an open
architecture and leverages an enterprise's existing investments in software and skills.

HiCommand Tuning Manager software maps, monitors, analyzes, and reviews an
entire storage network’s resources, all from a consolidated single screen. Intuitive and Web­based, Tuning Manager software provides the necessary data to improve the administration­to-storage resource ratio, maintain IT service- and operating-level agreements, employ
predictive trending to forecast future storage requirements, generate storage reports for
current usage analysis, and set real-time capacity and performance metrics. The ability of
Device Manager software and Tuning Manager software to globally manage all Hitachi
Freedom Storage hardware and software is shown in Figure 25.

their storage environments than they have ever had in the past. However, most storage
managers are faced with administering a myriad of existing components and new, complex
storage topologies, which lack a clear and consolidated approach to management. It is no
longer good enough to provide basic services, such as LUN management, device monitoring
and backup; now, it is critical to provide integrated management of all aspects of storage
across a heterogeneous environment made up of multiple devices, such as SAN switches,
complex storage systems, and storage appliances. Customers have also invested heavily in
"point" solutions and systems management applications for their current environments.
However, it is not sufficient for a vendor to provide a replacement for existing technologies;
the vendor must provide a complete solution by allowing customers to leverage their
existing investments, whether they are in hardware, software, or people.

Hitachi Data Systems recognizes that no single vendor can meet all the storage
requirements for today’s enterprises. That’s why Hitachi Data Systems pr ovides an open
management platform, based on industry-standard management protocols, along with
high-value-add functional components, such as policy-based automation and heterogeneous
device management. This allows customers to incorporate multiple vendor offerings to
create a truly complete solution for managing and monitoring their storage environments.
HiCommand Management Framework supports a modular, building-block approach to
designing and addressing business-specific storage management requirements. As a result,
this framework enables customers to build the most suitable management environment

The HiCommand Management Fr a m e w o rk and Hitachi Re s o u rce Manager System Management So f t w a re

based on a combination of Hitachi products and best-of-breed storage hardware and
software. Likewise, Device Manager software is customizable to integrate easily with existing
infrastructures and accommodate future growth plans.

The Device Manager module simplifies management functions and enables integrated
administration of multi-vendor storage environments. Furthermore, standard storage
management operations come pre-loaded in the policy-based automation module. Device
Manager also provides definition tools and an easy-to-use GUI interface for automating
more complicated storage management processes, resulting in lowered TCO.

Open, Standards-based Approach

At the foundation of HiCommand Management Framework is a message bus (as
shown in Figure 26) that allows individual functional components to "plug and play."
Functional components are incorporated into the overall solution based on a usage of the
Common Information Model (CIM), and the Simple Object Access Protocol (SOAP)
provides a standard envelope for a messaging bus that enables simple plug-in of functional
modules. This model provides a clear set of information content for management and
monitoring of the entire storage and system environment. Using this object-model-based
approach, solutions can readily communicate with all network-attached devices and
perform a variety of configuration, administration, and other functions, allowing for a
complete, integrated hardware and software management environment. Adopting this
model is the key to overall interoperability in the storage and systems management
environments. If a solution component adheres to this model, then its management or
incorporation will be relatively straightforward.

Another industry standard, eXtensible Markup Language (XML), is fast becoming the
norm for data communication within an integrated environment. Using XML to express
the messages within the CIM model enables not only a common understanding of the
required content, but also a clear and universal understanding of the message format and
flexible application integration. Hitachi is creating an open and extensible architecture
using these two foundational standards.

Hitachi is creating an open and extensible architecture using these three foundational
standards. A more thorough discussion of the HiCommand Management Framework
initiative and the open industry standards can be found at

CIM Benefits to Customers

CIM answers customers’ demands for interoperability, creating more functional
management applications and enabling customers and integrators to construct multi-vendor
solutions more easily. Vendor adoption of CIM becomes a critical success factor for a
product’s inclusion in a heterogeneous storage management environment. Without CIM,
vendors would need to swap and maintain an increasing tangle of APIs. CIM provides a

41

standards.

common model with which all vendors can work. A CIM-enabled storage management
environment will deliver significant benefits to customers, including the ability to:

1. Overcome the Challenges Created by De-coupling Storage
Resources from Specific Server(s) in a SAN

Neither a single vendor solution nor individual point solutions can meet customers’
long-term comprehensive storage management and interoperability requirements.
Customers need assurance that products deployed today can be expanded and enhanced to
meet emerging interoperability requirements by adherence to open industry standards, such
as CIM.

2. View and Operate Networked Storage as a Holistic Resource

CIM provides a common, normalized, yet extensible view of these resources, their
relationships, and the operations that can be performed against them.

By spanning the management of all components in the storage stack, from the
application to the physical storage medium, CIM allows a management application to be as
focused or all-encompassing as it needs to be, all within a single standard.

3. Avoid Being "Locked" into a Proprietary Management Environment

Storage management vendors supporting heterogeneous, interoperable environments
must differentiate their value based on products, services, and solutions, and not because
their customers are locked into distinct management frameworks incompatible with other
SAN elements. Customers who choose new and innovative companies that can create
competitive or complementary functionality (built on existing management infrastructure
and components based on the CIM standard) realize investment protection, greater choice,
purchasing leverage, and additional options.

Overview of How the Systems Management Software Supports
Business Objectives

To be successful in today’s business environment, companies must attain the highest
levels of business agility, with maximum IT system efficiency and performance. The
“storage-centric” model of computing is widely accepted today. In this model “enterprise
data” is the most important element of the IT infrastructure. Explosively growing storage in
both centralized and distributed environments must be managed intelligently while
ensuring that storage data remains available to all who need it. Intelligent storage and
network management software suites like the Hitachi Resource Manager software package,
therefore, are at the heart of the enterprise’s ability to achieve high levels of performance
and availability to meet business objectives.

Shipped with every Hitachi Freedom Storage™Thunder 9500™V Series and Lightning
9900 V Series systems, these integrated software packages are used by storage managers to
display system configuration, create user name/password security for administrators, set up
RAID groups, allocate LUNs, expand LUNs, and format storage. Storage administrators
who need a flexible, easy-to-use configuration and error-management tool will find
Resource Manager software package is an ideal choice. Users can monitor and manage their
storage systems through a graphical user interface.

The Resource Manager software package can also help optimize performance by
providing valuable resource utilization information, such as I/O activity, cache usage, and
availability status/event notification. Administrators can use Password Protection to
authorize users. This provides protection against unauthorized access to the Management
mode of Resource Manager software, and stores the password list at the array. Reliable error
management and reporting offers a big breakthrough for IT troubleshooters who seek
rapid-fire detection and notification to maintain productivity.

The following is a description of the Resource Manager modules and capabilities
applicable to Thunder 9500 V Series and Lightning 9900 V Series systems as summarized
in Table 6.

1. Out-of-band Management

Two LANs can be attached to the Thunder 9500 V Series systems: an internal

systems, and the user’s intranet (public LAN), which allows users to access the
Resource Manager software package.

2. SNMP Support Ensures Compliance with All Major
Systems-management Platforms

The Resource Manager software package supports Simple Network
Management Protocol (SNMP). SNMP is the most widely used network­management protocol in the marketplace. System Information Messages (SIMs)
are converted to SNMP Management Information Blocks (MIBs) for use with the
Resource Manager software package, or the VERITAS®Storage Manager™, IBM
Tivoli®, CA™Unicenter®or HP®OpenView®. With CA Unicenter, “super MIBs”
allows the control of the Lightning 9900 V Series or Thunder 9500 V Series
systems using CA Unicenter commands. This out-of-band6reporting format
ensures that Resource Manager software can determine the status of your Hitachi
Freedom Storage system even if the data channel path is down.

The Hitachi Web Utility runs on Web browsers, such as Internet Explorer
and Netscape®Navigator®. These programs run under the Microsoft®Windows
and Sun™Solaris™operating systems and provide a user-friendly interface for the
Lightning 9900 V Series and Thunder 9500 V Series systems Remote Console –
Storage Navigator functions, which are all based on the use of Java agents.

®

4. Host Storage Domains

The Lightning 9900 V Series and Thunder 9500 V Series systems provide for
“virtual” Fibre Channel ports that are logically managed by intelligent Fibre
Channel controller cards. Each physical Fibre Channel port has multiple Host
Storage Domains or HSDs. An HSD supports a “logical” Fibre Channel port (see
Figure 27) each with its own set of logical units (LUNs). Hosts are matched to
their assigned HSD based on a unique World Wide Names (WWNs) identifier.
LUN security is provided by Hitachi SANtinel™software, which fences access to
LUNs based upon host WWNs. Under this innovative software structure, one
LUN is reserved for the command and control device.

5. Hitachi LUN Manager and LUN Expansion Manager Software Simplifies
Configuration Management and Reduces Staffing Costs

Hitachi LUN Manager software is an open systems management utility. With
LUN Manager software, open systems LUNs can be defined, configured, and
maintained. There is no more waiting for the hardware vendor to come and make
configuration changes. LUN Manager software includes an easy-to-use, GUI-based
interface that allows the definition of paths for LUNs, the reconfiguration of
LUN-to-port assignments, or the viewing of the Hitachi Freedom Storage remote
service information messages. Because LUN Manager software can assign multiple
paths to a single LUN, support of alternate path failover, path load balancing, and
clustered systems is possible. Running on a standard Windows-based PC
connected to the storage systems by a dedicated LAN, LUN Manager software can
support multiple systems.

Hitachi LUN Expansion Manager software features logical unit size expansion
that dramatically improves LUN flexibility. Multiple LUNs can be presented to

“Out-of-band” refers to the path that system management messages travel, which is a

d i ff e rent path from the data. “In-band” messages would compete with data for bandwidth.

connections.

the operating system as a single, large LUN. This capability simplifies storage
management because there are fewer LUNs to manage. Two levels of password
protection, user and administrator, ensure maximum data security. Users can view
only Hitachi Freedom Storage LUN configuration information, while
administrators can access all LUN configuration information and functions.
Administrators can customize access privileges for individual users, thus providing
maximum flexibility and control of these powerful management capabilities.

6. Hitachi SANtinel Software

SANtinel software controls host access to Hitachi Freedom Storage systems
LUNs in open systems, multiplatform, or SAN environments. This enables users
to restrict server access to only those LUNs for which they are authorized, as
shown in Figure 28.

SANtinel software for open systems, running on the Hitachi Freedom Storage
systems, allows administrators to define multiple HSDs for each physical Fibre
Channel port on the system. An HSD consists of a virtual (logical) Fibre Channel
port and an associated set of LUNs visible only via that logical Fibre Channel
port.

Connections from host servers arriving at the physical Fibre Channel port are
routed to the logical Fiber Channel port within the appropriate HSD based upon
the Fibre Channel WWN of the host.

The storage administrator creates the HSD, sets the host mode of the logical
Fibre Channel port within that HSD, and maps the LUNs to appear within that
HSD. Then the storage administrator authorizes a particular host to "see" an HSD
on that physical port by assigning the Fibre Channel WWN of that host to the
HSD in question.

Because the WWN is used to route connections to the appropriate HSD, the

WWN may only be assigned to a single HSD on each Fibre Channel port.

SANtinel software may be used to authorize multiple hosts to access a
particular HSD. SANtinel software may be further used to permit or deny a
particular host to access individual LUNs within the HSD, based upon the WWN
of the host.

SANtinel software may be used to create up to 128 HSDs per physical Fibre
Channel port. Each HSD may contain up to 256 LUNs, with the maximum
number of LUNs contained within all HSDs on a given Fibre Channel port
reaching 512.

7. Hitachi Virtual LUN and LUN Expansion Software

Virtual LUN software allows administrators to convert fixed-size volumes into
several smaller, variable custom-sized volumes. Using the Resource Manager
software, users can configure a specific number of megabytes to each custom
logical volume image LUN. Virtual LUN software improves data access
performance by reducing logical-device contention as well as host I/O-queue
times, which can occur when several frequently accessed files are located on a
single volume. Multiple LUN types can be configured within each RAID group.
Virtual LUN software enables administrators to more fully utilize the physical
storage capacity of the Hitachi Freedom Storage systems, while reducing the
amount of administrative effort required to balance I/O workloads.

When Virtual LUN software is used in conjunction with FlashAccess
software, the user can achieve even better data access performance than when
either Virtual LUN software or FlashAccess software is used alone.

The LUN Expansion Manager allows administrators to create virtual LUNs
that are larger by expanding the size of a selected LUN. The maximum size is
2TB.

8. Hitachi FlashAccess™S o f t w a re Allows Data to be “Locked and
Unlocked” in Cache On-the-fly

The Hitachi FlashAccess software utility allows users to dynamically “lock”

and “unlock” data into cache in real time. Read and write functions are then

performed at cache speeds, with no disk latency delay. With FlashAccess software,
a portion of cache memory can be allocated to specific data. Users can add, delete,
or change FlashAccess software managed data at any time, quickly and easily.

Defined by the LUN for open systems, cache data can be as small as a single
track or as large as an entire volume. For increased configuration flexibility,
FlashAccess software offers multiple modes of operation.

9. Remote Console – Storage Navigator

The Lightning 9900 V Series Remote Console – Storage Navigator is
provided as a Sun Java®-applet program, which can execute on any machine that
supports a Java Virtual Machine (JVM). The Remote Console – Storage Navigator
PC hosts the Remote Console – Storage Navigator Java-applet program and is
attached to the Lightning 9900 V Series system(s) via a TCP/IP local-area network
(LAN). When a Remote Console – Storage Navigator accesses and logs into the
desired service processor (SVP), the Remote Console applet is downloaded from
the SVP to the Remote and runs on the Web browser of the Remote Console PC.
In this way, the Remote Console communicates with the attached Lightning 9900
V Series systems via a TCP/IP network.

Two LANs can be attached to the Lightning 9900 V Series and Thunder
9500 V Series systems: an internal LAN (private LAN), which is used to connect
the SVPs of multiple systems, and the user’s intranet (public LAN), which allows
you to access the Remote Console – Storage Navigator functions from individual
Remote Console – Storage Navigator PCs. The Remote Console – Storage
Navigator communicates directly with the SVP of each attached system to obtain
system configuration and status information and send user-requested commands
to the system. The Lightning 9900 V Series systems’ Remote Console – Storage
Navigator Java-applet program is downloaded to the Remote Console – Storage
Navigator (Web client) from the SVP (Web server) each time the Remote Console
– Storage Navigator is connected to the SVP. The Remote Console – Storage
Navigator Java-applet program runs on Web browsers, such as Internet Explorer
and Netscape®Navigator®, which run under the Microsoft®Windows NT®,
Windows®2000, and Sun™Solaris™operating systems to provide a user-friendly
interface for the Lightning 9900 V Series Remote Console – Storage Navigator
functions.

utilization. This data pinpoints specific activities that may have a negative impact
on operations, and lets the user fine-tune the system so that it can be used to
maximum advantage.

Graph-Track software also highlights valuable cache information. Cache
read/write and read-hit ratios are reported in real time. Each system connected to
Graph-Track software can be tuned separately.

11. Hitachi Virtual Logical Volume Image Manager Software for S/390
E n v i ronments Allows Very Large to Very Small Vi r t u a l - v o l u m e
C o n f i g u r a t i o n

Hitachi Virtual Logical Volume Image (VLVI) Manager is a mainframe
software utility that optimizes Lightning 9900 V Series system capacity utilization
by allowing users to configure multiple virtual LVIs in place of an LVI. Data
volumes as small as a single cylinder or as large as a full 3390-9 can be defined.
Volume size is determined in cylinder increments. Each VLVI requires one
physical address, with a maximum of 4096 addresses per Lightning 9900 V Series
system. Different types of LVIs can coexist within an array-group with no need to
convert them to a common LVI. This feature maximizes array-group capacity and
enhances configuration flexibility. Hitachi VLVI Manager software improves
performance by reducing logical-device contention and operating-system queuing.
It also boosts remote copy performance by avoiding the need to copy the entire
volume.

48

Analysis Tool Kit

HiReturn™Investment Analysis Tool Kit

Most enterprises today require that financial investment analysis be prepared prior to
IT capital expenditures. Identifying hardware and software as "best-of-breed" is no longer
sufficient justification for a major investment. Networked storage infrastructures and
consolidated storage systems have generally appeared to be cost-effective IT strategies, but
in order to commit to significant capital expenditures, today’s decision-makers seek detailed,
real-world information on operating expenses. With this in mind, Hitachi Data Systems
provides the HiReturn™investment analysis tool kit so that customers can make informed
capital expenditure IT decisions.

HiReturn is a collection of return on investment (ROI) tools, methodologies, best
practices, industry empirical data, and one-on-one coaching that allows customers to

Availability

In computer science, availability refers to the degree to which a system or resource is
capable of performing its normal function. Availability is measured in terms of Mean
Time Between Failure (MTBF) divided by MTBF plus the Mean Time to Repair
(MTTR). The availability equation is expressed as follows:

AVAILABILITY = MTBF / (MTBF+MTTR).
For example, a server that fails on average once every 5,000 hours and takes an average

of two hours to diagnose, replace faulty components, and reboot, would have an
a va i l a b i l i t y rating of 5,000/(5,000 + 2) = 99.96%. This would correspond to a Level 3
rating using the Scale of 9s.

Byte

A unit of data that is eight binary digits long and represents one text character.

Back End

In reference to storage arrays, the back end includes the controllers, disk drives, and
paths to the disk drives. On the Hitachi Freedom Storage™Lightning 9900™V Series
these are the ACP pairs, the Fibre Channel loops, and the Fibre Channel disks.

56

Bit

Eight bits compose a byte. This term is spelled out in compound abbreviations
(Mbit/sec and Gbit/sec) to avoid confusion with abbreviation for byte - B (as in MB or

types of caching are commonly used in personal computers: memory caching and disk
caching. Disk caching can dramatically improve the performance of applications,
because accessing a byte of data in RAM can be thousands of times faster than
accessing a byte on a hard disk. When data is found in the cache, it is called a cache
hit, and the effectiveness of a cache is judged by its hit rate.

100Mbit/sec standard that is compatible with existing 10BaseT installations, preserving
the CSMA/CD media access control (MAC) protocol.

Fast Write

A write operation at cache speed that does not require immediate transfer of data to a
disk drive. The system writes the data directly to cache, to nonvolatile storage, or to
both. The data is then available for de-staging (writing to disk). Fast write reduces the
time an application must wait for the I/O operation to complete.

FC

Fibre Channel.

FCA

Fibre Channel

Fibre Channel is an ANSI standard designed to provide high-speed data transfers

among workstations, servers, desktop computers, and peripherals. Fibre Channel makes

use of a circuit/packet switched topology capable of providing multiple simultaneous

point-to-point connections between devices. Fibre Channel is widely deployed in SAN

implementations today. Standards for Fibre Channel SANs are being worked on by the

Storage Networking Industry Association (SNIA). The technology has attracted interest

as a channel for the attachment of storage devices, but it has a limited popularity as a

high-speed networks interconnect. Fibre Channel can be deployed in point-to-point,

arbitrated loop (FC-AL), or switched topologies. Fibre Channel nodes log in with each

other and the switch to exchange operating information on attributes and

characteristics. This information includes port names and port IDs and is used to

establish interoperability parameters.

FICON

™

FICON is an IBM®trademark for Fibre Connection technology (ESCON®over Fibre

Channel).

File Backup

The practice of copying a file that is stored on disk or tape to another disk or tape is

referred to as file backup. This is done for protection in case the active file gets

damaged. Backup is considered “local copy” as opposed to “remote copy.” See also

Remote Copy.

Front End

In reference to storage arrays, the front end is considered to be the interfaces or ports

to the “real world,” the processors servicing these ports, and in some cases the cache

memory. On the Htachi Freedom Storage™Lightning 9900™V Series systems, the

front end consists of CHIP pairs.

GB

Abbreviation for gigabyte.

™

Java

Developed by Sun Microsystems™, Java is now a standard software language for
developing plug-in applications.

LAN

Local area networks or LANs are networks of computers that are geographically close
together; this usually means on the same campus. Most LANs are confined to a single
building or group of buildings. However, one LAN can be connected to other LANs
over any distance via telephone lines, high-speed fiber optic backbones, and radio
waves. A system of LANs connected in this way is called a wide-area network (WAN).

Lightning 9900™V Series

The Hitachi Freedom Storage™Lightning 9900™V Series was announced in May 2002
(Lightning 9980V™and Lightning 9970V™models). It represents a major advance in
enterprise-class storage systems with its Hierarchical Star Network switched internal
architecture, which provides for many times more simultaneous transfers to and from
the host compared to shared-bus architectures.

Logical Unit

The SCSI term for a logical disk drive.

66

Logical Unit Number

See LUN.

Logical Volume

The storage medium associated with a logical disk drive. A logical volume typically

resides on one or more storage devices. A host system sees a logical volume as a

physical volume, although it does not correlate directly with a physical disk drive.

LUN

Logical Unit or Logical Unit Numbers. A SCSI term for the field in an identifying

message that is used to select a logical unit on a given target.

LPAR

LPAR or logical partition is an IBM®ESA/390®term for a set of functions that create

the programming environment that is defined by the ESA/390 architecture. ESA/390

architecture uses this term when more than one LPAR is established on an ESA/390

server. An LPAR is conceptually similar to a virtual machine environment, except that

the LPAR is tied to one or more physical processors in a tightly coupled multiprocessor

system. Also the LPAR does not depend on an operating system to create the virtual

machine environment.

Operating system

The operating system is the most important software program that runs on a
computer. The operating system (OS) performs basic tasks such as recognizing input
from a keyboard, sending output to the display screen, keeping track of files and
directories on the disk, and controlling peripheral devices, such as disk drive and
printers or a mouse. The OS acts as a traffic cop and schedules the various programs
that the computer executes. The OS is also responsible for security, ensuring that
unauthorized users do not access the system. Operating systems can be classified as
follows:

1) Multi-user – allows two or more users to run programs at the same time

2) Multi-processing – supports running a program on more than one CPU

3) Multi-tasking – allows more than one program to run concurrently

4) Multi-threading – allows different parts of a single program to run
concurrently

5) Real Time – usually a stripped down OS that responds to input instantly

Out of Band

A communication that does not use the same bandwidth that carries data in a system.
For example, the control information in the Hitachi Freedom Storage

™

Lightning 9900™V Series systems do not use the same path as data and is therefore
referred to as “out of band.”

Parity

A data-checking scheme used in a computer system to ensure the integrity of the data.
The RAID implementation uses parity to recreate data if a disk drive fails.

PiT

A Point-in-Time (PiT) copy is a copy of data that is taken at a specific point in time.
PiT copies are used in many ways, including backups and checkpoints.

POD

Performance on Demand.

Port/Port ID

See Fibre Channel.

QoS

70

Quality of Service refers to service level agreement (SLAs) between users and the IT
organization. See also SLA.

RAID

Redundant Array of Independent Disks. RAID is used to increase the reliability of disk
arrays by providing redundancy either through complete duplication of the data
(RAID-1, i.e., mirroring) or through construction of parity data for each data stripe in
the array (RAID-3, -4, -5). RAID-5, which distributes parity information across all
disks in an array, is among the most popular means of providing parity RAID since it
avoids the bottlenecks of a single parity disk. The Hitachi Freedom Storage™Lightning
9900™V Series algorithms enable performance from RAID-5 that is competitive with
some vendors’ RAID-1.

RAID Controllers

RAID controllers provide a highly optimized scheme for securely managing RAID
configurations on storage systems. Hitachi RAID controllers allow RAID arrays to be
expanded online and support conversion of an array from one RAID level to another.

Recovery Time

The period from the disaster declaration to the recovery of the critical functions.

Gl o s s a ry

Remote Copy

Remote Copy refers generically to software or hardware utilities that provide the
capability to copy data from one online volume to remote volumes without disruption.
Synchronous techniques are used for short distances (typically less than 25 miles), and
asynchronous techniques over LAN/WAN/MAN are used at any distance.

Remote Copy Links

This term refers to the links used between storage systems for the movement of data.
Today these links are either direct-connect ESCON®, Fibre Channel, or network links
(T3, ATM, etc). For direct-connect ESCON there is a limit of 43km (25 miles). For
direct-connect Fibre Channel the limit is 10km. However, newer technologies, such as
the Nortel™OPTERA™product, are allowing direct fibre connect over longer
distances.

Risk Management

The discipline that ensures that an organization does not assume an unacceptable level
of risk.

SAN

Storage area networks (SANs) connect storage systems to servers through Fibre
Channel or Ethernet switches. Hitachi's implementation of SAN is known as Hitachi
SAN™and falls under the larger Hitachi Freedom Data Networks™umbrella. Major
benefits of SANs include outboard backup, sharing of resources, pooling, and reduced
cost of storage management. SANs are high-speed subnetworks of shared storage
devices. SAN architecture works in a way that makes all storage devices available to all
servers on a LAN or WAN. Because stored data does not reside directly on any of a
network's servers, server power is utilized for business applications, and network
capacity is released to the end user. See also Fibre Channel.

71

Hitachi Data Sy s t e m s

SCSI

Small Computer System Interface. An intelligent bus-level interface that defines a
standard I/O bus and a set of high-level I/O commands. There are currently many
flavors of SCSI defined by different bus widths and clock speeds. The seven major
variations of SCSI are SCSI 1, SCSI 2 (Fast/Narrow), SCSI 2 (Fast/Wide), Ultra SCSI
(Fast/Narrow), Ultra SCSI (Fast/Wide) – also called SCSI 3, Ultra 2 SCSI (Narrow),
Ultra 2 SCSI (Wide). See also Fibre Channel.

Serverless Backup

Using the eXtended SCSI command, and products like VERITAS®NetBackup™, the
Hitachi Freedom Storage™Lightning 9900™V Series offers serverless and LANfree
backup.

SLA

Service level agreements or SLAs are agreements regarding level of service between user
departments and the IT department. SLAs refer to all aspects of IT service, including
availability, performance, and repair.

Snapshot

A term that refers to a copy of a file system at a certain point in time. Snapshots are
used for backup and recovery.

SNMP

Simple Network Management Protocol. SNMP is a protocol used for communication
between simple, server-resident SNMP agents that respond to network administration
requests from simple-to-sophisticated SNMP manager tools running on remote
workstations.

Solaris

The Sun™UNIX®operating system based on System V, release 4.

Stripe

In RAID terminology, a stripe is when data is read or written in parallel to or from
multiple disks instead of reading or writing all data to one disk. Striping provides
much higher performance through its parallel design.

SVP

Service Processor of the Lightning 9900 V Series.

72

SWAN

Storage Wide Area Networks (SWANs) are interconnected SANs over long distances.
They are made possible by Fibre Channel and ESCON®extenders.

Swi tch

A switch is a network device that examines and forwards packets between LAN
segments.

Synchronous

Synchronous communications occur when the transmission of data between two
devices is synchronized with a clocking scheme or other technique. The sender and
receiver need to synchronize with one another before data is sent. In synchronous
communication, the bit stream and the clock pulse are synchronized by a special bit
transition pattern in the digital signal, creating an exactly timed stream of bits from the
sending device to the receiving device. An example of such a mechanism is bipolar
encoding. Synchronous communication is either character or bit oriented. Character
oriented synchronous transmissions are used to send blocks of characters, such as those
found in ASCII (American Standard Code for Information Interchange) files.
Bit-oriented synchronous communication is used primarily for the transmission of
binary data. See also Asynchronous Remote Copy and Hitachi TrueCopy™.

TCO

Gl o s s a ry

Total cost of ownership or TCO is a computer industry financial method of identifying
the cost of operating computer equipment. TCO includes depreciated capital costs,
manpower expense, power costs, communication costs, overhead, etc.

TCP

Transmission Control Protocol or TCP is a transport layer component of the Internet’s
TCP/IP protocol suite. It sits above IP in the protocol stack and provides reliable data
delivery services over connection-oriented links. TCP uses IP to deliver information
across a network and makes up for the deficiency of IP, providing a guarantee of
reliable delivery services that IP does not. TCP messages and data are encapsulated into
IP datagrams and IP delivers them across the network.

Volume

An IBM®ESA/390®term for the information recorded on a single disk unit or
recording medium. Indirectly, a volume can refer to the unit of recording medium
itself. On a non-removable medium storage device such as a disk drive, the terms may
also refer, indirectly, to the storage device that is associated with the volume. When a
user stores multiple volumes on a single storage medium transparent to the program,
the volumes are referred to as logical volumes.

WAN
