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.

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

•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 FreedomStorage 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 Thunder9500 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.

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.

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.

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.

Packaging
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.
Hitachi Freedom Storage Lightning 9900 V Series Pa c k a g i n g
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.
Figure 10 – Power
supply modules for the
Lightning 9900 V Series

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.

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.
