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.

Other reports, presentations, and expert knowledge are also available.
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 heterogeneous IT environment demands virtualization of storage.
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.

Figure 7 – The Lightning 9900 V Series virtual Fibre Channel ports and Host Storage Domains.
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.

Figure 9 – A Lightning 9980V system Array Frame with its major components.
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.

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.
