    The Lightning 9900™ provides up to 32 host interface ports and can be configured for all-mainframe, all-open, or multiplatform operations.

  • Page 16: Continuous Data Availability

    (compatible with ESCON all-open, and multiplatform configurations. When FICON™ channel interfaces are used, the 9900 subsystem can provide up to 16 logical control unit (CU) images and 4096 logical device (LDEV) addresses. Each physical FICON™ channel interface supports up to 512 logical paths providing a maximum of 8192 logical paths per subsystem.

    1 GB to 32 GB. All disk drive and cache upgrades can be performed without interrupting user access to data. The 9900 subsystem can be configured with the desired number and type of front-end client- host interface processors (CHIPs). The CHIPs are installed in pairs, and each CHIP pair offers up to eight host connections.

  • Page 23: Reliability, Availability, And Serviceability

    Reliability, Availability, and Serviceability The Lightning 9900™ subsystem is not expected to fail in any way that would interrupt user access to data. The 9900 can sustain multiple component failures and still continue to provide full access to all stored user data. Note: While access to user data is never compromised, the failure of a key component can degrade performance.

    For the 9910 subsystem, the controller frame also contains the disk array components. The 9900 controller is fully redundant and has no active single point of failure. All controller frame components can be repaired or replaced without interrupting access to user data.

    (called cache A and cache B) on separate cards. Cache A is in cluster 1, and cache B is in cluster 2. The 9900 places all read and write data in cache. Write data is normally written to both cache A and B with one CHIP write operation, so that the data is always duplicated (duplexed) across logic and power boundaries.

  • Page 30: Multiple Data And Control Paths

    The 9900 does not have any common buses, thus eliminating the performance degradation and contention that can occur in a bus architecture. All data stored on the 9900 subsystem is moved into and out of cache via the redundant high-speed paths.

    The cache management algorithms (see section 3.3.1) enable the 9900 to stage up to one full RAID stripe of data into cache ahead of the current access to allow subsequent access to be satisfied from cache at host channel transfer speeds.

    2.4.3 Device Emulation Intermix The 9900 subsystem supports an intermix of different device emulations (e.g., 3390-x LVIs, 3380-x LVIs, OPEN-x LUs) on the same ACP pair. Figure 2.8 illustrates an intermix of device emulation types. The only requirement is that the devices within each array group must have the same type of track geometry or format, as follows: 3390-1, -2, -3 or -9 can be intermixed within an array group.

    I/O (e.g., sequential). Fast write: All write I/Os to the 9900 subsystem are fast writes, because all write data is written to cache before being destaged to disk. The data is stored in two cache locations on separate power boundaries in the nonvolatile duplex cache (see section 2.2.3).

  • Page 44: Cache Management

    3.3.1 Algorithms for Cache Control The 9900 subsystem places all read and write data in cache, and 100% of cache memory is available for read operations. The amount of fast-write data in cache is dynamically managed by the cache control algorithms to provide the optimum amount of read and write cache, depending on the workload read and write I/O characteristics.

    The 9900 subsystem supports the following logical CU images (emulation types): 3990-3, 3990-6E, and 2105. The 9900 subsystem is configured with one logical CU image for each 256 devices (one storage subsystem ID (SSID) for each 64 or 256 devices) to provide a maximum of sixteen CU images per subsystem.

    The 9900 subsystem’s global cache provides a “share-everything” architecture that enables any fibre-channel port to have access to any LU in the subsystem. In the 9900, each LU can be assigned to multiple fibre-channel ports to provide I/O path failover and/or load balancing (with the appropriate middleware support) without sacrificing cache coherency.

    4.2.3 Defining the 9900 to VM/ESA 64 or Fewer LVIs: To define a 9900 with less than or equal to 64 LVIs to a VM/ESA use the same procedure as for an IBM 9900 with more than 64 LVIs to VM/ESA sharing option for the subsystem as shown below (the address range varies for each installation).

  • Page 85: S/390 ® Operations

    Since the 9900 is a RAID device, there are only a few differences in operation from conventional DASD or other RAID devices. Table 4.6 lists ICKDSF commands that are specific to the 9900, as contrasted to RAMAC.

  • Page 87: Mvs Cache Operations

    To display the 9900 cache statistics under MVS DFSMS, use the following operator command: D SMS, CACHE. Figure 4.22 shows the cache statistics reported by the 9900. The 9900 reports cache statistics for each SSID in the subsystem. Because the dynamic cache management algorithm has been enhanced, the read and write percentages for the 9900 are displayed as N/A.
  • Page 88 Due to this advance track transfer, the 9900 shows the number of tracks transferred from the disks to the cache slot at DASD/CACHE of the SEQUENTIAL in TRANSFER OPERATIONS field in the subsystem counters report, even though the access mode is not sequential.

    EREP SIM report on a regular basis. Since all SIMs are also logged the 9900 Remote Console PC, the user can also use the Remote Console PC to monitor the SIMs.

  • Page 90: Open-Systems Configuration

    9900 disk devices for open-system operations, please refer to the 9900 configuration guide for the connected platform. Table 4.7 lists the currently supported platforms and the 9900 configuration guides. Please contact your Hitachi Data Systems account team for the latest information on platform and software version support.

  • Page 91: Configuring The Fibre-Channel Ports

    The 9960 subsystem supports a maximum of 32 fibre-channel ports, and the 9910 supports up to 24 fibre-channel ports. Each fibre-channel port is assigned a unique target ID (from 0 to EF). The 9900 subsystem supports up to 256 LUNs per port. Figure 4.24 illustrates fibre port- to-LUN addressing.

  • Page 92: Open Systems Operations

    9900 subsystem processes requests in the most efficient order to minimize head seek operations and disk rotational delay. Note: The queue depth parameter may need to be adjusted for the 9900 devices. Please refer to the appropriate 9900 configuration guide for queue depth requirements and instructions on changing queue depth and other related system and device parameters (refer to Table 4.7 for a list of the 9900 open-system configuration guides).

  • Page 93: Path Failover Support

    The user should plan for path failover (alternate pathing) to ensure the highest data availability. In the open-system environment, alternate pathing can be achieved by host failover and/or I/O path failover software. The 9900 provides up to 32 fibre ports to accommodate alternate pathing for host attachment. Figure 4.25 shows an example of alternate pathing.

    5.7.4 Air Flow Requirements The 9900 subsystem is air cooled. Air must enter the subsystem through the air flow intakes at the sides and bottoms of the frames and must be exhausted out of the tops and sides, so it is very important that the air intakes and outlets remain clear. Hitachi Data Systems recommends that under-floor air cooling has a positive pressure and meets the specifications listed in Table 5.20.

    5.7.5 Vibration and Shock Tolerances Table 5.21 lists the vibration and shock tolerance data for the 9900 subsystem. The 9900 can be subjected to vibration and shock up to these limits and still perform normally. The user should consider these requirements if installing the 9900 near large generators located on the floor above or below the 9900 subsystem.

    9900 ensure full recovery from disk drive failures and non-stop access to all user data. Due to the 9900’s architecture, data can remain pinned in cache if it is not accessed by the host following the pinned track condition. Certain 9900 maintenance activities (e.g., microcode updates) require that all pinned tracks be cleared.
