1 Introduction P9500 overview The P9500 is a high capacity, high performance disk array that offers a wide range of storage and data services, software, logical partitioning, and simplified and unified data replication across heterogeneous disk arrays. Its large scale, enterprise class virtualization layer combined with Smart Tiers and Thin Provisioning software, delivers virtualization of internal and external storage into one pool.
The following sections provide descriptions and illustrations of the P9500 disk array and its components. Figure 1 P9500 disk array NOTE: Each Rack is 600mm wide without side covers. Add 5mm to each end of entire assembly for each side cover. Controller chassis The controller chassis (factory designation DKC) includes the logical components, memory, disk drive interfaces, and host interfaces.
the rack because it is the heavier of the two units. If a system has two SVPs, both SVPs are mounted in controller chassis #0. The following illustration shows the locations of the components in the controller chassis. The controller chassis is described in more detail in “System components” (page 54).
Figure 3 Disk Unit Features This section describes the main features of the P9500 disk array. Scalability The P9500 disk array is highly scalable and can be configured in several ways as needed to meet customer requirements: • The minimum configuration is a single rack containing one controller chassis and two drive chassis. • One to three racks containing one controller chassis and up to eight drive chassis. A drive chassis can contain up to 128 2 1/2 disk drives or 128 SSDs. Drives can be intermixed.
Figure 4 Example P9500 disk array configurations In addition to the number of disk drives, the system can be configured with disk drives of different capacities and speeds, varying numbers of CHAs and DKAs, and varying cache capacities, as follows: • Two to six CHAs (each is a pair of boards). This provides a total of 12 when all of the CHA slots are used and there are no DKAs installed, as in a diskless system. The maximum total number of CHAs and DKAs is 12.
Connectivity P9500 The P9500 Disk Array supports most major IBM Mainframe operating systems and Open System operating systems, such as Microsoft Windows, Oracle Solaris, IBM AIX, Linux, HP-UX, and VMware. For more complete information on the supported operating systems, contact HP Technical Support. P9500 supports the following host interfaces. They can mix within the disk array.
generates less heat, the fan speed is reduced, saving energy and reducing the noise level of the system. When the disk array is in standby mode, the disk drives spin down and the controller and drive chassis use significantly less power. For example, a system that consumes 100 amps during normal operation, uses only 70 amps while in standby mode. Specifications The following tables provide general specifications of the P9500. Additional specifications are located in “Specifications” (page 80).

Table 4 Performance management features and functions Feature Description Cache Residency Cache Residency locks and unlocks data into the cache to optimize access to the most frequently used data. It makes data from specific logical units resident in a cache, making all data accesses become cache hits. When the function is applied to a logic unit, frequently accessed, throughput increases because all reads become cache hits.
Table 7 Data replication features and functions (continued) Feature Description Continuous Access Synchronous Z systems. Continuous Access Synchronous Z provides synchronous copy for mainframe systems. Business Copy and Creates internal copies of volumes for purposes such as application testing and offline backup. Can be used in conjunction with True Copy or Continuous Access Journal to maintain multiple copies of data at primary and secondary sites.
Table 10 Host server based features and functions Feature Description RAID Manager On open systems, performs various functions, including data replication and data protection operations by issuing commands from the host to the HP disk arrays. The RAID Manager software supports scripting and provides failover and mutual hot standby functionality in cooperation with host failover products.
2 Functional and operational characteristics System architecture overview This section briefly describes the architecture of the P9500 disk array. Hardware architecture The basic system architecture is shown in the following diagram. Figure 5 P9500 architecture overview The system consists of two main hardware assemblies: • A controller chassis that contains the logic and processing components • A drive chassis that contains the disk drives or solid state drives.
The P9500 supports the following RAID levels: RAID1, RAID5, RAID6. RAID0 is not supported on the P9500. When configured in four drive RAID5 parity groups (3D+1P), ¾ of the raw capacity is available to store user data, and ¼ of the raw capacity is used for parity data. RAID1. Figure 6 (page 18) illustrates a sample RAID1 (2D+2D) layout. A RAID1 (2D+2D) array group consists of two pairs of data drives in a mirrored configuration, regardless of data drive capacity.
Figure 7 Sample RAID5 3D + 1P layout (data plus parity stripe) RAID6. A RAID6 array group consists of eight data drives (6D+2P). The data is written across the eight drives in a stripe that has six data chunks and two parity chunks. Each chunk contains either eight logical tracks (mainframe) or 768 logical blocks (open). In the case of RAID6, data can be assured when up to two drives in an array group fail. Therefore, RAID6 is the most reliable of the RAID levels.
Figure 8 LDEV striping across 2 RAID5 (7D+1P) array groups Figure 9 LDEV striping across 4 RAID5 (7D+1P) array groups All data drives and device emulation types are supported for LDEV striping. LDEV striping can be used in combination with all P9500 data management functions. CU Images, LVIs, and Logical Units This section provides information about control unit images, logical volume images, and logical units.
The mainframe data management features of the P9500 may have restrictions on CU image compatibility. For further information on CU image support, see the Mainframe Host Attachment and Operations Guide, or contact HP. Logical Volume images The P9500 supports the following mainframe LVI types: • 3390-3, -3R, -9, L, and -M. The 3390-3 and 3390-3R LVIs cannot be intermixed in the same disk array. • 3380-3, -F, -K.
Mainframe operating system support The P9500 disk array supports most major IBM Mainframe operating systems and Open System operating systems, such as Microsoft Windows, Oracle Solaris, IBM AIX, Linux, HP-UX, and VMware. For more complete information on the supported operating systems, go to: http:// www.hp.com Mainframe configuration After a P9500 disk array has been installed, users can configure the disk array for mainframe operations.

4 Power On/Off procedures Safety and environmental information CAUTION: Before operating or working on the P9500 disk array, read the safety section in the HP XP P9000 Site Preparation Guide and the environmental information in “Regulatory compliance notices” (page 85). Standby mode When the disk array power cables are plugged into the PDUs and the PDU breakers are ON, the disk array is in standby mode. When the disk array is in standby mode: • The Basic Supply (BS) LED on the control panel is ON.
Follow this procedure exactly when powering the disk array on. Refer to the illustration of the control panel as needed. 1. On the control panel, check the amber BS LED and make sure it is lit. It indicates that the disk array is in standby mode. 2. In the PS area on the control panel, move the Enable switch to the ENABLED position. Hold the switch in the Enabled position and move the PS ON switch to the ON position. Then release the ENABLE switch. 3.
When a power failure occurs and continues for 20 milliseconds or less, the disk array continues normal operation. If the power failure exceeds 20 milliseconds, the disk array uses power from the batteries to back up the cache memory data and disk array configuration data to the cache flash memory on each cache board. This continues for up to ten minutes. The flash memory does not require power to retain the data. The following illustration shows the timing in the event of a power failure.
Support to move the batteries to a disk array that is being used, or turn the disk array on to standby mode for at least 3 hours once every two weeks. If you store the system for more than two weeks and do not disconnect the cache destage batteries, when you restart the system, the batteries will need to charge for at least 90 minutes before the cache will be protected.
5 Troubleshooting Solving problems The P9500 disk array is highly reliable and is not expected to fail in any way that would prevent access to user data. The READY LED on the control panel must be ON when the disk array is operating online. The following table lists possible error conditions and provides recommended actions for resolving each condition. If you are unable to resolve an error condition, contact your HP representative, or call the support center for assistance.
