1 Introduction XP7 Storage overview XP7 Storage 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 XP7 Storage and its components.
Figure 3 XP7 disk drive rack dimensions 8 Introduction
Figure 4 Six Rack Configuration dimensions 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. It can be expanded with a high degree of granularity to a system offering up to twice the number of processors, cache capacity, host interfaces and disk storage capacity.

Figure 9 3.5 inch drive chassis Figure 10 Flash module drive chassis Features This section describes the main features of XP7 Storage.
Scalability XP7 Storage 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 192 2 1/2 disk drives, 96 3 1/2 disk drives, or 192 SSDs. Drives can be intermixed. See Table 2 (page 19) for details.
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: 16 • 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. • Two to four DKAs (each is a pair of boards).
• Hard Disk drive capacities of 300 GB, 600 GB, 900 GB , 1.2 TB, and 4 TB. • Solid State Disk Drive capacities of 400 GB, 800 GB. • Channel ports: 80 for one module, 176 for two modules. High performance The XP7 includes several new features that improve the performance over previous models. These include: • 8 GBps only Fibre Channel for CHAs without the limitation of microprocessors on each board. • SSD flash drives with ultra high speed response.
Non disruptive service and upgrades XP7 Storage is designed so that service and upgrades can be performed without interrupting normal operations. These features include: • Main components can be “hot swapped” — added, removed, and replaced without any disruption — while the disk array is in operation. The front and rear fan assemblies can be moved out of the way to enable access to disk drives and other components, but not both at the same time.

External Authentication and Authorization Storage management users of XP7 systems can be authenticated and authorized for storage management operations using existing customer infrastructure such as Microsoft Active Directory, LDAP, and RADIUS based systems.
2 Functional and operational characteristics System architecture overview This section briefly describes the architecture of XP7 Storage. Hardware architecture The basic system architecture is shown in the following diagram. Figure 12 XP7 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.
Array groups and RAID levels The array group (also called parity group) is the basic unit of storage capacity for XP7 Storage. Each array group is attached to both boards of a DKA pair over 2 SAS paths, which enables all data drives in the array group to be accessed simultaneously by a DKA pair. Each controller rack has two drive chassis (factory designation DKU), and each drive chassis can have up to 128 physical data drives. The XP7 supports the following RAID levels: RAID1, RAID5, RAID6.
configured as either 3390-x or OPEN-x logical devices. All LDEVs in the array group must be the same format (3390-x or OPEN-x). For open systems, each LDEV is mapped to a SCSI address, so that it has a TID and logical unit number (LUN). Figure 14 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.
Figure 15 LDEV striping across 2 RAID5 (7D+1P) array groups Figure 16 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 XP7 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 XP7 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 XP7 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 XP7 Storage 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 XP7 Storage has been installed, users can configure the disk array for mainframe operations.

• Command tag queuing • Industry-standard failover and logical volume management software • SNMP remote disk array management The XP7’s global cache enables any fibre-channel port to have access to any logical unit in the disk array. In the XP7, each logical unit 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.
Remote Web Console Remote Web Console is installed on a PC, laptop, or workstation. It communicates via a LAN to the SVP in XP7 Storage. The SVP obtains disk array configuration and status information and sends user initiated commands to the disk array. The Remote Web Console GUI displays detailed disk array information and allows users to configure and perform storage operations on the system.
3 System components Controller chassis The controller chassis provides system logic, control, memory, and monitoring, as well as the interfaces and connections to the disk drives and the host servers. The controller chassis consists of the following components: Table 14 Controller chassis Item Description Name Min Max CHA 2 8 if 4 DKAs installed. A CHA is an interface board that provides connection to 12 if no DKAs the host servers. It provides the channel interface control installed.

An IMPL of the SSVP is executed. NOTE: When the SVP High Availability Kit is installed, and an SVP failover (SIM RC-7FF3xx) has occurred, first take action to resolve the SVP issue before performing an SSVP reset.
Mainframe hosts can specify special attributes (for example, cache fast write command) to write data (typically sort work data) without write duplexing. This data is not duplexed and is usually given a discard command at the end of the sort, so that the data will not be destaged to the drives. Data protection The XP7 is designed so that it cannot lose data or configuration information from the cache if the power fails.

Cache memory Your XP7 can be configured with up to 512 GB of cache memory per controller chassis (1 TB for a two-module system). Each controller chassis can contain from two to eight cache memory adapter boards. Each board contains from 8 GB to 64 GB. Cache memory adaptor boards are installed in pairs and work together to provide cache and shared memory for the system. Each pair is called a cluster. From one to four cache clusters can be installed in a controller.

4 Power On/Off procedures Safety and environmental information CAUTION: Before operating or working on XP7 Storage, read the safety section in the HP XP7 Site Preparation Guide and the environmental information in “Regulatory compliance notices” (page 91). 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.
Battery backup operations The XP7 is designed so that it cannot lose data or configuration information if the power fails. The battery system is designed to provide enough power to completely destage all data in the cache if two consecutive power failures occur and the batteries are fully charged. If the batteries do not contain enough charge to provide sufficient time to destage the cache when a power failure occurs, the cache operates in write through mode.
When the batteries are connected and the power is off, the batteries slowly discharge. They will have a charge of less than 50% after two weeks without power. When fully discharged, the batteries must be connected to power for three hours to fully recharge. NOTE: The disk array generates a SIM when the cache destage batteries are not charged to at least 50%. The LEDs on the front panel of the cache boards also show the status of the batteries.
5 Troubleshooting Solving problems XP7 Storage 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.
