    2 Hardware description of the HP XP24000/XP20000 Disk Array The HP StorageWorks XP series of disk arrays are high-performance RAID-capable disk array systems used to store large quantities of data in an efficient and secure manner. There are no single points of failure in the disk arrays. They include redundant logic assemblies, controllers, power supplies, and dual-ported RAID disk drives, all of which can be removed or replaced without interrupting access to data.

  • Page 22: Xp20000 System Architecture

    Figure 2 XP24000 system architecture XP20000 system architecture Figure 3 shows, the basic XP20000 disk array consists of three main sections: the power supply, a DKC, and a DKU. The power supply section consists of the AC-DC power supplies and battery boxes. The DKC consists of the channel adapters (CHAs), disk adapters (DKAs), cache memory adapters (CMAs), and shared memory adapters (SMAs).

  • Page 23: Physical Assemblies

    Figure 3 XP20000 system architecture Physical assemblies The XP24000 disk array includes the following major hardware assemblies (see Figure One disk control frame (DKC) Zero to four disk array frames (DKUs) To monitor and manage the array, a management server supplied by the customer is also required. The following figure shows the disk array with the maximum of four DKUs.

  • Page 24: Disk Control Frame

    Disk control frame The DKC controls the disk array. It contains the control panel, connection hardware, power supplies, SVP, and control boards for the disk array. It also contains up to 128 disk drives for the XP24000 and contains up to 120 disk drives for the XP20000. DKC clusters As the following figure shows, power and PCBs in the DKC are organized into two independent and redundant clusters.

  • Page 27: Backup Batteries

    Figure 8 Intermixed RAID groups Backup batteries The XP24000/XP20000 disk arrays use batteries and two modes of backup operation to provide backup power protection for cache memory, shared memory, the DKAs, CHAs, and disk drives. If AC input power is lost, the disk array continues normal operation for 200 ms or 1 minute, depending on whether the disk array is set for Backup Mode or De-stage Mode.

  • Page 28: Operating Specifications

    Figure 9 Battery de-staging and backup modes When AC power is restored, the disk array powers on again automatically if the AUTO POWER-ON jumper is set to ENABLE. If the jumper is set to DISABLE, the disk array must be manually powered on again using the control panel PS ENABLE and PS ON/OFF switches.

  • Page 40: Powering Down The Disk Array

    Item Label Indicator Description During normal operation, this LED should be on. ON: The disk array is plugged in and receiving power from the primary AC outlet. The SVP is receiving BS-ON power from the outlet. LED (Amber) OFF: The disk array is not receiving power from the primary AC outlet.

  • Page 41: Planned Power Off

    Planned power off Occasionally, you may need to plan a site power outage, such as during alterations to the data center, inspections, or work by the electric company. If a scheduled power outage will affect the disk array, contact your HP support representative to schedule a planned power off. CAUTION: Only a trained HP support representative can shut down and power off the disk array.

  • Page 42: Recovering From An Unplanned Power Outage

    Pull the switch up and then out towards you. The disk array shuts down immediately. The UNIT EMERGENCY POWER OFF switch mechanically locks itself in the off position to prevent anyone from restoring power in a potentially hazardous situation. WARNING! The UNIT EMERGENCY POWER OFF switch provides only partial power off capability.

  • Page 43: Automatic Restart When Power Is Restored

    Move the PS ON/OFF switch to the ON position. The following LED power sequence occurs: BS-ON turns amber. PS-ON turns green. SUB-SYSTEM MESSAGE may turn amber if the disk array is not configured for remote support. This indicates the system has produced a service information message because of the power outage.
