  • Page 21: Hardware

    2 Hardware 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, disk drives, and power supplies, all of which can be removed or replaced without interrupting access to data.

  • Page 22: Physical Components

    Physical components The disk array includes the following major hardware components: • One disk control frame (DKC) • Zero to four disk array frames (DKUs) • One service processor (SVP) To monitor and manage the array, a Device Manager server is also required. The following figure shows the disk array with the maximum of four DKUs.

  • Page 23: Control Panel

    Control panel Once the disk array is powered on and running normally, no user operations are required at the control panel, except when instructed by your HP support representative. The following figure shows the control panel location and layout. The accompanying table explains the control panel functions.

  • Page 37: Operations

    3 Operations During normal operations, the disk array does not require your intervention and you should not attempt to open the disk array cabinets. The disk array reports any service information messages (SIMs) to the SVP and the Device Manager server. If the array is set up to “phone home,” the SVP automatically reports SIMs to the HP Storage Technology Center (STC).

  • Page 38: General Safety Guidelines

    General safety guidelines Carefully read these safety guidelines and follow them when working with the disk array. • Fully understand and follow all hazard warnings in this guide and on warning labels on the disk array. These hazard warnings help you to prevent or reduce the risk of death, personal injury, or product damage.
  • Page 39 CAUTION: If you detect any abnormal noise, smell, or smoke coming from the disk array, immediately power off the disk array by following the emergency power off procedure later in this chapter. For routine power off in non-emergency situations, contact your HP support representative. CAUTION: Do not power off the system unless it is an emergency situation and you follow the procedure for Emergency power off.

  • Page 40: Powering Down The Disk Array

    Powering down the disk array Two situations may arise when you need to power down the system: • Planned power off • Emergency 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.

  • Page 41: To Power Off The Disk Array In An Emergency

    To power off the disk array in an emergency: Locate the UNIT EMERGENCY POWER OFF switch on the back side of the DKC. Its location is shown in the following figure. Pull the switch up and then out towards you. The disk array shuts down immediately.

  • Page 42: Recovering From An Unplanned Power Outage

    Recovering from an unplanned power outage Unplanned power outages occur when the primary building power is lost due to electrical blackouts, thunderstorm activity, or similar occurrences, and input AC power is not received by the disk array. The disk array will maintain its state and recover when power is restored.

  • Page 43: Automatic Restart When Power Is Restored

    Automatic restart when power is restored CAUTION: As with all sophisticated electronic equipment, unstable power conditions during a restart can cause problems. HP recommends automatic power on restart only if the power to the disk array is subject to power conditioning equipment, such as a UPS, to ensure that the power restored to the disk array is stable.

    Glossary Array control processor. On some XP models, such as the XP12000, the ACP handles the passing of data between the cache and the physical drives. On other XP models, such as the XP10000, this function is handled by the disk adapter on the MIX board.
  • Page 74 The benefit of cache memory is that it speeds I/O throughput to the application. The larger the cache size, the greater the amount of data buffering that can occur and the greater throughput to the applications. XP arrays support a range of cache memory. In the event of power loss, battery power holds up the contents of cache for up to 36 hours.
