Many factors affect battery life, including length of storage time, length of operating time, storage temperature, and operating temperature. A battery should be replaced if the BATTERY LEDs or the software indicate a battery has diminished storage capacity.
  • Page 27 A new disk can be added at any time, even while the array is operating. When a disk is replaced, the array applies power to the disk in a controlled manner to eliminate power stresses. The array controller will recognize that a new disk has been added and, if the Auto Include feature is enabled, will include the disk in the array configuration automatically.

  • Page 28: Disk Drive Filler Panels

    If an image disk fails on the VA 7100 or VA 7400, the array will operate with a single image disk until the failed disk is replaced. If an image disk fails on the VA 7410, the backup image disk will be used, maintaining image disk redundancy.

If the power fails or if you unplug the power cords without performing a shutdown, the following sequence will occur when the array is powered on again: The array will attempt to retrieve the maps from cache and determine if they are valid.

  • Page 38: Data Storage Process

    Data Storage Process Virtual Array The term “Virtual Array” refers to the way the array manages the disks as a pool of data storage blocks instead of whole physical disks. Like other virtualization within computer systems, this virtualization greatly simplifies the management of the array.

  • Page 39: Redundancy Groups

    Figure 12 Virtual Data Storage Storage Cache Pool Maps LUN 1 Host LUN 2 Redundancy Groups Array physical capacity is divided into Redundancy Groups. A Redundancy Group (RG) can be thought of as an independent array. Each RG has its own set of disks, active hot spare, and controller.
  • Page 40 high-performance disks, and the other RG from large, slower, high- capacity disks. The VA 7100 and VA 7400/7410 differ in their implementation of redundancy groups. VA 7100/7110 Redundancy Group The VA 7100 and VA 7110 each have one redundancy group (RG1). See Figure 13 Figure 14.

  • Page 42 VA 7400/7410 Redundancy Groups The VA 7400 and VA 7410 have two redundancy groups (RG1 and RG2). See Figure 15 Figure Controller 1 manages Redundancy Group 1 (RG1), which consists of all ■ disks in odd numbered slots (D1, D3, D5, D7, D9, D11, D13, D15) in the controller enclosure, and in all disk enclosures (JA0-JA5).

  • Page 45: Performance Path

    Performance Path The performance path is the most direct path from the host to the data in the array. It is specified by two separate device files that direct the data either through Controller 1 or through Controller 2. The performance path is always the faster path in terms of data transfer rate.
  • Page 46 VA 7400/7410 Performance Path The following example illustrates how the performance path is used in a VA 7400/7410: Assume LUN 4 is part of Redundancy Group 2 under Controller 2. An HP-UX host has two device files that have two separate paths to LUN 4: The primary device file that addresses Controller 2, and the secondary device file that addresses Controller 1.

  • Page 47: Raid Levels

    RAID Levels Redundant Array of Inexpensive Disks (RAID) technology uses different industry-standard techniques for storing data and maintaining data redundancy. These techniques, called “RAID levels”, define the method used for distributing data on the disks in a logical unit (LUN). LUNs that use different RAID levels can be created in the same array.
  • Page 48 Upon completion of the rebuild of a failed disk, the array is once again protected against any single disk failure. Note RAID groups with an even number of disks will always have a single adjacent disk after a disk failure, and RAID groups with an odd number of disks will always have two adjacent disks after a disks failure.
  • Page 49 simultaneous disk failures. The two redundancy segments are referred to as “P” and “Q” parity. P, like traditional RAID 5 arrays, uses an XOR (parity) algorithm. P parity is based on Reed-Solomon ECC technology, similar to error detection and correction found in ECC DRAM. Application data, and the P and Q parity data, rotate to different disks for each stripe in a RAID Group.
  • Page 50 Figure 19 RAID 5DP Data Storage Example Data Availability and AutoRAID When configured in the AutoRAID mode, the Virtual Array uses a combination of RAID 1+0 and RAID 5DP. As a result, the disks within a single RG can have a portion of its data capacity used as RAID 1+0, while the other portion is used as RAID 5DP.
  • Page 51 continuous high demand from the host will preempt all data migration activities. AutoRAID manages the data placement to the individual 256 K-block. Each LUN is divided into 256 K-blocks call clusters. A cluster can be stored in either RAID 1+0 or RAID 5DP format. The virtualization data structures manage the translation of the logical address (LUN) and the physical location.

  • Page 52: Data I/O Architecture

    Data I/O Architecture The internal architecture of the array controllers is designed to optimize the speed of data transfer between the array and the host. The internal architecture for each product is illustrated in Figures 20, 22, and 23. The following major components are involved in the flow of data through the array: Data flow processor - manages movement of data over the internal high- ■...

    possibility of data loss in the event of multiple disk failures. Although the statistical advantage of this minimal but measurable, HP advises when ever possible to keep an even number of disks in each redundancy group. For optimum availability, it is recommended that you have an even number of disks in each redundancy group.
