    RAID Configuration The RAID configuration in the disk array unit can be used in the combinations shown in the table below. Table 1-1 Possible RAID Combinations RAID level RAID0 RAID1 RAID5 RAID10 Number of physical drives in configuration 1, 3, 5, 10, 2+1 to 14+1 2+2 to 7+7 Number of logical drives per subsystem 1,024 max.

  • Page 34: Logical Disk Capacity

    Logical Disk Capacity Arbitrary Logical Disk Capacity The management software (NEC Storage Manager) allows you to configure an arbitrary logical disk capacity. The capacity must be entered in MB (1MB=1024KB). To calculate the logical disk capacity, first define the striping unit using the following...

  • Page 35: Maximum Logical Disk Capacity

    The table below shows the maximum capacity per logical disk (including the system capacity of 2 MB). To obtain the value to be entered as the LD capacity in NEC Storage Manager, subtract the system capacity (2 MB) from the capacity indicated in the table below.

  • Page 36: Dummy Logical Disk

    Do not use the created logical disk as it is. After the OS recognizes the logical disk, be sure to unbind it by using the management software (NEC Storage Manager), and then bind it.

  • Page 37: Auto Repair Mode

    When an unused spare disk exists, you can specify whether the repair is automatically started or the system enters into repair wait mode and the repair must be started manually from the NEC Storage Manager (management software). The auto repair is enabled at the factory.

  • Page 38: Write Cache Feature

    Write Cache Feature In a RAID 5 configuration, the performance of the disk array unit may decrease during writing of small amounts of data. It is because the previous and parity data must be read to recalculate the parity. The disk array unit is equipped with cache memory. When write data is stored in the cache memory, the disk array unit terminates the command processing and then writes the data to disks for improving the performance.

  • Page 39: 1-Bbu Cache Enable Mode

    When only a single battery backup unit is installed, the write cache operation mode can be set using the management software (NEC Storage Manager). In this state, remember that if a fault occurs in the battery backup unit, the failed battery backup unit must be replaced with a new one immediately to avoid data loss.

  • Page 40: Cross Call Feature

    Cross Call Feature The dynamic cross call feature of the disk array unit can be set using management software (NEC Storage Manager). Off state of cross call feature (factory-set) In this state, the disk array unit is accessible from the host adapter (HBA) of the host system in which the logical disks (LDs) are bound (RAID configured).

  • Page 41: Initial Assignment Feature

    Initial Assignment Feature You can assign a logical disk (LD) to the controller on the path to which you bound that logical disk (built the RAID). When an attempt is made to access the logical disk from the unassigned controller, the error 05/04/00 ("illegal request - not assigned") is returned.

  • Page 42: Path Fail-Over Feature

    Expand LUN This feature increases the number of logical disks available from the host. On Windows NT/Windows 2000 and Solaris, the expand LUN feature is disabled (factory-set). The setting can be changed with NEC Storage Manager (management software). Note: When the disk array unit is connected to a basic...
  • Page 43 [Windows NT4.0] After logical capacity has been expanded, the host system must be rebooted to recognize the logical capacity expanded. [Windows 2000] If the LD is used as a basic disk and expanded, the host system must be rebooted to recognize the logical capacity expanded.

  • Page 44: Access Control Feature

    To use access control, the cross call feature must be enabled. Dedicated software (NEC Storage AccessControl for S1300), which must be purchased separately, is necessary for using the access control feature.
