Dynamic Cross Call Feature
The disk array unit is equipped with two array controllers to enable dynamic cross call
control. In the configuration, the two array controllers can access to all logical disks by
turning on cross call feature (factory-set is off). If either of the array controllers is
defected, the disk array unit can continue the operation by using the remaining array
controller. Setting can be changed by using management software.
In order to use this feature, middleware is required as well as OS.
To view the resources of the disk array unit through the host computer in real time, use the
disk array unit management software "NEC Storage Manager" of "NEC Storage
BaseProduct Ver 2.1 - NEC Storage S2300" (separately priced) that is used with the disk
array unit. NEC Storage Manager also enables you to set the following parameters
through the host computer:
• Setting of RAID configuration (RAID0, 1, 5, 10, and hot spare disk)
• Resetting of RAID configuration
• Setting of various features such as cross-call mode
• Collection of error log
To use the disk array unit, you need to purchase "NEC Storage BaseProduct
- NEC Storage Ver2.1 2300" sold separately.
Before the disk array unit can be used, the license lock must be released by
using the license code provided with NEC Storage BaseProduct.
Be sure to release the license lock. A disk array unit without the license lock
being released cannot receive any maintenance services because the
operation cannot be guaranteed.
