1.1.2 High Reliability and High Availability

 Key components such as controllers, cache memories, power supplies and fans are redundantly
configured.
 Cache data is dually written to controllers. Even if a controller fails, integrity of the data on the
caches of the other controller is maintained.
 Data on caches is automatically saved in the internal flash memory by using the battery power
when a power outage occurs.
 The disk array supports RAID-1,5, 6, 10, 50, 60, and TM by default. Even if a disk drive fails,
operation can be continued without causing data loss.
Multiple hot spare disks can be configured.

1.1.3 Operation Management

NEC Storage Manager allows for basic configuration settings, status display and status monitoring
easily. NEC Storage Manager Suite program product, which needs to be purchased separately, allows
