Phoenix technology to prevent

business operations being interrupted

This technology first isolates the disk drive where a response

delay has occurred, and automatically checks this isolated

disk drive. If no problem is found, the isolated disk is restored

to the original RAID configuration, minimizing the chance of

switching to the hot spare disk. This technology also minimizes

the delay in accessing from a server, because a disk drive where

a response delay occurs is isolated temporarily, and other disk

data in the RAID is used to continue processing.

Replication functions

NEC S Series storage can satisfy a variety of needs including

high-speed disk backup as well as low-cost backup with its full

suite of replication functions.

Low-cost backup/archive by

■

mixture of FC/SATA disk drives

S2900/S2500/S1500 supports large capacity, low cost SATA

disk drives as well as FC disk drives. FC disk drives for core

business operations which require non-stop operation and high

performance, and SATA disk drives for backup which requires

large capacity and low cost. Both kinds of disk drives can be

installed in a single disk array unit.

Security access control

■

Access to individual logical disks can be controlled. Write

access can be restricted from any server providing for complete

security and integrity of data.
