NFP Storage Manager 1.1 User's Manual
RAID 5 Cache
In supporting RAID 5, save/retrieval activity requires data in multiple
hard disk read/write to compute parity to maintain data security. To
improve read/write performance, NASolution Network Filer Plus
supports RAID 5 device-layer cache and data can be stored in
memory temporarily, thus is much faster than hard disk read/write
activity.
However, this function requires battery-backup memory
(SDRM or NVRAM) or UPS to be effective for any unanticipated
power failure that may result in data loss.
System administrator has to reboot NP1040 system to make RAID 5
Cache setting effective, and it will be applied only to the selected
volume(s).
