NF61S-M2 TE RAID 1: Every read and write is actually carried out in parallel across 2 disk drives in a RAID 1 array system. The mirrored (backup) copy of the data can reside on the same disk or on a second redundant drive in the array. RAID 1 provides a hot-standby copy of data if the active volume or drive is corrupted or becomes unavailable because of a hardware failure. RAID techniques can be applied for high-availability solutions, or as a form of automatic backup that eliminates tedious manual backups to more expensive and less reliable media. Features and Benefits ­ Drives: Minimum 2, and maximum is 2. ­ Uses: RAID 1 is ideal f or small databases or any other application that requires f ault tolerance and minimal capacity. ­ Benefits: Prov ides 100% data redundancy. Should one driv e f ail, the controller switches to the other drive. ­ Drawbacks: Requires 2 driv es for the storage space of one driv e. Perf ormance is impaired during driv e rebuilds. ­ Fault Tolerance: Yes.

RAID 1:
Every read and write is actually carried out in parallel across 2 disk drives in a RAID 1
array system. The mirrored (backup) copy of the data can reside on the same disk or on a
second redundant drive in the array. RAID 1 provides a hot-standby copy of data if the
active volume or drive is corrupted or becomes unavailable because of a hardware failure.
RAID techniques can be applied for high-availability solutions, or as a form of automatic
backup that eliminates tedious manual backups to more expensive and less reliable
media.
