RAID Options
The Snap Server 520 can be configured for
enhanced performance or maximum file
protection. Options include:
•
RAID 5 (drive striping with parity): For each
array, the size of one drive is reserved for
parity. Provides the best combination of
performance and data protection.
•
RAID 1 (drive mirroring): One or more drives
duplicate one drive for maximum data
protection.
•
RAID 0 (drive striping): Large virtual drive with
data striped across all drives of the array to
provide maximum performance with no loss in
usable capacity.
•
Global hot spare support.
•
Instant Capacity Expansion (I.C.E.) logically
groups RAIDs for dynamic online scalability.
•
RAID 1/5 background scanner constantly
monitors for disk media errors and if it’s
possible to repair the error, automatically
rewrites the “marginal” block.
