RAID Options
• 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. Does not
provide data protection.
• RAID 1 (drive mirroring): One or more drives duplicate one
drive for maximum data protection. Available only on
systems with two (2) or more drives.
• RAID 5 (drive striping with parity): For each array, the size
of one drive is reserved for parity. Provides good
performance and space utilization with one-drive fault
tolerance. Available only on systems with four (4) or more
drives.
• RAID 6 (drive striping with two parity drives): Like a RAID 5
except that two drives are used for parity rather than one.
Provides moderate performance and reasonable space
utilization with two-drive fault tolerance. Available only on
systems with four (4) or more drives.
• RAID 10 (striped mirroring): A combination of RAID 0 and
RAID 1. Provides high performance and fault tolerance.
Available only on systems with four (4) or more drives.
• Global or local hot spare support
• Instant Capacity Expansion (ICE): Logically groups RAIDs
for dynamic online scalability.
DHCP Support
Supports Dynamic Host Configuration Protocol (DHCP) for
