RAID 60 Arrays
Note:
RAID 60 is an upgrade feature; if the RAID 60 feature is locked,
see
Adding Enhanced Features on page 20
for information on purchasing
a feature key.
Similar to a RAID 50 array (see
), a RAID 60 array is built from
eight disk drives configured as two or more RAID 6 arrays, and stripes
stored data and two sets of parity data across all disk drives in both
RAID 6 arrays.
Note:
Because the Adaptec 2420SA RAID controller can’t support more
than four disk drives, it can’t support RAID 60 arrays.
Two sets of parity data provide enhanced data protection, and striping
improves performance. RAID 60 arrays also provide high data transfer
speeds.
