74 USC and USC-LCE Operations
•
RAID 6
— Stripes data across the physical disks, and uses two sets of
parity information for additional data redundancy. If one or two physical
disks fail, the data can be rebuilt using the parity information. RAID 6
offers better data redundancy and read performance but slower write
performance with very good data redundancy.
•
RAID 10
— Combines mirrored physical disks with data striping. If
a
physical disk fails, data can be rebuilt using the mirrored data. RAID 10
offers good read and write performance with good data redundancy.
•
RAID 50
—
A dual-level array that uses multiple RAID 5 sets in a single
array. A single physical disk failure can occur in each of the RAID 5 without
any loss of data on the entire array. Although the RAID 50 has increased
write performance, when a physical disk fails and reconstruction takes
place, performance decreases, data/program access is slower, and
transfer
speeds on the array are affected.
•
RAID 60
—
Combines the straight block level striping of RAID 0 with the
distributed double parity of RAID 6. Your system must have at least eight
physical disk to use RAID 60. Because RAID 60 is based on RAID 6,
two
physical disk from each of the RAID 6 sets could fail without loss
of
data. Failures while a single physical disk is rebuilding in one RAID 6
set
do not lead to data loss. RAID 60 has improved fault tolerance
because
more than half the number of total physical disk must fail for data
loss to occur.
•
Volume
— A single disk drive or segment without any RAID level or
redundancy.
