ASUS PIKE 1078 2-27
Using Custom Configuration: RAID 60
RAID 60 provides the features of both RAID 0 and RAID 6, and includes both
parity and disk striping across multiple arrays. RAID 6 supports two independent
parity blocks per stripe. A RAID 60 virtual disk can survive the loss of two disks in
each of the RAID 6 sets without losing data. RAID 60 is best implemented on two
RAID 6 disk arrays with data striped across both disk arrays. Use RAID 60 for data
that requires a very high level of protection from loss.
RAID 60 can support up to eight spans and tolerate up to 16 drive failures, though
less than total disk drive capacity is available. Two drive failures can be tolerated in
each RAID 6 level array.
RAID 60 is appropriate when used with data that requires high reliability, high
request rates, high data transfer, and medium to large capacity.
When you select Custom Configuration and click Next, the Disk Group Definition
