RAID Level 10 is used in applications requiring high performance and redundancy, combining the attributes of RAID Levels 1 and 0.

The QuickRAID10 command, accessed through the Command Line Interface, allows a simple, out-of-the-box setup of RAID Level 10 groups.

The array will operate in degraded mode if a drive fails unless you have enabled Hot Spare sleds.

RAID Level 5

RAID Level 5 increases reliability while using fewer disks than mirroring by employing parity redundancy. Distributed parity on multiple drives provides the redundancy to rebuild a failed drive from the remaining good drives. Parity data is added to the transmitted data at one end of the transaction, then the parity data is checked at the other end to make sure the transmission has not had any errors.

In the array, transmitted data with the added parity data is striped across disk drives. A hardware XOR engine computes parity, thus alleviating software processing during reads and writes.

The array will operate in degraded mode if a drive fails unless you have enabled Hot Spare sleds.

Interleave

The interleave size sets the amount of data to be written to each drive in a RAID group. This is a tunable parameter which takes a single stream of data and breaks it up to use multiple disks per I/O interval.

The CLI command RAIDInterleave allows you to change the size of the sector interleave between RAID groups. The value will depend upon the normal expected file transfer size. If the normal

file transfer size is large, the interleave value should be large, and vice versa.

The value entered for the RAIDInterleave command refers to blocks of data: one block is equivalent to 512 bytes of data.

Valid entries are 16, 32, 64, 128, 256 and SPAN. SPAN, not available in RAID Level 5, indicates that interleave size between the drives in the group will be the minimum drive size of all members in the group.

Hot Spare sleds

In most configurations, if a member of a virtual device becomes degraded, you must swap out the faulted sled as defined in Hot Swap Operating Instructions on page 71. If you have not enabled AutoRebuild, you must also start a manual rebuild.

For four configurations, however, Hot Spare sleds may be designated as replacements for faulted sleds without intervention by you or a host.

Each configuration requires a certain number of Hot Spare sleds. These sleds, once designated as Hot Spares, are not available for other use.

The following configurations will support optional Hot Spare sleds

RAID Level 1: 2 Hot Spare sleds

RAID Level 10: 1 group, 2 Hot Spare sleds

RAID Level 5: 1 group, 1 Hot Spare sled

RAID Level 5: 2 groups, 2 Hot Spare sleds
