RAID options 5

RAID options

RAID 0

RAID 0 offers the full capacity of the IO Accelerator without any disk-level redundancy.

NOTE: Windows® Software RAID configurations with IO Accelerators have not demonstrated

performance deterioration. Due to the high performance potential of the IO Accelerators,

physical RAID controllers are discouraged since they might become a performance bottleneck.

RAID 1

RAID 1 offers half the raw capacity with disk-level redundancy.

RAID 5

HP does not recommend configuring IO Accelerators in RAID 5 because of the parity calculations

required to manage the RAID 5 array.

RAID 10

You can use Symantec Storage Foundation to configure RAID 10 with IO Accelerators.

• You must have a minimum of four IO Accelerators.

• For more details, request the Symantec Storage Foundation Configuration Guide from your HP

representative.
