Create Legacy RAID Group

This menu option is disabled if new RAID groups exist. If enabled, this menu option displays a dialog box to create

a legacy RAID group. Enter values for the following parameters.

Parameter Description

RAID Group

Select a group ID from the available ID list. The maximum number of Legacy RAID

Groups is limited to the number of hard drives that are connected to the RAID controller.

Configuration

Select one of:

• Striped (for RAID 0)

• Mirrored (for RAID 1)

• Mirrored Striped (for RAID 10)

• Parity RAID (for RAID 5)

Capacity

Select from a list of RAID group sizes. Options include sizes from 256 MB to 100 GB, plus

MAX.

Chunk Size

Select a value from the available list to define the chunk size (stripe size) for performance

tuning: 8, 16, 32, 64, 128 (KB). Mirrored (RAID 1) does not require a chunk size.

Rebuild

Priority

Select a value to identify how quickly the controller should rebuild data on a disk after a

hardware failure. A value of 1 is the lowest priority and will take the longest to rebuild. A

value of 10 is the highest priority and will rebuild the fastest, but may require more CPU

resources, which might affect the computer’s performance. Striped (RAID 0) does not use

this value.

Devices Select RAID member devices from the available device segment grid.
