Recommended RAID Levels:

–

PERC 4/DC, 4e/DC, 4/Di, and 4e/Di Controllers

—It is

recommended that you only use RAID 10 or RAID 50.

Complete Create Virtual Disk Advanced Wizard (Step 2 of 4). In this step,

you select the channels and the disks to be used by the virtual disk. The

selections you make determine whether or not the virtual disk is channel-

redundant.

There are specific RAID level and configuration requirements for

implementing channel redundancy. You must select the same number of

physical disks on each channel that you use. For information on the

number of physical disks that can be used for different RAID levels, see

Number of Physical Disks per Virtual Disk. For information on controller-

specific implementations of the RAID levels, see Controller-supported

RAID Levels.

To complete Create Virtual Disk Advanced Wizard (Step 2 of 4), see

Physical disk Selection for Channel-redundant Virtual Disks on PERC

4/DC, 4e/DC, 4/Di, and 4e/Di Controllers depending on the type of the

controller.

Physical disk Selection for Channel-redundant Virtual Disks on PERC 4/DC,

4e/DC, 4/Di, and 4e/Di Controllers

The following sections describe creating a channel-redundant virtual disk

using RAID 10 or RAID 50 on a PERC 4/DC, 4e/DC, 4/Di, or 4e/Di,

controllers.

RAID 10

Select one physical disk on each of two channels. (In other words, each

of the two channels select a single disk.)

Select an additional disk on each of the two channels. You have now

selected the minimum number of disks for a RAID 10.

Repeat step b until you have the desired number of disks.

RAID 50

Select one physical disk on each of three channels. (In other words,

each of the three channels select a single disk.)
