◊ No: Leave background initialization enabled. This means that a new
configuration can be initialized in the background while you use
WebBIOS to do other configuration tasks. This is the default.
◊ Yes: Select Yes if you do not want to allow background initializations
for configurations on this controller.
• Select Size: Specify the size of the virtual drive in terabytes, gigabytes,
megabytes, or kilobytes. Normally, this would be the full size for RAID 6
shown in the Configuration panel on the right. You may specify a smaller
size if you want to create other virtual drives on the same drive group.
8. Click Accept to accept the changes to the virtual drive definition, or click
Reclaim to return to the previous settings.
9. Click Yes to confirm the write policy mode you have chosen.
10. Click Next when you are finished defining virtual drives. The configuration

Using Manual Configuration: RAID 60
RAID 60 provides the features of both RAID 0 and RAID 6, and includes both parity
and drive striping across multiple drive groups. RAID 6 supports two independent
parity blocks per stripe. A RAID 60 virtual drive can survive the loss of two drives in
each of the RAID 6 sets without losing data. RAID 60 is best implemented on two
RAID 6 drive groups with data striped across both drive groups. Uses 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 drive capacity is available. Two drive failures can be tolerated in
each RAID 6 level drive group.
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 Manual Configuration and click Next, the Drive Group Definition
screen appears. You use this screen to select drives to create drive groups.
1. Hold <Ctrl> while selecting at least three ready drives in the Drives panel on
the left.
