4.5.3.7 Using Manual
Configuration: RAID 50
RAID 50 provides the features of both RAID 0 and RAID 5. RAID 50 uses both distributed
parity and drive striping across multiple drive groups.
It provides high data throughput, data redundancy, and very good performance. It is
best implemented on two RAID 5 drive groups with data striped across both drive
groups. Though multiple drive failures can be tolerated, only one drive failure can be
tolerated in each RAID 5 level drive group.
RAID 50 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 group.
1. Hold <Ctrl> while selecting at least three ready drives in the Drives panel on the left.
