Type. The drop-down list lists the possible RAID configurations for the drives selected in the list of Available Drives. Available configurations may include RAID 0, RAID 1, RAID 5, RAID 10, Single Disk, and Spare Disk. For information about these configurations, see “Available RAID Configurations” on page 7.

Name. You can enter a name for the unit.

Stripe. The drop-down list of stripe sizes lists the possible stripe sizes for the configuration you selected in the RAID level drop-down.

The default stripe size of 64KB will give the best performance with applications that have many sequential reads and writes. A larger stripe size will give better performance with applications that have a lot of random reads and writes. In general, the smaller the stripe size, the better the sequential I/O and the worse the random I/O. The larger the stripe size, the worse the sequential I/O and the better the random I/O.

Write Cache, Auto Verify, and Continue on Source Error during Rebuild. These check boxes let you set the policies for the unit. These policies can also be set and changed on the Controller Settings page. For details about these policies, see “Unit Policies” on page 94.

Note: If the configuration window disappears while you are selecting drives, 3DM 2 may have refreshed. Click Create Unit again. If desired, you can reduce the frequency with which information refreshes in 3DM 2, or disable refresh temporarily, on the 3DM 2 Settings page.

StorSave. You can specify the StorSave Profile to be used for the unit. Three profiles are available: Protection, Balanced, and Performance. For more information, see “Setting the StorSave Profile for a Unit” on page 48.
