Note: Multiple arrays can be created using the same set of hard disk drives. The Capacity option
allows you to set aside disk space that be used to create another array or set as a spare disk.

press ENTER.
Single RAID – Cross Adapter
The term “Single RAID – Cross Adapter” refers to the RocketRAID 2220 ability to create RAID arrays
between drives attached to multiple RocketRAID 2220 Adapters. Each RAID array can support up to 16
hard disks, and these disks can be attached to as many as 4 separate RocketRAID 2220 adapters.
Cross-Adapter arrays are created in the same manner as standard arrays. The BIOS utility menu will
display disks attached to each RocketRAID 2220 adapter installed into the system. Use the Page Up and
Page Down keys to scroll through available hard disks.
3 - Adding/Removing Spare Disks
This command is used to assign a hard disk to act as a Spare Disk.
Spare Disks are used to automatically rebuild Redundant RAID arrays (RAID 1, 5, 10) in the case of disk
failure. To set a hard disk to act as a Spare Disk, use the ↑ ↓ arrow keys to select a disk, and press ENTER.
To remove the Spare Disk setting from a hard disk, highlight the spare disk, and press ENTER.
Generally, single disks are designated to act as spares (disks that are not configured into RAID arrays).
However, in some instances, disks that are members of RAID arrays may also be designated to act as a
spare. If the disks in question are part of a RAID array that did not utilize the full available capacity at the
time of creation, these disks may be used as spares.
For example: a RAID 0 array was created between two 200GB hard disks, but only 200GB of space (out of
a grand total of 400GB), was assigned to that array. In this example, 200GB of disk space remains
unallocated. This unallocated space would allow these disks to be set as spares for a separate redundant
array that falls into the same capacity range (200GB).
