Array Groups
The tool bar at the top of the Logical Configuration View window,
shown in Figure 3-4, contains the following buttons:
You can use the Logical Configuration View window to create any
combination of RAID level 0, 1, or 5 disk arrays. RAID 0 arrays can
be any combination of individual drives. RAID 1 arrays are
comprised of multiple pairs of drives. RAID 5 arrays contain three
or more drives.
One or more arrays of the same RAID level can be combined into a
multilevel RAID, such as:
■ RAID 10 for multiple RAID 1 arrays
■ RAID 50 for multiple RAID 5 arrays
The drives in a multilevel RAID appear as a single LSU to the host
computer.
Although arrays must be built from drives that are all attached to
the same controller, arrays can contain drives from multiple
channels. Arrays are built using the drives in the order selected,
regardless of which channel they are connected to.
Arrays created using drives on multiple channels can offer
performance benefits over single-channel arrays. Multiple channels
can also be used to create fault-tolerant arrays using pairs of drives
on alternate channels.
Switch View Switches to the Logical Information View. For
more information, see page 3-20.
Create Array Group Starts the process of collecting available
individual drives to assemble into a RAID array.
