Learning about Custom Configuration
The Custom Configuration path allows you to manually configure
your ServeRAID subsystem. Using this path, you can select the
drives that you want to include in each array, define the number and
size of the logical drives for each array, and select the drives that
you want to use as hot spares.
Before you select the Custom Configuration path, consider the
following:

If you are not familiar with the IBM implementation of RAID
technology, you might want to review the information provided in
“Understanding RAID Technology” on page 5 before you begin.
Ÿ
Each ServeRAID controller supports a maximum of eight arrays.
Ÿ
Each ServeRAID controller supports a maximum of eight logical
drives.
When you create an array, you group hard disk drives into one
storage area. You can define this storage area as a single
logical drive, or you can subdivide it into several logical drives.
Each logical drive appears to the operating system as a single
physical hard disk drive.
If you have only one array, you can define it as a single logical
drive, or you can divide it into several logical drives. Typically,
the first logical drive defined on the first ServeRAID adapter or
controller found by the basic input/output system (BIOS) during
startup will be your startup (boot) drive.
If you have two or more arrays, each array can be one logical
drive, or you can divide each array into multiple logical drives, as
long as the total number of logical drives for all of the arrays
does not exceed eight.
Note: Independent of the RAID logical drives, most operating
systems allow you to partition the logical drives further.
