Express Configuration provides a quick and easy path for
you to automatically configure the ServeRAID controller.
This choice creates the most efficient ServeRAID
configuration based on the number and capacity of the
Ready drives available in the system. If four or more
Ready drives of the same capacity are available, this
choice also will define a
hot-spare drive for the ServeRAID
adapter or controller. A hot-spare drive is a physical drive
that is defined for automatic use when a similar drive fails.
The Express Configuration choice groups up to 16 Ready
drives of the same capacity into one disk array and defines
one logical drive for each array. This choice defines the
size of the logical drive, based on the amount of free
space available, and it assigns the highest RAID level
possible, based on the number of physical drives available.
For example, if the server contains one 1024 MB Ready
drive, two 2150 MB Ready drives, and four 4300 MB
Ready drives, Express Configuration will create three
arrays and one hot-spare drive as follows:
Array A: The total capacity of this array is 1024 MB
(1 x 1024 MB) and it contains one 1024 MB
RAID level-0 logical drive.
Array B: The total capacity of this array is 4300 MB
(2 x 2150 MB) and it contains one 2150 MB
RAID level-1 logical drive.
Array C: The total capacity of this array is 12900 MB
(3 x 4300 MB) and it contains one 8600 MB
RAID level-5 logical drive.
Hot Spare: Express Configuration defines one of the four
4300 MB drives as a hot-spare drive, as
follows:
Ÿ
When there are four or more Ready
drives of the same capacity, Express
Configuration groups three of the drives
into one array (as in Array C) and
defines one of the drives as a hot spare.
Ÿ
A hot-spare drive must be of equal or
greater capacity than the drive that it is
intended to replace. In this
configuration, the 4300 MB drive can
replace any failed drives in Array B or
Array C.
