Getting Started
In order to setup the ICP RAID controller, follow the instructions in the sections below to:
•
Determine your RAID level and array configuration
•
Create a RAID driver installation diskette
•
Install the controller
After completing these steps, refer

Determine the RAID Configuration

Begin the installation by completing the worksheet in
level, the number of disk drives, and the disk drive size for your system. Refer to
1.3, RAID Levels
RAID level solution for your needs.

2. In column 2, note the number of disk drives supported for the RAID level you
selected.
3. In column 3, record the number of disk drives you will use for the host drive.
4. In column 4, record the capacity, in megabytes (MB), that you will need on each
physical drive.
You will enter this value as the "Used Capacity per Drive" when you are creating the
host drive. Based on the physical drive capacity value and the number of disk drives
you will use, the RAID configuration software will calculate the total host drive size
for your selected RAID level.
The capacity of the smallest drive in the initial RAID array configuration becomes the
maximum capacity that the RAID configuration software can use for each hard disk in the
host drive. This becomes important when you configure an array with hard disks of
potentially varying sizes and you want to ensure that future drives added to the disk array
will fit in the array (for example, for replacement purposes). Should a new drive have less
than the physical drive capacity used for each disk in the existing disk array, the RAID
configuration software could not accept the new drive.
