Getting Started Getting Started 2 2.1 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 Chapter 3 for quick installation instructions. For more detailed instructions refer to the other installation chapters (Chapter 4 through Chapter 9). Determine the RAID Configuration Begin the installation by completing the worksheet in Table 2-1 to determine the RAID level, the number of disk drives, and the disk drive size for your system. Refer to Section 1.3, RAID Levels for more information about RAID levels and to determine the optimum RAID level solution for your needs. 1. In column 1 of Table 2-1, select a RAID level. 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. 24 Software Installation and User's Guide
