5-26Running the Array Configuration Utility

Create Logical Drive Screen

In this screen, you can select the fault-tolerance method, enable the array accelerator, set the logical drive size, and set the stripe size.

NOTE: Given the reliability of a particular generation of hard drive technology, the probability of an array experiencing a drive failure increases with the number of drives in an array. Compaq recommends the number of drives in an array be limited to 15.

Figure 5-22. Create Logical Drive screen

The Logical Drive Size area includes a scale marked with the amount of drive capacity available for a logical drive. The utility does not allow you to create a logical drive larger than the maximum supported by the operating system.

The left side of the Logical Drive Size scale indicates the amount of space available for data. The right side of the scale indicates the amount of space required for storing parity or mirrored information, depending on the fault- tolerance method. This is needed only for RAID 1, RAID 4, or RAID 5.
