5. Press any key to return.
Now that an array has been defined, it is necessary to create the logical drives
on this array. Logical drive definitions for created arrays must be done before
exiting the Create/Delete Array menu.
Notes:
1. Up to four arrays can be defined per controller.
2. An array can be defined across the two channels of one controller.
3. You cannot define an array across two controllers.
4. For maximum performance and configuration flexibility, all installed drives
should be configured into a single-disk array. Where data separation is
desired, use separate logical drives on the same disk array. Each of these
logical drives will appear as a separate physical disk to software programs
like FDISK, and may be further divided into logical partitions. With this
approach, if additional physical drives are added at a later date, they can be
easily added as a second array without reconfiguring the original drives.
