Understanding logical drive configuration
When you create an array, you group
hard disk drives into one storage area. You can define this storage area as a
single logical drive, or you can subdivide it into several logical drives. Each
logical drive appears to the operating system as a single physical hard disk drive.
The ServeRAID controller supports up
to eight logical drives. If you have only one array, you can define it as a single
logical drive, or you can divide it into several logical drives. Typically, the
first logical drive that you define will be your startup (boot) drive. If you
have two or more arrays, each array can be one logical drive, or you can divide
each array into multiple logical drives, as long as the total number of logical
drives for all of the arrays does not exceed eight.
If you do not define a logical drive
for every array, the ServeRAID Manager will define a logical drive with the largest
capacity and highest RAID level possible.
Note:
Refer to the documentation provided with your operating system for information
about the recommended logical-drive sizes.
Limitations to consider:
- You can have up to eight arrays
on a controller.
- You can have up to eight logical
drives on a controller.
- If any existing logical drives
are defined as RAID level-5 Enhanced, you can only have seven logical drives
on a controller.
