# Creating logical drives

Note: The ServeRAID-7t and ServeRAID-8i firmware supports a maximum of 10 "logical slices" per physical drive.

Complete the following steps to create logical drives:

1. In the Physical devices view (on the right), click the drives you want the logical drive to use. To view available segments on each disk drive, switch to the full-size capacity view or relative-size capacity view.
   Note: A segment shaded in light blue and outlined by a dashed line is not part of any logical drive.
2. To select a hot-spare for the logical drive, or to deselect a hot-spare, control-click the drive.
3. In the Name field, enter a name for the logical drive.
4. If you do not want to use the maximum size for the logical drive, click Advanced settings; then, type the size in the Size (MB) field:
   For HostRAID controllers, the logical drive uses all of the space on each disk drive; you cannot adjust the logical drive size.
5. To configure the logical drive for optimal performance, adjust the advanced settings as needed.
   Note: The default settings usually are adequate for most applications.
6. If you have free space available and want to create additional logical drives, click ; then, repeat steps 1-4.
7. When you are ready to continue, click Next. The "Configuration summary" window opens.
