7.5 Arrays & Logical Drives
At the top of the right column of the Summary tab is the Arrays & Logical Drives box. This
box shows how many Arrays and Logical Drives are configured on your system (Figure 7-13).
An Array is a set of physical disk drives that the controller groups together to provide one or
more logical drives to the host or host group.
While creating an Array, you can also choose the array’s RAID level; for more details about
the RAID levels, refer to 3.3.2, “Understanding RAID types” on page 50. Depending on your
configuration, this affects the system’s fault tolerance and performance. The bottom part of
the box shows which RAID levels are configured on your storage subsystems, how many
Arrays of this level exist, and how many Logical Drives are in each level.

7.6 Information Center
At the right bottom edge of the Summary tab is the Information Center box (Figure 7-14). It
includes several links to help you understand and set up your storage subsystem, as well as
answering any questions you can have.

displayed in this box also for Arrays with more than two disk drives, it means for RAID10.
