You can use the Configuration wizard to create up to eight arrays and up to eight
logical drives for each ServeRAID controller. The Configuration wizard provides two
configuration options: Express and Custom. Express configuration automatically
configures your ServeRAID controller, and you can use Custom configuration to
configure your controller manually. If you want to use RAID level-1E, RAID-level-5E,
or RAID level-x0, you must use Custom configuration. For more information about
RAID levels, see Chapter 3, “Understanding RAID technology” on page 21.
Using Express configuration
Express configuration automatically configures your ServeRAID controller. This
feature does the following:
v Creates arrays by grouping together same-sized physical drives.
v Creates one logical drive per array.
v Assigns a RAID level based on the number of physical drives in an array:
– An array with a single physical drive is assigned RAID level-0.
– An array with two physical drives is assigned RAID level-1.
– An array with three or more physical drives is assigned RAID level-5.
v Designates a hot-spare drive for the controller. If one or more arrays has four or
more physical drives, the largest-sized drive from those arrays is designated the
hot-spare drive.
Complete the following steps to use Express configuration:
1. In the ServeRAID Manager tree, click the ServeRAID controller that you want to
configure.
2. Click Express configuration .
3. Click Next . The “Configuration summary” window opens.
