In this example, each array was created using drives from the same SCSI port. You
can get better performance by installing the correct capacity drives in other ports
before running the ACU, and then selecting drives from more than one port to build
the array.
Creating One or More Logical Drives on the Array
1. Select Array A or Unused Space under Array A in the Logical Configuration
View window (Figure 7-16).
2. Click Create Logical Drive in the Array box.
3. On the Create Logical Drive screen (Figure 7-11), select RAID 5.
4. Click Enable Array Accelerator, if it is active.
5. Change the stripe size, if desired (and if possible for your controller model).
6. The default values in the Logical Drive Size box will create a single logical drive
on the array. For this example, accept the default values.
7. Click Done to return to the ACU Main Configuration screen.
8. Save the new settings by clicking Controller on the menu bar and selecting Save
Configuration.
9. Create a logical drive on Array B by selecting Array B or Unused Space under
Array B in the Logical Configuration View window and following the previous
steps. This time, select RAID 1 as the fault tolerance method. Save the
configuration as before.
The ACU Main Configuration screen now looks like Figure 7-17.
