Create Logical Drive Screen
In this screen, you can select the fault-tolerance method, enable the array
accelerator, and set the logical drive size.
Figure 5-20.
Create Logical Drive screen
The Logical Drive Size area shows a scale marked with the amount of drive
capacity available for a logical drive. The utility does not allow you to create a
logical drive larger than the maximum supported by the operating system.
The purple (left) band above the scale indicates the fraction of the total that is
available for data. The red (right) band indicates the fraction required for storing
the parity or mirrored information, depending on the fault-tolerance method used.
The red (right) band is only needed for RAID 1, RAID 4, or RAID 5.
This screen is first displayed showing the maximum-sized logical drive that can
be created for your drive array. You can reduce this amount if you want to create
more than one logical drive on the array. To reduce the size, type the number in or
drag the pointer to the left. Fine tune the size with the arrow buttons to the left of
the scale.
