Strip Size/Full Stripe Size Strip size is the amount of data that is stored on
each physical drive in the array. The full stripe
size is the amount of data that the controller can
read or write simultaneously on all the drives in
the array. For RAID levels that support fault
tolerance through parity, the parity information is
calculated one full strip size at a time.
You can specify from 8KiB to 1024KiB, depending
on the number of disks and RAID level. The
default value is all available space.
If you use Smart Array S100i SW RAID, the
minimum size is 16KiB, and the maximum size is
256KiB.
Size Values in decimal; minimum RAID size is 16 MiB.
Unit Size Logical drive unit size (MiB/GiB/TiB).
Acceleration Method Logical drive acceleration method (controller
cache or none).
