Enables striped arrays this sets the amount of data written to one disk before
moving on to the next disk in the array.

The stripe size is defined as the size, in kilobytes (1024 bytes), of a single
I/O operation. A stripe of data (data residing in actual physical disk
sectors, which are logically ordered first to last) is divided over all disks
in the Drive Group. The software default stripe size is 8 KB. The
recommended stripe size is 64KB.
Once set, the stripe size cannot be changed without first copying all of the
data off of the array, changing the stripe size, re-initializing the drives,
and copying the saved data back onto the array. In a large capacity array,
this operation could take several hours and inconvenience many people.
Make any changes before the array is placed into service.
The stripe size function is used to tune the controller performance for a
specific environment or application. Generally, stripe size optimization is
as follows:
•
smaller stripe sizes provide better performance for random I/O
(e.g., RAID 5, network file service, or OLTP processing)
•
larger stripe sizes provide better performance for sequential transfers
(e.g., RAID 0, RAID 1, digital video, etc.,)
Changing the stripe size alters the way data is written on the disk drives.
e
Ensure that the option for "Installation Abort" is set to Disabled. This
will prevent the controller from saving a configuration file when a
possible problem exists with the file.
