Making The Array Available For Use - Adaptec DuraStor 7220SS User Manual

Adaptec Storage Manager Pro for DuraStor User's Guide
Storage Manager Pro uses the default stripe size (64k)
recommended by the DuraStor external RAID controller. This is
generally the best stripe size to use. The other stripe size options
are 16k and 64k.
Note: For a RAID 5 set, use a stripe size of 64k for optimum
performance.
The following list shows some guidelines to use to decide if you
want to change the stripe size.
If you want better
Random I/O performance
Large sequential I/O performance
Note: Stripe size in a stripe set of RAID 5 sets (RAID 0/5)
cannot exceed one megabyte. If you select a RAID 0/5
configuration which exceeds the one megabyte limit,
Storage Manager Pro prompts you to revise the stripe size
or reduce the number of RAID 5 sets.
You can set the default stripe size to use in array creation in the
Default Array Creation Properties dialog box. See Viewing and
Setting the Default Array Creation Properties on page 2-10.

Making the Array Available for Use

After you create an array, you typically make the array available to
users. In some cases, you may need to reboot the system before the
array can be accessible. Refer to your operating system's
documentation for more information.
To make the array available for use in Widnows, you must partition
it, assign it a drive letter, and format it. Refer to the documentation
for Windows NT Disk Administrator or Windows 2000 Disk
Manager for more information. You may need to rescan the
controller before the array becomes available.
