RAID-0 Volume Requirements

When you are working with RAID-0 volumes, consider the following:

• Use components that are each on different controllers to increase the number of simultaneous reads and writes that can be performed.

• Do not create a stripe from an existing file system or data. Doing so will destroy data. Instead, use a concatenation. (You can create a stripe from existing data, but you must dump and restore the data to the volume.)

• Use disk components of the same size for stripes. Striping components of different sizes results in wasted disk space.

• Set up a stripe's interlace value to better match the I/O requests made by the system or applications.

• Because a stripe or concatenation does not contain replicated data, when such a volume has a component failure, you must replace the component, recreate the stripe or concatenation, and restore data from a backup.

• When you recreate a stripe or concatenation, use a replacement component that has at least the same size as the failed component.
