Working with a Stripe Set of RAID-5 Sets (RAID-50)
A stripe set of RAID-5 sets (also known as RAID-50) is a multi-level
container made up of a top-level stripe set and two or more
underlying RAID-5 sets of equal size. A stripe set of RAID-5 set’s
data is redundant. See the Flexible Array Storage Tool User’s Guide for
a complete description of a stripe set of RAID-5 sets and other
container concepts.
To work with a stripe set of RAID-5 sets, you must understand:
■ The stripe set of RAID-5 set attributes you can specify
■ How to create a stripe set of RAID-5 sets
■ Stripe set of RAID-5 set creation in a NetWare environment
■ Stripe set of RAID-5 set creation in a UNIX environment
■ Some tasks to perform after creating a stripe set of RAID-5 sets
The following sections discuss each of these topics.
Understanding the Stripe Set of RAID-5 Sets Attributes You can
Specify
You use the container create mstripe command to create a
stripe set of RAID-5 sets. Before creating a stripe set of RAID-5 sets,
consider the following attributes you can specify:
■ stripe size
■ container label
Specifying Stripe Size When Creating a Stripe Set of RAID-5 Sets
The stripe size attribute indicates the stripe size for a container.
Stripe size is the amount of data written to a partition before the I/O
data stream switches to the next partition in the stripe. The stripe
size can be 8 KB, 16 KB, 32 KB, or 64 KB. You need to determine the
stripe size that is most suitable for your environment. Note that you
can use the
container reconfigure command at a later time to
change the stripe size. See the container reconfigure
command in chapter Chapter 9, Modifying Containers, for a
description of the
container reconfigure command. You
