Offers

RAID 3/5

A redundant-
stripeset combining
the optimized data
transfers of RAID 3
with the striping of
parity of RAID 5.

RAIDset

3 - 14

Good throughput and read
bandwidth for a high request
rate of small to medium
transfers.

High Data Availability.

RAID 0

Stripeset

2 - 14

Good performance for both
read and write requests.
Provides load balancing with
each request requiring a
single data operation.

Data availability equivalent to
that of an individual disk
device.

RAID 1

Mirrorset

2 - 6 devices per
mirrorset, up to 20
mirrorsets per RAID
array

Good performance for read
requests.

High Data Availability

RAID 0 + 1

Striped
mirrorsets

2 - 20 mirrorsets

Performance for read requests
surpassing that of an
unstriped mirrorset since it
can achieve load balancing.

High Data Availability.

Individual Devices
(JBOD)

Disk Drive

Provides the storage capacity
and access speed of the disk
used.

If device fails, data is lost.

Once you select the type of storagesets that you want to use in your subsystem,
you must create them using an appropriate configuration manager.
