Configuring Storage Settings

Managing Storage Settings

Through the Web interface, you can create, edit, deconstruct, and view RAID (redundant array of
independent disks) and other storage objects.

Available RAID Levels in the NA-1400

The NA-1400 supports three types of RAID configurations for the data partition. You can use
these RAID levels on a multi-drive appliance, whether or not you install a hardware RAID card. If
there is no hardware RAID card installed, you can use software RAID. RAID levels 0, 1, and 5
are available.

RAID 0: Single Large Volume

This type of RAID also is known as striping. RAID 0 interleaves blocks of data between several
drives. Even though multiple drives exist in the array, to the user a RAID 0 appears as a single
large volume. It is important to understand however, that there is no form of data backup when
using a RAID 0. If a single drive fails, you will lose the entire array. This type of RAID should
not be used for mission-critical data. RAIS 0 is available for any system with two or more drives.

Linear (JBOD): Single Large Volume, No Striping

This type of RAID is similar to RAID 0. However, it does not use striping. Instead, user data is
written sequentially. JBOD works more slowly than RAID 0. RAID Linear can be built on two or
more drives.

RAID 1: Mirroring

This type of RAID is used to create a mirror copy of the information that is contained on one or
more of the disks. In this method, a mirror is created for each drive that contains data. For
example, in a two-drive RAID 1 setup, both drives contain exactly the same data. Since there is
100% redundancy, there is no risk of data loss if one drive fails. RAID 1 is available for any
system with two or more drives.

RAID 5: Disk Striping with Distributed Parity

This type of RAID features both striping and redundancy. RAID 5 uses a technique called
distributed parity, which enables you to recover data if one drive in the RAID fails. In addition,
data blocks are interleaved evenly across the drives in parity bits. RAID 5 is available only for
systems that have three or more drives.
