Working with Volumes

By default, the available storage space in your BlackArmor server is configured into one
volume that's protected by RAID 1.

Understanding RAID

RAID stands for Redundant Array of Independent Disks and is a technology that builds
redundancy into your storage system to help keep your data safe from disk drive failures and
other catastrophes.
RAID comes in many levels, which vary according to the amount of protection they provide
(and how they provide it), and the number of disk drives they support.
By default, your BlackArmor server is preconfigured with RAID 1 protection, which "mirrors"
the server's data, keeping exact copies on both drives.
This table explains the different levels of RAID supported by your BlackArmor server.
Table 1: Supported RAID Levels for Volumes
RAID Level of Volume
RAID 0
(Also known as striping)
RAID 1
(Also known as mirroring)
Span (Also known as a
JBOD, Just a Bunch of
Disks)
BlackArmor® NAS 220 User Guide (Version 2)
Number of
Disk Drives Description
Required
2 – 4 A volume where data is distributed evenly
(striped) across the disk drives in equal-sized
sections. A striped volume does not maintain
redundant data, and so offers no data protection.
2 A volume where one disk drive is a mirror of the
other (the same data is stored on each disk
drive). Provides data protection.
1 – 4 A group of disk drives in a server, not protected
by RAID.
