Managing BlackArmor Volumes, Shares, and Storage

This table explains the different levels of RAID supported by your BlackArmor server.

Table 1: Supported RAID Levels for Volumes

	Number of
RAID Level of Volume	Disk Drives	Description
	Required

RAID 0	2 – 4	A volume where data is distributed evenly
(Also known as striping)		(striped) across the disk drives in equal-sized
		sections. A striped volume does not maintain
		redundant data, and so offers no data protection.

RAID 1	2	A volume where one disk drive is a mirror of the
(Also known as mirroring)		other (the same data is stored on each disk
		drive). Provides data protection.

RAID 5	3 – 4	A volume with RAID 5 uses data striping and par-
		ity data to provide redundancy. (Parity is extra
		information that’s used to re-create data if a disk
		drive fails. In volumes with RAID 5, parity data is
		striped evenly across the disk drives with the
		stored data.)

RAID 10	4	A volume with RAID 10 is built from two or more
		equal-sized RAID 0 volumes. Data in a volume
		with RAID 10 is both striped and mirrored.

Span	1 – 4	A group of disk drives in a server, not protected
(Also known as a JBODa)		by RAID.

a.‘Just a Bunch of Disks’.

Seagate recommends that only users familiar and comfortable with RAID technology make changes to the server’s RAID protection.

Creating New Volumes

As a BlackArmor administrator, you can create all the shares you want in the default volume, or you can create more volumes using BlackArmor Manager. When you create a volume, you can specify:

•The size of the volume

•The disk drive(s) you want to use

•The level of RAID protection it should have (see page 31)

You can use the same disk drives in multiple volumes providing there is available space on those drives. For instance, you could use half the space on disk drives 1, 2, and 3 to create Volume A, and the other half of the space on the same disk drives to create Volume B.

To create a new volume, open BlackArmor Manager (see page 17). Volumes are in the Storage menu. For more information on volumes, including deleting and modifying volumes, see the online Help.
