TB Terabyte. A term defining either:

• A data transfer rate.

• A measure of either storage or memory capacity of 1,099,5111,627,776 (2

) bytes.

See also dirty data.

UPS Uninterruptible Power Supply. A battery-operated power supply guaranteed to provide power to

an electrical device in the event of an unexpected interruption to the primary power supply.

Uninterruptible power supplies are usually rated by the amount of voltage supplied and the length

of time the voltage is supplied.

UUID Unique Universal Identifier. A unique 128-bit identifier for each component of an array. UUIDs

are internal system values that users cannot modify.

virtual disk Variable disk capacity that is defined and managed by the array controller and presented to

hosts as a disk. Can be called Vdisk in the user interface.

virtual disk copy A clone or exact replica of another virtual disk at a particular point in time. Only an active virtual

disk can be copied. A copy immediately becomes the active disk of its own virtual disk family.

See also active member of a virtual disk family.

virtual disk family A virtual disk and its snapshot, if a snapshot exists, constitute a family. The original virtual disk

is called the active disk. When you first create a virtual disk family, the only member is the active

disk.

See also active member of a virtual disk family, virtual disk copy.

Vraid The level to which user data is protected. Redundancy is directly proportional to cost in terms of

storage usage; the greater the level of data protection, the more storage space is required.

Vraid0 Optimized for I/O speed and efficient use of physical disk space, but provides no data

redundancy.

Vraid1 Optimized for data redundancy and I/O speed, but uses the most physical disk space.

Vraid5 Provides a balance of data redundancy, I/O speed, and efficient use of physical disk space.
