A collection of chunklets that reside on different physical disks and that are arranged as rows of RAID sets. When you create a CPG, the system creates and groups logical disks and assigns those logical disks to the CPG. Logical Unit Number. A number used to access a virtual volume that has been assigned to a particular host on a particular port. A rule that allows a particular host connected to a particular port to see a virtual volume as a specified LUN. A data redundancy technique used by some RAID levels (in particular RAID 5) to provide data protection on a storage array. Power Cooling Module.

A device inserted into a rack or virtual software that enables you to locally and remotely monitor and service systems. Thinly-Provisioned Virtual Volume. A virtual volume that maps to logical disk space associated with a Common Provisioning Group (CPG) and is therefore capable of growing on demand. For standard base volumes, the data that is written to the user space. A snapshot created using the copy-on-write technique. A virtual storage unit created by mapping data from one or more logical disks. Virtual logical unit number. A VLUN is a virtual volume-LUN pairing expressed as either an active VLUN or as a VLUN template. A rule that sets up the association between the name of the virtual volume and a LUN-host, LUN-port, or LUN-host-port combination. The three types of VLUN templates are host-sees, port-presents, and matched-set. Virtual Service Processor. World-Wide Name. A unique 64-bit value used to identify Fibre Channel devices on an arbitrated loop. The WWN consists of a prefix issued by the IEEE to uniquely identify the company and a suffix that is issued by the company. 63

LD
Logical disk. A collection of chunklets that reside on different physical disks and that are arranged
as rows of RAID sets. When you create a CPG, the system creates and groups logical disks and
assigns those logical disks to the CPG.
LUN
Logical Unit Number. A number used to access a virtual volume that has been assigned to a
particular host on a particular port.
matched-set VLUN
template
A rule that allows a particular host connected to a particular port to see a virtual volume as a
specified LUN.
parity
A data redundancy technique used by some RAID levels (in particular RAID 5) to provide data
protection on a storage array.
PCM
Power Cooling Module. A hardware component that includes the battery, fan, and power supply.
physical disk
A dual-ported Fibre Channel disk mounted onto a drive magazine.
port-presents
VLUN template
A VLUN template that allows any host connected to a particular port to see a virtual volume as
a specified LUN.
roles and rights
The roles and rights assigned to a user determine which tasks the user can perform with a system.
Service Processor
A device inserted into a rack or virtual software that enables you to locally and remotely monitor
and service systems.
TPVV
Thinly-Provisioned Virtual Volume. A virtual volume that maps to logical disk space associated
with a Common Provisioning Group (CPG) and is therefore capable of growing on demand.
user data
For standard base volumes, the data that is written to the user space.
virtual copy
A snapshot created using the copy-on-write technique.
virtual volume
A virtual storage unit created by mapping data from one or more logical disks.
VLUN
Virtual logical unit number. A VLUN is a virtual volume-LUN pairing expressed as either an active
VLUN or as a VLUN template.
VLUN template
A rule that sets up the association between the name of the virtual volume and a LUN-host,
LUN-port, or LUN-host-port combination. The three types of VLUN templates are host-sees,
port-presents, and matched-set.
VSP
Virtual Service Processor.
WWN
World-Wide Name. A unique 64-bit value used to identify Fibre Channel devices on an arbitrated
loop. The WWN consists of a prefix issued by the IEEE to uniquely identify the company and a
suffix that is issued by the company.
