control cache
Memory modules that support the microprocessors located in a controller node.
control cache
DIMM
A single control cache memory module.
controller node
An individual device that works with other controller nodes to cache and manage data in a system
and to provide hosts with a coherent, virtualized view of the storage system.
controller node
chassis
An enclosure that houses all the controller nodes of a system.
copy data
Data that occupies the snapshot data space (virtual copy space) on a virtual volume.
copy size
The amount of snapshot data space (the logical disk space reserved for snapshots) in a virtual
volume.
copy-on-write
snapshot
A snapshot of a virtual volume made with the copy-on-write technique. This type of snapshot
consists of a pointer to the source volume and a record of every change made to the source
volume since the snapshot was created.
CPG
Common Provisioning Group (also known as a storage pool or logical disk pool). A set of logical
disks from which you can create virtual volumes and virtual copies that are capable of allocating
storage on demand.
CPG template
Common Provisioning Group template. A CPG template contains a set of common provisioning
group and logical disk parameters that HP 3PAR Management Console users can apply in order
to create a new Common Provisioning Group.
created host
A host that is defined on the system but does not necessarily have any physically connected host
paths or WWNs assigned to it.
Customer
Controlled Access
A software tool that restricts connections between the service processor and the HP 3PAR technical
support center. Customer Controlled Access is independent of the user's network firewall and
works whether the connections are made through the Internet or through a point-to-point modem
connection.
daisy chaining
Cabling configuration where components such as BBUs or drive cages are connected in succession.
data at rest
Archived data. Data at rest may also include data that is seldom accessed and that is stored on
hard drives, backup disks, or on a storage area network.
data cache
The dual in-line memory modules (DIMMs) that support the HP 3PAR ASIC located in a controller
node.
data cache DIMM
A single data cache memory module.
data cache riser
card
A printed circuit board with DIMM sockets that hold data cache memory modules.
destination volume
The virtual volume to which data is copied during a virtual or physical copy operation.
disk scrub
System functionality that scans physical disks for defects by reading and writing to the system's
IDE disk.
drive bay
The space in a drive chassis into which a drive magazine is inserted.
drive cage
A component in a rack or chassis that contains a drive. Drive cages connect to nodes for
communication with hosts. Drives may be Fibre Channel or iSCSI.
drive chassis
An enclosure that houses drive cages.
drive chassis
cabinet
In a multicabinet system, any cabinet that is connected to a node cabinet but does not contain
controller nodes.
drive chassis
housing
The enclosure that houses the components of a drive chassis.
drive enclosure
A component used for housing drive cages in the front of the enclosure and nodes and I/O
modules in the rear of the enclosure.
drive magazine
An electronic circuit board mounted on a mechanical structure that is inserted into a drive bay
in a drive cage. A drive magazine holds up to four physical disks.
drive magazine
filler panel
The panel used to seal off an empty drive bay. All drive bays in a drive cage must be sealed for
EMI and airflow considerations.
