control cache control cache DIMM controller node controller node chassis copy data copy size copy-on-write snapshot CPG CPG template created host Customer Controlled Access daisy chaining data at rest Memory modules that support the microprocessors located in a controller node. A single control cache memory module. 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. An enclosure that houses all the controller nodes of a system. Data that occupies the snapshot data space (virtual copy space) on a virtual volume. The amount of snapshot data space (the logical disk space reserved for snapshots) in a virtual volume. 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. 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. 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. A host that is defined on the system but does not necessarily have any physically connected host paths or WWNs assigned to it. 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. Cabling configuration where components such as BBUs or drive cages are connected in succession. 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 data cache DIMM data cache riser card destination volume disk scrub drive bay drive cage drive chassis drive chassis cabinet drive chassis housing drive enclosure drive magazine drive magazine filler panel The dual in-line memory modules (DIMMs) that support the HP 3PAR ASIC located in a controller node. A single data cache memory module. A printed circuit board with DIMM sockets that hold data cache memory modules. The virtual volume to which data is copied during a virtual or physical copy operation. System functionality that scans physical disks for defects by reading and writing to the system's IDE disk. The space in a drive chassis into which a drive magazine is inserted. 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. An enclosure that houses drive cages. In a multicabinet system, any cabinet that is connected to a node cabinet but does not contain controller nodes. The enclosure that houses the components of a drive chassis. 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. 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. 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. 87
