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. See also VLUN template. primary system In a Remote Copy setup, the storage system on which the primary volume groups originate. primary volume group In Remote Copy, the set of volumes on the storage system to be copied. promote For physical copies: to break the association between a physical copy and a base volume by changing the physical copy into an independent base volume. For virtual copies: to copy the changes from a virtual copy back onto the base volume, therefore overwriting the base volume with the virtual copy. RAID 0 set Striped rows of chunklets on two or more physical disks. A RAID 0 set offers no data redundancy. RAID 10 (RAID 1) A group of mirrored chunklets. set RAID 50 (RAID 5) A group of parity-protected chunklets. Also known as a parity set. set RAID set A grouping of mirrored or parity-protected chunklets. RCFC Remote Copy over Fibre Channel. The use of HP 3PAR Remote Copy Software with two storage systems that are connected via Fibre Channel ports. See also HP 3PAR Remote Copy. RCIP Remote Copy over IP. The use of HP 3PAR Remote Copy Software with two storage systems that are connected via Ethernet ports. See also HP 3PAR Remote Copy. registered state A Fibre Channel switch function that allows notification to registered nodes if a change occurs change notification to other specified nodes. (RSCN) Remote Copy links The method by which information is sent and received between Remote Copy targets. Remote Copy pair The pair of storage systems on which Remote Copy operations are performed. Remote Copy target The description of a Remote Copy system on one system in the Remote Copy pair. Each system in a Remote Copy pair must have a target definition for the other system. Remote Copy volume group A group of virtual volumes that are logically related and for which there is a cross-volume ordering or writes. resynch, resynchronize To copy changes from one volume in a physical copy pair to the other because that volume was modified at some point after the physical copy operation took place. See also physical copy. row A grouping of RAID sets. Data is striped across the rows of RAID 10 and RAID 50 logical disks. row size The number of sets in a row. A row is a grouping of RAID sets. Data is striped across the rows of RAID 10 and RAID 50 logical disks. RSCN See registered state change notification. SCSI reservation/registration Allows multiple hosts to share a SCSI interface to access exported volumes. Multiple hosts can have registrations to a single volume, but only one host can have the reservation. secondary volume In Remote Copy, the set of copied volumes on the storage system. group set See set size. set size The number of chunklets in a set. Also known as mirror depth for RAID 1 sets and parity set for RAID 5 sets. SFP High-speed data transceiver, small in size and hot pluggable, allowing for an individual SFP connector to be replaced without replacing the entire module. small form-factor pluggable optical transceiver See SFP. snapshot A virtual or physical copy of a virtual volume. 422 Glossary
