RAID set A grouping of mirrored or parity-protected chunklets.
RAID type RAID 0, RAID 10 (1), RAID 50 (5), and RAID MP (6) are all supported RAID types; however, not
all RAID types may be available on your system.
RCFC Remote Copy over Fibre Channel. The use of Remote Copy with two systems that are connected
via Fibre Channel ports.
RCIP Remote Copy over IP. The use of Remote Copy with two systems that are connected via Ethernet
ports.
region A subdivision of a logical disk or virtual volume. The size of a region is always a multiple of 32
MB.
resynchronize To copy changes from one volume in a physical copy pair to the other volume because the original
volume was modified at some point after the physical copy operation took place.
roles and rights The roles and rights assigned to a user determine which tasks the user can perform with a system.
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 Registered State Change Notification. A Fibre Channel switch function that allows notification to
registered nodes if a change occurs to other specified nodes.
safety breaker The device used to power on and power off the power distribution unit. The safety breaker also
prevents power surges in the AC line from damaging a system.
second virtual
volume backup
node
The controller node that takes over for the virtual volume backup node if the virtual volume node
fails.
secondary path Connection between a controller node initiator port and a physical disk that is used when the
primary path is inaccessible (a failure condition). The primary and secondary paths are not
user-configurable; they are determined by drive magazine placement.
self-encrypting
drive
A self-encrypting drive (SED) uses Advanced Encryption Standard keys to protect data from
unauthorized access. SEDs contain special firmware and an application-specific integrated circuit
(ASIC) that provides encryption. When encryption is enabled, the SED will lock when power is
removed, and it will not be unlocked until the matching key from the HP 3PAR StoreServ system
is used to unlock it.
Service Processor A device inserted into a rack or virtual software that enables you to locally and remotely monitor
and service systems.
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.
severity indicator Icon in the HP 3PAR Management Console alert pane or on the HP 3PAR Management Console
status bar that shows the seriousness of an alert.
SFP Small form-factor pluggable transceiver.
snapshot A virtual or physical copy of a virtual volume.
snapshot
administration
space
The space on a virtual volume that is used to track changes to the data from the time that a
snapshot of a virtual volume was created.
source volume The virtual volume from which a copy is made.
spare chunklet A chunklet that is reserved for use in case of a failure in the system. A certain number of chunklets
are reserved for use as spares during the system setup and installation process; however, the
system may temporarily set aside additional spares even though these chunklets are not
permanently designated for use as spares.
spare status Indicates whether a chunklet is reserved as a spare or has been selected by the system for use
in sparing on a temporary basis.
sparing The automatic relocation of chunklets on a physical disk when a logging logical disk becomes
full.
