HP 3PAR StoreServ Concepts Guide: HP 3PAR OS 3.1.3

SPOCC Service Processor Onsite Customer Care. A suite of service tools applications with a web-based
graphical user interface that is used to support the HP 3PAR storage system and its Service
Processor.
SPOCK Single Point of Connectivity Knowledge website. SPOCK is the primary portal used to obtain
detailed information about supported HP storage product configurations.
stale data Snapshot data that is no longer valid because the base volume does not have enough snapshot
administration or snapshot data space to record new changes to the base volume.
stale snapshot A snapshot that does not track the most recent changes to its base volume. The No Stale Snapshots
virtual copy policy halts writing data to the base volume in order to prevent loss of synchronization
between the volume and any snapshots.
started virtual
volume
A virtual volume that either passed auto-check upon system startup or was created since the system
was last restarted. Started virtual volumes are ready for read/write operations.
status bar The bar at the bottom of the HP 3PAR Management Console main window that contains messages
and icons. Status bar messages and icons can provide vital information about system status,
including the severity level of the most serious new alert in the alert pane.
step size The number of contiguous bytes that the system accesses before moving to the next chunklet.
stopped virtual
volume
A virtual volume that has not been started and is therefore not ready for read/write operations.
system backplane An electronic circuit board that contains sockets into which power supplies and controller nodes
are plugged.
system box Feature on the HP 3PAR Management Console main window toolbar that enables you to move
quickly between systems.
system manager Software component that negotiates between the system and the user interfaces such as the HP
3PAR Management Console and HP 3PAR OS CLI.
system view pane Area in the upper right corner of the HP 3PAR Management Console main window that displays
information about systems and system objects as you select the corresponding icons in the
navigation tree.
target mode The firmware setting for a port that is connected to a host.
target port The port that is connected to and receives commands from a host computer. Also known as a
host port.
TOC Table of Contents. The space on a physical disk that contains the internal description of the system.
The TOCs on all physical disks in the system contain the same information.
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.
TSIH Target Session Identifying Handle. An identifier, assigned by the iSCSI target, for a session with
a specific named initiator.
unspecified
property
When using the HP 3PAR Management Console, a property that has been included in a template
but does not have a defined value. When applying the template, the system will either use the
default value (when applicable) or calculate the optimized setting for you.
user data For standard base volumes, the data that is written to the user space.
user size The amount of user space in a virtual volume, or the size of the volume as presented to the host.
user space The space on a virtual volume that represents the size of the virtual volume as presented to the
host. For standard base volumes, the user space holds all user data. For Thinly-Provisioned Virtual
Volumes, no storage is actually allocated to user space, so the user space represents the volume's
virtual size.
virtual copy A snapshot created using the copy-on-write technique.
virtual copy policy Policy that determines the course of action to take when a volume's snapshot administration space
or snapshot data space becomes depleted.
virtual size The size that the volume presents to the host. For standard base volumes, the virtual size is equal
to the user space. For thinly-provisioned virtual volumes, no storage is actually allocated to user
space, so the virtual size is determined by whatever value is assigned to the user space.
