configuration. See also view mode.
monitoring target An object selected to be monitored using Performance Monitor.
MP microprocessor
MP blade Processor blade.
MP blade ESW Access paths between the MP bland and the cache switch.
multipathing A performance and fault-tolerant technique that uses more than one physical connection between
the storage system and host system. Also called multipath I/O.
NAS network-attached storage

NVS nonvolatile storage
OPEN- x
A logical unit (LU) of fixed size (for example, OPEN-3 or OPEN-9) that is used primarily for
sharing data between mainframe and open-systems hosts using Data Exchange.
OS operating system
P-VOL Primary volume.
pair Two logical volumes in a replication relationship in which one volume contains original data to
be copied and the other volume contains the copy of the original data. The copy operations can
be synchronous or asynchronous, and the pair volumes can be located in the same storage
system (in-system replication) or in different storage systems (remote replication).
parity group See RAID group.
PB petabyte
PDEV physical device
pool A set of volumes that are reserved for storing pool volumes (pool-VOL), and used by Fast Snap,
Thin Provisioning, Thin Provisioning MF, Smart Tiers, Smart Tiers MF, Real Time Smart Tier,
Real Time Smart Tier for Mainframe write data.
pool volume A logical volume that is reserved for storing snapshot data for Fast Snap operations or write
(pool-VOL) data for Thin Provisioning, Thin Provisioning MF, Smart Tiers, Smart Tiers MF, Real Time Smart
Tier, Real Time Smart Tier for Mainframe.

prestaging of Places specific data in Cache Residency cache before it is accessed by the host. When
data prestaging is selected, the host locates the prestaged data in the CR cache from the first access,
thus enhancing its access performance.
primary site The physical location of the storage system that contains the original data to be replicated and
that is connected to one or more storage systems at the remote or secondary site via remote
copy connections. A primary site can also be called a "main site" or "local site".
The term "primary site" is also used for host failover operations. In that case, the primary site
is the host computer where the production applications are running, and the secondary site is
