HP XP P9000 Performance Advisor Software v5.5 Install Guide (T1789-96339, February 2013)

RAID Manager RAID Manager is installed on the host systems and is used to manage activity with certain program
products of the XP subsystem (for example, pairing activity). Commands can be performed
manually or through the scripting for large jobs.
RAID Manager
Library (RML,
RMLIB)
The RAID Manager Library is an API library that enables third-party software products to directly
operate some of the functions on the HP XP P9000 and XP disk arrays.
Read/Write (R/W) Read-write access.
Remote
Authentication Dial
In User Service
(RADIUS)
The RADIUS authentication is a networking protocol that provides centralized authentication,
where the RADIUS server authenticates and authorizes the HP XP P9000 Performance Advisor
users.
Remote Web
Console (RWC)
An HP Storage software product. A browser-based program installed on the SVP that allows you
to configure and manage the disk array.
S
SAN Storage area network. A network of storage devices available to one or more servers.
Shared Memory
(SM)
The shared memory in an XP disk array stores shared information about the XP subsystem and
the cache control information.
The shared memory in a P9000 disk array stores shared information about the HP XP P9000
subsystem and the cache control information.
This type of information is used for the exclusive control of the subsystem. Similar to the cache,
the shared memory is controlled as two areas of memory and is fully non-volatile (sustained for
approximately seven days).
sidefile An area of cache used to store the data sequence number, record location, record length, and
queued control information.
Smart Tiers The Smart Tiers are applicable only for the P9000 disk arrays and configured using the ThP
V-Vols. They ensure that the highly utilized ThP pages are relocated to the fastest drive in the ThP
pool. A maximum of three tiers can be configured.
Snapshot The snapshot is a business copy volume type that depicts a point-in-time copy of the original
primary volume.
SSL Secure Socket Layer.
Storage Logical
Partition (SLPR)
NOTE: The SLPR component is applicable only for the XP disk arrays. It does not exist in the
P9000 disk arrays. As a result, the SLPR-related data is not displayed in HP XP P9000 Performance
Advisor for the P9000 disk arrays.
The SLPR is a partition of the RAID500 to which the host ports (1 or more) and the CLPRs (1 or
more) are assigned. The SLPR0 will always exist (cannot be deleted). Sometimes, the SLPR acronym
includes an additional word. For example, Storage administrator Logical Partition or Storage
management Logical Partition, both mean the same. The purpose of the SLPR is to allow multiple
administrators to manage a subsystem without the risk of causing mistakes that can destroy another
user's volumes, or reduce other user's expected performance by using more components (e.g.
cache) than required.
Storage Subsystem
Identification (SSID)
The SSID (also called Subsystem Identifier) is a user assigned number that identifies a DASD
subsystem. This number is set by the service representative at the time of the installation and it is
included in the product data. The Valid SSID values are 0004-FFFC.
SVP Service processor. A notebook computer built into the disk array. The SVP provides a direct
interface to the disk array and used only by the HP service representative.
T
Thin Provisioning
(ThP, TP)
Using the thin provisioning, you can operate with a global pool of LDEVs that are not assigned
to a physical storage. The XP and the P9000 disk arrays add virtual capacity from the pool of
129
