The RADIUS VSA is required for authorizing the P9000 Performance Advisor
users for the RADIUS authentication. It must have a vendor ID of 11 that is
assigned to Hewlett-Packard by IANA and an attribute type of 1. Your system
administrator must add a RADIUS VSA to the user profile on the RADIUS server.
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 P9000 and XP disk
arrays.
Read/Write (R/W) Read-write access.
RAID group A group of disks configured to provide enhanced redundancy, performance, or
both. Specifically, four or eight physical hard disk drives (HDDs) installed in a
disk array and assigned a common RAID level.

Authentication Dial
The RADIUS authentication is a networking protocol that provides centralized
authentication, where the RADIUS server authenticates and authorizes the P9000
Performance Advisor users.In User Service

Remote Web
Console (RWC)
An HP StorageWorks product. A browser-based program installed on the SVP
that allows you to configure and manage the disk array.
SAN Storage area network. A network of storage devices available to one or more
servers.
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.
sidefile An area of cache used to store the data sequence number, record location,
record length, and queued control information.
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
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).
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.
