HP StorageWorks XP Performance Advisor Software v4.6 Install Guide (T1789-96096, July 2010)

• OPEN-V: User-defined custom size
Inband data
collection
A method of collecting configuration data for an XP Disk Array using a command
device that is presented to a host operating system.
JRE Java Run time.
HPAC Hewlett-Packard Authorization Center
Hewlett-Packard Authorization Center license key website (http://
webkey.external.hp.com/), where you generate a license for a specified internal
raw disk capacity of your XP Disk Array.
LDAP Lightweight Directory Access Protocol.
The LDAP is used for centralized authentication, where the LDAP server
authenticates and authorizes XP Performance Advisor users.
LDEV Logical Device.
An LDEV is created when a RAID group is divided into smaller partitions or
volumes according to the selected host emulation mode (that is, OPEN-3, OPEN-8,
OPEN-9). The number of resulting LDEVs depends on the selected emulation
mode. The term LDEV is often used synonymously with the term Volume.
LUN Logical Unit Number.
A LUN is created by mapping a SCSI logical unit number, port ID, and an LDEV
ID to a RAID group. It is always associated with a single LDEV and presented to
a host. The optional LUSE feature allows a LUN to be associated with 1 to 36
LDEVs. Thereby, enabling for applications to access a single large pool of storage.
Outband The Outband mode uses Remote Method Invocation (RMI) to collect data from
an XP Disk Array through its SVP, where XP Performance Advisor directly
communicates with the XP Disk Array to collect its configuration data.
Outband is the preferred mode of configuration data collection for an XP Disk
Array of type XP10000, XP12000, XP20000, or XP24000. If the SVP on the
XP Disk Array is accessible, HP recommends that you use the Outband mode of
configuration data collection, as XP Performance Advisor receives the accurate
internal raw disk capacity from the XP Disk Array (same as shown by RWC)
through the Outband mode.
Using the OutBand mode ensures that the performance of Storage Area Network
(SAN) is not affected because of data collection.
RADIUS Remote Authentication Dial In User Service.
The RADIUS Authentication is a networking protocol that provides centralized
authentication, where the RADIUS server authenticates and authorizes XP
Performance Advisor users.
RADIUS VSA RADIUS Vendor Specific Attribute.
The VSA is required for authorizing XP Performance Advisor users for 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
Vendor-Specific Attribute (VSA) to the user profile on the RADIUS server.
R/W Read/Write (r/w) operations.
RAID Group A RAID group is a group of 4 or 8 physical hard disk drives (HDDs) installed in
an XP Disk Array and assigned a common RAID level.
