Globally unique
identifier (GUID)
It is a special type of identifier used in the software applications to provide a
unique reference number. The value is represented as a 32 hexadecimal character
string, such as the {21EC2020-3AEA-1069-A2DD-08002B30309D} and usually
stored as a 128 bit integer.
Hewlett-Packard
Authorization
Center (HPAC)
The 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 or the usable capacity of your P9000
disk array.
Inband data
collection
The inband mode of data collection is a method of collecting configuration data
for the XP and the P9000 disk arrays using a command device that is presented
to a host operating system.
IP version 6 (IPv6) The IPv6 is a new version of the Internet Protocol, which is a successor to the IP
version 4 (IPv4).
JRE Java Run time.
LDAP Lightweight Directory Access Protocol.
LDAP is used for centralized authentication, where the LDAP server authenticates
and authorizes P9000 Performance Advisor users.
LDEV Logical device. An LDEV is created when a RAID group is carved into pieces
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 also known as term volume.
LUN Logical unit number. A LUN results from mapping a SCSI logical unit number,
port ID, and LDEV ID to a RAID group. The size of the LUN is determined by the
emulation mode of the LDEV and the number of LDEVs associated with the LUN.
For example, a LUN associated with two OPEN-3 LDEVs has a size of 4,693
MB.
MIX A circuit board in the disk control unit that includes disk adapters and channel
adapters for interfacing disk drives and the host to cache memory.
MP blades The MP blades are the microprocessor blades in the P9000 disk arrays. Each
MP blade has four MPs residing on it.
The MPs/DKPs that reside on the CHAs and the DKAs in the XP disk arrays form
part of the MP blades in the P9000 disk arrays.
Multiprocessor
(MP)
In an XP disk array, the MPs are installed on the CHAs and the DKAs. The MPs
on a CHA are addressed as CHPs and the MPs on a DKA are addressed as
DKPs.
In a P9000 disk array, the MPs do not reside on the CHAs and DKAs. Instead,
they form part of the MP blades.
Outband The outband mode uses the TCP/IP to directly connect to the XP or the P9000
disk array and collect the configuration data through the array SVP. Using the
outband mode ensures that the performance of the SAN is not affected because
of the data collection.
P9000
Performance
Advisor
The HP StorageWorks P9000 Performance Advisor is a software product from
HP for monitoring the XP and the P9000 storage subsystems.
