HP StorageWorks P9000 Performance Advisor Software v5.3 User and Troubleshooting Guide (T1789-96322, August 2011)

Disk Controller
(DKC)
The array enclosure that contains the channel adapters and service processor
(SVP).
Disk Processor
(DKP)
In the XP disk arrays, the MP that resides on a DKA is addressed as the DKP.
DKPs does not exist in the P9000 disk arrays. All the MPs/DKPs form part of the
MP blades in the P9000 disk arrays.
DKU Disk cabinet unit. The array cabinet that houses the physical disks.
Device Special File
(DSF)
In the non windows systems, the DSF is an interface for a device driver that
appears in a file system as if it were an ordinary file. In the Windows systems,
the DSF allows the software to interact with a device driver using the standard
input or the output system calls.
emulation mode The LDEVs associated with each RAID group are assigned an emulation mode
that makes them operate like OPEN system disk drives. The emulation mode
determines the size of an LDEV.
OPEN-3: 2.46 GB
OPEN-8: 7.38 GB
OPEN-9: 7.42 GB
OPEN-E: 13.56 GB
OPEN-K: Not available
OPEN-L: 36 GB
OPEN-M Not available
OPEN-V: User-defined custom size
External Storage An external storage that is connected to an XP or a P9000 disk array.
FC Fibre Channel. A network technology primarily used for storage networks.
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.
HDD Hard Disk Drive
Host Group A group of hosts that belong to a particular WWN group.
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).
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.
