HP StorageWorks P9000 Performance Advisor Software v5.2 Install Guide (T1789-96317, May 2011)

Command View
(CV)
Replaced by the Command View Advanced Edition Suite Software.
Command View
AE (CV AE)
The Command View Advanced Edition Suite Software replaces the XP Command
View Software to manage the XP and P9000 disk arrays.
Continuous Access
Synchronous (Cnt
Ac-S)
The Continuous Access Synchronous Software provides remote replication
between the disk arrays that belong to the P9000 and the XP families.
Continuous Access
Journal (Cnt Ac-J)
The Continuous Access Journal Software is an asynchronous mirroring program
similar to the Continuous Access Asynchronous, except that the transactions to
be written to the secondary disk array are maintained in a disk-based journal
file. This provides better performance for the secondary disk array systems that
are not highly available or that may be subject to bandwidth contention from
other applications.
CSV Comma-separated value.
DASD Fast Write
(DFW)
The DFW is the function of a storage controller that allows caching of active
write data without exposure of data loss. This is achieved by journaling of the
active write data in the NVS.
Disk Adapter
(DKA)
The DKA is a PCB in the XP and the P9000 disk arrays. It manages the data
transfer between the cache and the physical drives in the backend.
In an XP disk array, the DKA is one of the two PCB types that contains the MPs.
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.
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.
Domain Name
System (DNS)
The DNS corresponds to the [servername].[domain name] of your system.
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.
