Glossary

This section describes common hardware, software, SCSI, and Fibre Channel terms

that are used in the QMS documentation.

Adapter An adapter is the board that interfaces between the host

system and disk. Adapter is synonymous with host adapter,

adapter board, and Host Bus Adapter (HBA). In the QMS

documentation, the term QLA2xxx adapter is used.

AL_PA AL_PA stands for Arbitrated Loop_Physical Address. This

is a low level address on the Fibre Channel loop.

Arbitrated loop An arbitrated loop is a non-point to point circular topology

where two or more ports can be interconnected, but only two

ports can communicate at one time. All communication is

passed through all ports connected onto the loop.

Cluster A cluster is multiple servers linked together sharing all

resources to deliver high-availability/high-performance

computing.

CRC CRC stands for Cyclic Redundancy Check. CRC is the error

detection technique used by most communication protocols

including Ethernet, Ultra DMA (UDMA), Fibre Distributed

Data Interface (FDDI), and Fibre Channel. CRC is more

powerful than simple parity checking.

DCE DCE stands for Distributed Computing Environment, a

remote procedure call developed by the Open Software

Foundation (OSF).

DMI DMI stands for Desktop Management Interface. DMI is the

industry standard for asset tracking and system management

from the Desktop Management Task Force (DMTF). At the

time of publication, the DMI revision level is 2.0.
