Glossary

configuration data

Configuration data includes: identification data, port configuration data, operating parameters, SNMP configuration, and zoning configuration. A configuration backup file is required to restore configuration data if the CTP2 card in a non-redundant director is removed and replaced.

connectionless

Non-dedicated link. Typically used to describe a link between nodes which allows the switch to forward Class 2 or Class 3 frames as resources (ports) allow. Contrast this to the dedicated bandwidth that is required in a Class 1 Fibre Channel Service point-to-point link.

connector

See optical fiber connector.

control processor card

Circuit card that contains the director microprocessor. The CTP2 card also initializes hardware components of the system after power-on. A 10 Mbps RJ-45 twisted pair connector is located on the CTP2 card to connect to the Ethernet LAN and communicate with the HAFM server or a specific management station.

control unit

A hardware unit that controls the reading, writing, or displaying of data at one or more input/output units.

control unit port

An internal director port on the CTP2 card that communicates with the attached processor channels to report error conditions and link initialization.

CRC

See cyclic redundancy check.

CTP2

See control processor card.

CUP

See control unit port.

cyclic redundancy check

System of error checking performed at both the sending and receiving station using the value of a particular character generated by a cyclic algorithm. When the values generated at each station are identical, data integrity is confirmed.

DASD

Direct access storage device such as a disk drive.

datagram

See Class 3 Fibre Channel service.
