connectionless
Nondedicated link. Typically used to describe a link between nodes which allows the
switch to forward Class 2 or Class 3 frames as 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 CTP card also initializes
hardware components of the system after power-on. A 10 Mbps RJ-45 twisted pair
connector is located on the CTP card to connect to the Ethernet LAN and communicate
with the HP EFC Server or a specific management station.
CRC
See cyclic redundancy check.
CTP
See control processor card.
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.
D
DASD
Direct access storage device such as a disk drive.
datagram
See Class 3 Fibre Channel service.
