GLOSSARY
8B/10B -----------------------------A data-encoding scheme developed by IBM for translating byte-wide
data to an encoded 10-bit format.
ANSI --------------------------------American National Standards Institute.
bandwidth -------------------------The amount of data that can be transmitted over a channel.
bps ----------------------------------bits per second.
broadcast --------------------------Sending a transmission to all nodes on a network.
channel -----------------------------A point-to-point link that transports data from one point to another at the
highest speed with the least delay, performing simple error correction in
hardware. Channels are hardware intensive and have lower overhead
than networks. Channels do not have the burden of station management.
Convection Cooled--------------- Heat dissipated by the flow of fluids. In the case of circuit boards, the
typical heat dissipation by airflow.
Conduction Cooled -------------- Heat dissipated by transfer between solids. In the case of circuit boards,
heat transfer from a thermal conductive layer in the board to a physically
connected mass such as a large aluminum plate.
CMC --------------------------------Common Mezzanine Card.
CRC --------------------------------Cyclic Redundancy Check. A code used to check for errors in Fibre
Channel.
DMA --------------------------------Direct Memory Access.
DMA write ------------------------The DMA engine on the bus controller writes the data from the host
computer to the SRAM buffer, freeing the host CPU for other tasks.
(FibreXpress board becomes a master for the bus.)
FC -----------------------------------Fibre Channel.
FC-PH ------------------------------Fibre Channel Physical interface. Fibre Channel Physical standard,
consisting of the three lower levels, FC-0, FC-1, and FC-2.
Fibre Channel --------------------Fibre Channel (FC) is a serial data transfer interface technology
operating at speeds up to 1 Gbps. It is defined as an open standard by
ANSI. It operates over copper and fiber optic cabling at distances of up
to 10 kilometers. Supported topologies include point-to-point, arbitrated-
loop, and fabric switches.
FibreXpress -----------------------A Curtiss-Wright Controls, Inc. trademark name for a family of
networking products that maximize the superior communication and
interconnect capabilities of ANSI standard Fibre Channel. The FX200
series of 64-bit adapters support up to 200 MB per second (400 MB per
second duplex) throughput. The FX100 series supports 100 MB per
second throughput.
FibreXtreme ----------------------A Curtiss-Wright Controls, Inc. trademark name for a family of
networking products based on the original Simplex Link technology,
Curtiss-Wright Controls’ FibreXtreme Serial FPDP Data Link moves
data at a sustained 247 MB per second with microsecond latency.
Supports up to 2.5 Gbps serial data link using a highly specialized
communications protocol optimized for maximum data throughput.
FIFO --------------------------------first in first out
