Glossary
FRU
(field-replaceable
unit)
A hardware assembly that can be replaced on site, instead of at the
point of manufacture, by trained personnel.
G
GBIC
(Gigabit Interface
Converter)
A device for converting Fibre Channel signals from electrical to
optical, and vice versa.
H
HBA (host-bus
adapter)
Another name for Fibre Channel adapter.
host
hot repair
hub
An FC-AL switching device that allows multiple servers and targets
such as storage systems to connect at a central point. A single hub
configuration appears as a single loop.
L
LCC (link control
card)
A FRU in DAE2 enclosures, integrated into the SP module in a
CX200-Series DPE2. An LCC connects Fibre Channel signalling to the
disk modules, and provides Fibre Channel connectivity between the
SP, disks, and other enclosures. It also provides bypass capability for
faulted or missing units, and monitors and controls enclosure
elements.
LUN (logical unit)
One or more disk modules (each having a head assembly and
spindle) bound into a group — usually a RAID group. The operating
system sees the LUN, which includes one or more disk modules, as
one contiguous span of disk space.
M
memory module
N
node
Any device with a Fibre Channel interface (such as an HBA in a
server or a storage system’s SP) that connects to a Fibre Channel loop.
