NonStop System Glossary

Flex Processor Bay Configuration
A platform configuration that allows a choice of either sequential or even/odd numbering of
processors in an HP Integrity NonStop BladeSystem NB54000c. If you use the even/odd processor
numbering option or if you have more than eight sequential blades in your configuration, two
c7000 enclosures are required.
flexible disk configuration (FDC)
A configuration of an internal mirrored disk volume such that no single processor enclosure or I/O
enclosure can result in loss of online access to the volume.
foreground process
An Open System Services (OSS) process that belongs to a foreground process group.
foreground process group
In the Open System Services (OSS) environment, a process group whose members have privileges
for access to their controlling terminal that are denied to processes in background process groups
of that terminal. Each session with a controlling terminal has only one foreground process group
for that terminal. Contrast with background process group.
foreground process group ID
In the Open System Services (OSS) environment, the process group ID of a foreground process
group.
four-lane link
The four single-mode fiber-optic (SMF) ServerNet cables that connect the two NonStop Cluster
Switches on the same external fabric (for example, X1 and X2) in a split-star topology.
FOX
See Fiber Optic Extension (FOX).
FOX monitor process
The Fiber Optic Extension (FOX) monitor process for the ServerNet/FX adapter subsystem. The
process name is $ZZFOX.
FOX ring
The fiber-optic cabling that connects the nodes in a Fiber Optic Extension (FOX) cluster. This term
is also used to refer to the topology of a FOX network.
FOXMON
See FOX monitor process.
FPGA
See field-programmable gate array (FPGA).
F-PIC
See fiber-optic plug-in card (F-PIC).
FQDN
See fully qualified domain name.
