Expand-over-ServerNet line-handler process
Expand-over-ServerNet line-handler process. An Expand line-handler process that uses
the NETNAM protocol to access the network access method (NAM) interface provided
by the ServerNet monitor process, $ZZSCL. The Expand-over-ServerNet process
handles incoming and outgoing Expand messages and packets going outside a
ServerNet cluster and handles security-related messages within the cluster.
Expand-over-SNA line-handler process. An Expand line-handler process that uses the
NETNAM protocol to access the network access method (NAM) interface provided by
a SNAX/APN line-handler process.
Expand-over-X.25 line-handler process. An Expand line-handler process that uses the
NETNAM protocol to access the network access method (NAM) interface provided by
an X25AM line-handler process.
Expand packet. See Expand frame.
Expand priority. The priority of an Expand message. The Expand priority is based on the
priority level of the application process that created the message, unless the
SETMODE 71 procedure is used.
fabric. A complex set of interconnections through which there can be multiple and (to the
user) unknown paths from point to point. The term fabric is used to refer to the X or Y
portion of the ServerNet system area network (SAN); for example, the X-fabric.
Fast Ethernet ServerNet Adapter (FESA). The FESA is a single-port adapter that provides
connectivity between NonStop S-series servers and Fast Ethernet 802.3u LANs. It
supports 100 Mbps and 10 Mbps Ethernet data transfer rates on NonStop S-series
servers.
Fiber Optic eXtension (FOX). A term used to describe various fiber-optic extension
products. The FOXII subsystem is provided for Cyclone systems, the TorusNet vertical
subsystem is provided for NonStop K-series servers, and the ServerNet/FX adapter
subsystem is provided for NonStop S-series servers. See also Expand-over-FOX line-
handler process and FOX ring.
FIRMUP. A diagnostic task that is used to update the copy of the pSOS imbedded kernel
that is kept in the SWAN concentrator communications line interface processor (CLIP)
memory.
FOX. See Fiber Optic eXtension (FOX).
FOX cable neighbors. Two FOX systems that are directly connected by a physical FOX
fiber optic cable. See also Fiber Optic eXtension (FOX).
FOX monitor process. The manager process, called $ZZFOX, for the ServerNet/FX
adapter subsystem on NonStop S-series servers. $ZZFOX is responsible for
maintaining configuration information about a FOX ring.
