Expand-over-IP line-handler process
and outgoing Expand messages and packets going outside a FOX ring and handles
security-related messages within the ring.
Expand-over-IP line-handler process. An Expand line-handler process that uses the
NonStop TCP/IP subsystem to provide connectivity to an Internet Protocol (IP)
network.
Expand-over-NAM 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 or a SNAX/APN 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.
expert system. A software product that uses artificial intelligence in performing its tasks.
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 (ServerNet 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.
FASTPTCP. FASTPTCP is a Spooler print process that supports a wide-range of network
printers as well as printers connected to print servers and terminal servers. Protocols
supported include HPJetDirect, Lexmark, Microplex, LPD1179, Telnet, and “raw” TCP.
AWAN 3883/4/5 and 3886 models include enhanced support for FASTPTCP Telnet
protocol. Special support is provided for HP Tandem Transparent Protocol (TTAP) and
HP Printer Control Language (PCL) printers.
fault-tolerance. The ability of an HP NonStop server to continue processing despite the
failure of any single software or hardware component within the system.
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
