IBM Hosts
IBM Hosts
NonStop S-series servers can connect with IBM host computers in several ways: by
emulating a cluster controller or host node (SNAX/APN), via a SDLC, a token-ring, or
an Ethernet connection. Additionally, a 3270 emulator lets users at HP 6530 family of
terminals use applications on an IBM host. Section 7, HP NonStop S-Series Systems
Network Architecture (SNA) Network Connections, describes products that support
connection with IBM hosts.
Batch Mode
Users and applications on NonStop S-series servers can communicate with IBM hosts
in batch mode using the Exchange products, which emulate various batch devices.
Exchange/RJE (remote job entry) emulates an IBM 2780/3780 binary synchronous
workstation or its equivalent. It supports connection with IBM hosts that use binary
synchronous communications. Exchange/RJE uses the Envoy or CP6100 IOP for link-
level functions.
Exchange/SNA emulates an SNA workstation, supporting simultaneous transmission
of multiple data streams. It supports connection with IBM hosts that use the SNA
protocol. Exchange/SNA requires SNAX/XF.
Cluster Controller Emulation
Two products enable NonStop S-series servers to communicate with IBM hosts as if
the NonStop S-series server were an IBM cluster controller: TR3271 and SNAX/XF.
TR3271 is an IOP that gives the NonStop S-series server the appearance of an IBM
binary synchronous cluster controller. With TR3271, applications on the NonStop
S-series server can communicate with the IBM host, or you can set up a passthrough
configuration with AM3270, allowing IBM 3270 terminals attached to the NonStop
server to communicate transparently with the IBM host.
SNAX/XF is an IOP that gives the NonStop S-series server the appearance of an SNA
cluster controller to an SNA host. Using passthrough configuration, SNA devices
attached to the NonStop S-series server can communicate with the SNA host.
Section 7, HP NonStop S-Series Systems Network Architecture (SNA) Network
Connections, describes SNAX/XF in detail.
