Connectivity with IBM Systems
Connectivity with IBM Systems
SNAX access methods allow interoperability with most IBM and IBM-compatible
equipment, including:
•
Mainframes
•
Midsize systems, such as the IBM AS/400 series
•
Personal computers (PCs), such as the IBM PS/2 model
•
3270 terminals and printers
•
Automated teller machines (ATMs) and point-of-sale (POS) devices
•
Manufacturing systems and devices
Devices may be managed by either NonStop systems or IBM systems.
SNAX access methods support both traditional, hierarchical SNA and advanced peer-to-
peer networking (APPN).
Connections to IBM Systems
SNAX access methods support a wide range of physical connections to IBM systems
and networks, including:
•
Synchronous data link control (SDLC) connections, using RS-232, RS-449, V.35,
and X.21 electrical interfaces
•
X.25 packet-switching networks
•
Token-Ring networks (currently not supported on Himalaya S-series systems)
Applications Enabled for IBM Connectivity
A large base of applications already exists for NonStop systems, especially where
availability, performance, and security are critical. Many of these applications are
enabled to run across SNA connections using SNAX APIs. Table 1-1 illustrates the
variety of applications that are available from Tandem Alliance partners and that run
across SNAX APIs.
