HP NonStop S-Series Systems
Network Architecture (SNA) Network
Connections
HP is a recognized leader in providing system interfaces to IBM Systems Network
Architecture (SNA) networks. These interfaces include batch and interactive SNA
device emulation, distributed online transaction processing (OLTP), and network
management services through NonStop NET/MASTER Management Services (MS)
software. The HP SNAX product family is the group of products that lets you
incorporate HP OLTP applications into an existing SNA network.
This section describes the products and facilities that allow HP NonStop S-series
servers and HP NonStop networks to communicate with IBM SNA systems and
networks. After A Brief Look at SNA on page 7-1 and Advantages of the SNAX Product
Family on page 7-4, the section discusses three types of interaction that SNAX
products support:
•
SNA Devices Using HP Applications on page 7-6
•
HP Devices Using SNA Applications on page 7-14
•
Cooperative Processing With SNA Systems on page 7-14
The remainder of the section covers the following topics:
•
SNA Subsystem Management on page 7-16
•
SNA Application Example on page 7-18
A Brief Look at SNA
To satisfy requirements for connection of dissimilar devices and sharing of resources
such as terminals, lines, and applications, IBM introduced SNA in 1974. Since that
time, SNA has been a major factor in networking: a large proportion of existing
networks include systems and devices based upon the IBM SNA model. SNA is a
layered architecture, with each layer corresponding to a specific set of communications
functions.
