Overview
Tandem NonStop systems are characterized by their:
•
High availability and data integrity
•
Scalability from low-end to massively parallel operations
•
Outstanding price/performance
•
Large base of industry applications
•
Support for open connectivity (or interoperability)
Open connectivity facilitates the distribution of data and processing across
heterogeneous platforms.
Many customers require connectivity with IBM systems and networks. This enables
NonStop systems:
•
To be deployed in IBM installations and networks; for example, to handle critical
online transaction processing or to downsize or distribute mainframe solutions
•
To access applications and data on IBM systems; for example, where services or
legacy data are available only on IBM systems
Although IBM systems support communications protocols such as Open Systems
Interconnection (OSI) and Transmission Control Protocol/Internet Protocol (TCP/IP),
most networks of IBM systems still use IBM’s Systems Network Architecture (SNA).
Tandem NonStop systems provide support for SNA connectivity through the SNAX
access methods and SNAX application programming interfaces (APIs). See Figure 1-1
