SNAplus and Your Customer
December 14, 1992
1. INTRODUCTION
The purpose of this paper is to explain why HP undertook the SNAplus
project, how it will impact your customers, and provide you with the
information necessary to discuss SNAplus with your customers.
2. WHY HP IS MIGRATING THE SNA CLASSIC PRODUCTS TO SNAplus
Prior to SNAplus, our IBM connectivity solution came from multiple
vendors, was incomplete, and was not able to provide solutions for new
IBM networking technology.
With SNAplus, HP has chosen a strategic partner, with a vision similar
to our own, of the direction in which we need to evolve our IBM
connectivity products. This partnership will enable HP to provide the
networking solutions our customers need today, as well as future IBM
networking technology solutions.
The SNAplus solution on the HP 9000 platform will replace the
functions available with the old classic SNA products and will augment
these products with important new functions.
Migration to SNAplus will require customers who are running the
classic LU6.2 API to modify their applications. Substantial
differences exist in calling structure, parameters and transaction
program logic between the classic SNA LU6.2 API and the SNAplusAPI
interfaces. This is because each vendor implements the LU6.2
specification differently. (Documentation is available now to help
you and your customers to prepare for migration to SNAplusAPI.)
In presenting SNAplus to customers with LU6.2 applications, it is
important to help them understand why HP is moving to SNAplus and to
emphasize the added functions they will be receiving, at no cost
(provided they are on support contract), for example, SNA over Token
Ring, Motif interface, LU0,1,2,3 interfaces, EHLLAPI.
The existing, as well as new functions, provided by SNAplus over the
classic SNA products, are outlined in this document in order to help
you to explain the new functionality your customers will be receiving
with SNAplus and position the work which will be required to port
existing applications to SNAplusAPI.
