WHITE PAPER
HEWLETT-PACKARD'S SOLUTION FOR
HP TO IBM COMMUNICATIONS
Introducing HP SNAplus
Hewlett-Packard first introduced IBM connectivity products
in the late 1970's. As IBM networking standards evolve, HP
continues to add new capabilities to provide co-existence of
HP systems in IBM environments. The SNAplus project allows
HP to continue offering one of the most comprehensive IBM
connectivity offering in the industry.
Customers today, are evaluating alternatives to mainframes
which provide significantly better price/performance, lower
support costs and scalable growth. This trend has meant a
shift in the networking solutions. In many cases new system
must be tightly integrated with the mainframe environment,
since users still need access to applications remaining on
the host system. SNAplus offers a range of new capabilities
and products to meet the growing needs of this rightsizing
trend.
Features
HP SNAplus provides the following key components:
o Client/Server Architecture - The client/server
architecture connects distributed users with
applications that are on multiple systems on a LAN.
Multiple servers provide the additional benefit of
redundancy, as well as load balancing.
o Applications and APIs - Application Programming
Interfaces (APIs) are provided for developing
distributed applications, programs to interact with
existing host applications and general services for
application programs.
o Interactive and Batch - Interactive and batch
communications are provided for terminal and printer
emulation and batch data transfers providing a key
IBM operating environment for mission critical
applications.
o Network Management, Support and Consulting Services
- Centralized network management capabilities
provide for configuring, managing and
troubleshooting the network. In addition to
OpenView connectivity, communication with NetView is
provided through data-link alerts, response time
alerts, and user application alerts. HP also
provides worldwide support and consulting services
for designing, implementing, and maintaining the
network.
Benefits
HP SNAplus provides the following customer benefits:
o Increased performance - Client/server architecture
improves performance of clients by offloading the
communications protocols from the client to the
server machines. In addition, load balancing across
multiple servers can provide increased performance
in environments where host access traffic is heavy.
o Investment protection - The HP SNAplus product line
provides for future growth and allows more efficient
development of new capabilities and functionality.
SNAplus offers a smooth migration path providing
existing HP to IBM users a clean way to update to
the new generation of products.
o Improved service and decision making - Standards-
based products, such as HLLAPI and Motif, provide
for efficient development of customized software to
fit the business requirement.
o Seamless integration of HP systems into an IBM
environment.
o Ease of use - Improved ease-of-use results in
improved productivity and reduced operations.
- For operations - The Browse facility, NetView
alerts, dynamic tracing, and menu driven
configuration are network administration and
management tools which will help improve customer
service and support tasks.
- For application developers - HLLAPI, APPC, and
LUA API's combined with a Motif interface allow
customers quickly and efficiently to develop and
maintain software products.
- For business administrators - HLLAPI, Graphical
User Interface (GUI) and Token Ring will improve
productivity through network speed and easy to
use interface.
Release 1, has been available since April 1992 for the HP
9000 Series 300, 400, 700, and 800. This release included
three products: HP-UX SNAplusLink, HP-UX SNAplus3270, HP-UX
SNAplusAPI.
Release 2, available March 1 1993, will include SNA over
Token Ring, SNA over X.25 (or QLLC) support, NetView API,
LUA API, RJE, Motif Graphical User Interface for color 3270
and 3179G Graphics support.
Release 3 of the HP SNAplus product family will include
support for CPI-C, 16 bit character support for Asian
languages and HP server support for PC clients. Watch for
availability in late 1993.
Remaining phases of SNAplus being investigated include APPN
End Node support and the integration of the HP 3000 Series
900 Business Systems which offer extensive SNA capabilities
today.
HP-UX SNAplusLink for HP 9000 Series 700 and 800
Release 1 of SNAplusLink provides the data link control
layer for SNA secondary communications across SDLC
communication links to host or peer systems. SNAplusLink
bundles the link and client/server in one product. The link
and client/server are available on the HP 9000 Series 700
workstations in addition to the Series 800 multi-user
system. The Series 300 and Series 400 workstations can act
as clients by using the Series 700 or Series 800 as servers.
The maximum number of LUs for the gateway and link has been
increased to 254 per system for both the stand alone and
client/server configurations.
SNAplus Release 2 adds SNA over Token Ring capability to the
SNAplusLink product. Now you can run both SNA and TCP/IP
traffic over a single Token Ring link concurrently. Since
Token Ring is a LAN technology, this also increases
performance compared to running SNA over SDLC lines. The
SDLC technology could run at a maximum of 64Kbps. Token
Ring can run at both 4 and 16Mbps.
SNAplusLink has also been enhanced with SNA over X.25. This
allows SNA traffic to be sent over an X.25 network via a
native solution. Both SNA and TCP/IP traffic can be sent
over the X.25 network concurrently. QLLC technology is used
to accomplish the SNA over X.25. This solution is excellent
for customers wishing to move toward standards based
networking and off their proprietary SNA backbones.
HP-UX SNAplus3270 for HP 9000 Series 300, 400, 700, and 800
HP-UX SNAplus3270 Release 1 offers a high function 3270
emulator with the following features:
o Support for multiple concurrent sessions
o IBM 3278/3279 display emulation supports screen
models 2, 3, 4 and 5, color remapping, keyboard
remapping, multiple sessions, status line messages
and local copy capabilities
o IBM 3287 printer emulation to printer or file (LU1
and LU3)
o IND$FILE provides file transfer to MVS/TSO, VM/CMS
and CICS
o HLLAPI, a programming tool to automate tasks that
require a series of actions
o Response Time Monitor to evaluate host
responsiveness
o NetView 3270 User Alerts to provide a communications
path between the 3270 user and the NetView operator
who can provide assistance from the host end
SNAplus Release 2 adds support for 7 colors and a Motif
interface to SNAplus3270.
HP-UX SNAplusAPI for HP 9000 Series 300, 400, 700, and 800
HP-UX SNAplusAPI Release 1 is a high function SNA PU Type
2.0 or PU Type 2.1 node, allowing multiple concurrent access
to SNA host systems and SNA peer systems. HP-UX SNAplusAPI
allows application programs distributed across a network to
work together to accomplish a single processing task such a
querying a remote data base, copying a remote file, and
sending or receiving electronic mail. HP-UX SNAplusAPI
supports LU6.2 for basic and mapped conversations.
SNAplus Release 2 enhances SNAplusAPI with additional APIs.
NetView API has been added which consists of programming
calls to help customers integrate their applications with
NetView. NetView calls, and alerts can be initiated from
within applications for built in network management.
SNAplusAPI also includes LUA API. This is a collection of
APIs made up of Logical Units 0, 1, 2, and 3. LUA API makes
it possible for customers to gain access to printer and
terminal data streams. LU 0 calls offer customers the
ability to "roll your own" protocol, allowing lower level,
more intricate programming access for specialized
applications.
HP-UX SNAplusRJE for HP 9000 Series 300, 400, 700 and 800
Release 2 of SNAplus offers a new product, SNAplusRJE. This
product offers batch communications to an IBM host
mainframe. SNAplusRJE emulates an IBM 3770 terminal.
HP-UX SNAplus3179G for HP 9000 Series 300, 400, 700 and 800
SNAplus3179G is another new product offered at Release 2
under the SNAplus umbrella. This product emulates an IBM
3179G/3192G color graphics display station. Like
SNAplus3270, it offers support for 7 colors and the Motif
Graphical User Interface.
Configuration and Management
HP-UX SNAplus provides the following features for
configuring and managing the network to facilitate decision
support:
o Common User Access (a major element of SAA)
compliant Configuration, Manage and Browse programs
o Help screens for each menu option
o One integrated configuration program for all
services of HP-UX SNAplus
o Load balancing and fault-tolerant configurations
among multiple servers
o Browse program lets you view or print information
from log or trace files
o Communications with IBM's NetView through data-link
alerts, response-time alerts, 3270 user alerts, and
user application alerts
o NetView monitoring system gathers data for
administrative tasks such as operations management,
problem determination and performance management
Migration
HP customers who have purchased existing HP-UX SNA products
and have support contracts with HP, will receive an upgrade
to the comparable HP-UX SNAplus products at no cost. HP-
UX SNAplus3270 users will have the same look and feel of the
existing products but with additional functionality. HP-UX
SNAplusAPI users will have the same functionality, a
slightly different implementation, but additional
flexibility for communicating with other applications.
