HP-UX SNALink and HP-UX Gateway/SNALink Technical Data
For HP 9000 Series 300, 400, and 800 Computer Systems Product Numbers
36592A, 36593A, 98173A, 98174A
HP-UX SNALink and HP-UX Gateway/SNALink provide communications between
an HP 9000 Series 300, 400, or 800 and an IBM mainframe or an IBM peer
system such as the AS/400. The SNALink manages the SDLC line to the
host/peer system and emulates the major features of an IBM 3274 cluster
control unit using the lower four layers of SNA.
[Figure 1 (HP-UX SNALink) Caption: none]
Node Type 2.0 (T2.0) for hierarchical connectivity and Node Type 2.1
(T2.1) for peer-to-peer connectivity are supported. Logical Unit Types
1, 2, 3, and 6.2 (LU1, LU2, LU3, LU 6.2) are supported as well.
The HP-UX SNALink is available in two environments: standalone and
client/server (gateway). The standalone environment provides access to
IBM mainframes or IBM peer systems for a single HP-UX computer that has
its own HP-UX SNALink. Running in the client/server (gateway)
environment permits access to the IBM systems from multiple HP-UX
computers on a LAN. These systems generally use a single HP 9000
computer with a Gateway/SNALink as a gate-way to access the IBM system.
The HP-UX SNALink products are used in conjunction with a service
product (for example HP-UX SNA3270, SNA3770, SNA3179G, or LU 6.2 API.
Please refer to the services data sheets for more information). A copy
of a service product must reside at each HP-UX client that is to
communicate with the IBM system through the server system.
Features
o SNALink allows the HP 9000 to emulate the major features of a 3274
cluster controller using SNA protocols.
o SNALink supports multiple Logical Session Units (LUs) as terminals and
printers concurrently. An entry level link is available on the
workstations. The number of configurable LUs per link varies by
processor type and the environment in which you are running:
- Standalone/Entry level
Series 300, 400: 2 LUs Series 800: 32 LUs
- Standalone/High Performance
Series 300, 400: 32 LUsSeries 800: 32 LUs
- Gateway
Series 300, 400: 64 LUsSeries 800: 64 LUs
o The SNALink products use powerful commands to monitor and control the
operation of the product.
o SNALink and G/W SNALink support Node Type 2.0 (T2.0) and Node Type 2.1
(T2.1). T2.0 allows connectivity to IBM System/370 or compatible
mainframes. T2.1 allows connectivity to peer systems such as the
AS/400.
o SNALink allows concurrent support of T2.0 and T2.1 when connected to a
mainframe in a boundary node configuration. The HP system can
simultaneously communicate peer-to-peer to the IBM mainframe through
LU 6.2 and also communicate interactively to the mainframe through
SNA3270 over the same link.
o The microprocessor-based SNA interface card offloads communications
line activity, resulting in zero CPU overhead on the HP-UX processor
when data is not being transmitted or received.
7
o The HP-UX Gateway/SNALink supports HP 9000 Series 300, 400, 700, and
800 as client systems running SNA Services and communicating with the
server processor over a LAN.
o An HP 9000 Series 300, 400, or 800 with HP-UX Gateway/SNALink
functions as a non-dedicated gateway. Depending on the customer's
specific application requirements, Gateway/SNALink easily operates on
a S/300, S/400, or S/800 while running other HP-UX applications.
o BSD Sockets is the de facto industry-standard interface between the
SNALink and the SNA Service products in a client/server environment.
o The SNALink and Gateway/SNALink products support line speeds up to 64
Kbps over switched or leased lines.
Functional Specifications
When used with HP-UX SNA3270, SNA3770, LU 6.2 API, or SNA3179G (for
S/300 and S/400 only), the SNALink and service emulate a 3274 model 51C
cluster controller and from 2 to 64 SNA LUs, depending on the model
processor and configuration type.
All printers and terminals supported by the HP 9000 Series 300, 400,
or 800 running HP-UX are supported by HP-UX SNALink and Gateway/SNALink.
SNALink allows communication with an IBM 370 or compatible mainframe
running VM, VM/XA, MVS/SP, MVS/XA, MVS/ESA, or DOS/VSE operating systems
and ACF/VTAM through an IBM 37X5 communications controller running
ACF/NCP. SNALink also allows communication with IBM midrange systems as
peers such as the AS/400, S/36, or S/38.
Up to seven SNALink products may be supported in a single Series 300,
400, or 800 system (depending on the number of card slots available).
This allows links to multiple IBM systems.
The SNALink supports synchronous modem speeds up to 64Kbps as
described below. SNALink requires synchronous modems that support the
following handshake signals: DTR, DSR, RTS, CTS, CD, RI. Modems must
also provide transmit and receive clocks for the SDLC interface and
ensure ground isolation between the communication systems. Some examples
of modems that are supported for SNALink are:
AT&T 201C
AT&T 208 BR
AT&T 209A
AT&T 500B

Message encoding: Supports NRZ (Non Return to Zero). NRZI (Non Return to
Zero Inverted) is supported on Series 800 systems only.
Customer Installation Responsibility
The products are customer installable. User installation aids, such as
automated installation procedure and an IBM host generation guide, are
provided to simplify the process. Additional assistance can be provided
by an HP System Engineer on a time-and-materials basis. For additional
information, contact your Hewlett-Packard Sales Representative.
