6 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 AT&T 2024A AT&T 2048A AT&T 2096A AT&T 2248A AT&T 2556 DSU AT&T 2596 DSU CODEX 2640 CODEX 2660 CODEX 2680 CODEX 2260 GTE LENKURT 56K DYNATECH LDM 22 Datatel DCP3080 8 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.
