Compatibility Information and Installation Requirements

This section describes the requirements for installing version I.10.20.80 of the ATM link software on HP-UX 10.20.

OS Platform and Version Compatibility

You must have already installed HP-UX 10.20 (HP-UX 10.20 ACE for the B1000, C3000, J5000, and J7000 workstations) before you install the ATM software.

Software Requirements

The various software requirements for this release of ATM are described in the subsections below.

HP-UX Operating System Patch Dependencies

Table 4-2 “ATM HP-UX 10.20 Operating System Patch Dependencies” below lists the HP-UX 10.20 Operating System patches that ATM has dependencies on. Please note that only some of the patches are required, but we strongly recommend that you also install the other patches listed.

Contact your Hewlett-Packard representative to install the patch that is appropriate for your HP 9000 system.

High Availability Requirements

To use the High Availability feature for remote recovery, version A.10.10 or later of the MC/ServiceGuard software must be installed on all cluster systems running the software. As stated earlier, High Availability is supported on only HP 9000 servers (not on workstations).

Hardware Requirements

You must have an appropriate ATM adapter installed in the HP 9000 system. You can combine adapters, as long as they are all supported for the system. For a complete list of the corresponding ATM software for each ATM adapter, please refer to Chapter 2 of the ATM Configuration and Troubleshooting Guide (HP Part Number B1056-90007).




	WARNING! For T600 servers, the ATM adapters must be installed by qualified Hewlett-Packard personnel.

The "Maximum VCs per Adapter" also depends on the HP 9000's available RAM at system boot time—the driver checks the amount and limits the number of available VCs accordingly. Table 4-3 “Maximum VCs per Adapter Based on Available RAM” below shows, for each affected adapter, the amount of available RAM and the corresponding VC limit. Note that discontinued adapters are not shown.

Table 4-3 Maximum VCs per Adapter Based on Available RAM

HP ATM/155 Adapters (A5513A, A5515A, J2469A, J2499A, and J3420B)		HP ATM/622 Adapters (A5483A and J3573A)
Available RAM	Maximum VCs per Adapter	Available RAM	Maximum VCs per Adapter
Less than or equal to 32 MBytes	256	Less than or equal to 32 MBytes	256
Less than or equal to 64 MBytes	512	Less than or equal to 64 MBytes	512
Less than or equal to 128 MBytes	1024	Less than or equal to 128 MBytes	1024
Greater than 128 MBytes	2048	Less than or equal to 256 MBytes	2048
n/a	n/a	Greater than 256 MBytes	4096

You also can use the atmmgr show -c command to display the maximum number of VCs (called "VCCs" in the command's output) for an adapter.

Disk Space and Memory Requirements

The disk space and memory requirements are shown below (discontinued adapters are not shown).

HP-HSC bus.
- Disk space required to install: 8 MBytes.
- Disk space required to run: None.
- Memory space required: Table 4-4 “ Memory Requirements for Maximum Configured VCs—HP-HSC” below shows the amount of memory that is required if the maximum number of VCs are configured on each type of ATM adapter. Note that systems with less memory available can support fewer VCs. Also, other drivers present in the system share the memory resources, which might reduce the total number of VCs that can be opened.

System State at Installation

To install the ATM adapter, you must turn the system's power off. After you install the ATM adapter, turn the system's power on. Then, install the ATM software (the system is automatically rebooted as part of the installation process).

Software Installation Instructions

See the ATM Configuration and Troubleshooting Guide (p/n B1056-90007) for detailed information about installing the ATM link software.

Estimated time to install: 30 minutes (this includes hardware and software installation).

Known Compatibility or Incompatibility with Third-Party Products

The ATM software products operate with all UNI 3.0-, UNI 3.1-, and UNI 4.0-compliant ATM switches and equipment that comply with LAN Emulation over ATM versions 1.0 and 2.0 and MPOA version 1.0.
