Configuration Parameters

This section discusses the maximum limits for HMP HyperFabric

configurations. There are numerous variables that can impact the

performance of any particular HyperFabric configuration. For more

information on specific HyperFabric configurations for HMP

applications, see “HMP Supported Configurations” on page 33.

• HyperFabric is only supported on the HP 9000 series servers, UNIX

servers and workstations.

• HMP is supported on the HF2 adapter, A6386A only.

• The local failover configuration on HMP is supported only on the

A6386A HF2 adapters.

• Although HMP works with A6092A HF1 (copper) adapters, the

performance advantages HMP offers will not be completely realized

unless it is used with A6386A HF2 (fiber) adapters and related fiber

hardware. See Table 7 on page 29 for details. The local failover

configuration on HMP is supported only on the A6386A HF2

adapters.

• Maximum Supported Nodes and Adapter Cards:

HyperFabric clusters running HMP applications are limited to

supporting a maximum of 64 adapter cards. However, in local

failover configurations, a maximum of only 52 adapters are

supported.

In point-to-point configurations running HMP applications, the

complexity and performance limitations of having a large number of

nodes in a cluster make it necessary to include switching in the

fabric. Typically, point-to-point configurations consist of only 2 or 3

nodes.

In switched configurations running HMP applications, HyperFabric

supports a maximum of 64 interconnected adapter cards.
