Planning the Fabric

Hyper Messaging Protocol (HMP)

Chapter 2 29

same process takes place when a resource is removed from a cluster.

However, DRU is not supported if you add or remove an adapter from

a node that is running an HMP application. This is consistent with

the fact that OLAR is not supported when an HMP application is

running on HyperFabric.

• Load Balancing: Supported

When an HP 9000 HyperFabric cluster is running HMP applications,

the HyperFabric driver balances the load across all available

resources in the cluster, including nodes, adapter cards, links, and

multiple links between switches.

• Switch Management: Not Supported

Switch Management is not supported. Switch management will not

operate properly if it is enabled on a HyperFabric cluster.

• Diagnostics: Supported

You can run diagnostics to obtain information on many of the

HyperFabric components using the clic_diag, clic_probe and

clic_stat commands, as well as the Support Tools Manager (STM).

For more information on HyperFabric diagnostics, see “Running

Diagnostics” on page 149.

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 supported on the HP 9000 series servers and

workstations only.

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

• The performance advantages that HMP offers are not completely

realized unless HMP is used with A6386A HF2 (ﬁber) adapters and

related ﬁber hardware. See Table 2-2 on page 20 for details. The local

failover conﬁguration of HMP is supported only on the A6386A HF2

adapters.
