Planning the Fabric
Hyper Messaging Protocol (HMP)
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
