Configuring HyperFabric
Configuring HMP for Transparent Local Failover Support
| How Transparent Local Failover Works |
| Consider a hypothetical HyperFabric configuration in a |
| with each node having two adapters (see Figure |
| configuration, there is no single point of failure, and all adapters that are |
| installed on any given node are configured as part of a card pair. |

The details of how HyperFabric handles failures of the adapters, links, switch ports, switches, and cables between switches in a cluster are discussed in the following sections.
