Configuring HyperFabric
Configuring HMP for Transparent Local Failover Support
Chapter 498
How Transparent Local Failover Works
Consider a hypothetical HyperFabric configuration in a 4-node cluster,
with each node having two adapters (see Figure 4-6). In this
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.
Figure 4-6 A Configuration supporting Local Failover
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.
