Two-Node Configuration
A two-node configuration is the smallest redundant configuration possible.
Automatic failover between nodes requires a failover manager. A two-node
configuration includes two VSAs in a single management group, with a single
cluster, running two managers and with a failover manager added to the
management group, shown in Figure 5.
For more information about the failover manager, see “Failover Manager
Overview” in the Multi-Site SAN User Manual, installed with the Centralized
Management Console as a PDF in the Documentation folder.
