Regular managers and specialized managers

Regular managers run on storage systems in a management group. The SAN/iQ software has two
other types of specialized managers, Failover Managers and Virtual Managers, described below.
For detailed information about specialized managers and the how to use them, see
9 on page 165.

Failover Managers

The Failover Manager is used in two-system and in Multi-Site SAN configurations to support automatic
quorum management in the SAN. Configuring a Failover Manager in the management group enables
the SAN to have automated failover without requiring a regular manager running on a storage system.
A Failover Manager runs as a virtual machine on a VMware Server or on ESX and must be installed
on network hardware other than the storage systems in the SAN.

Once installed and configured, the Failover Manager operates as a storage system in how you add
it to a management group where it serves solely as a quorum tie-breaking manager.
