11.0 HP StoreVirtual Storage VSA Installation and Configuration Guide (TA688-96141, September 2013)

Two-storage system configuration
A two-system configuration is the smallest possible redundant configuration. Automatic failover
between storage systems requires a Failover Manager. A two-storage system configuration contains
the following elements.
• Two StoreVirtual VSAs in a single management group
• A single cluster
• Two managers
• A Failover Manager added to the management group
NOTE: For more information, see “Failover Manager Overview” in the HP StoreVirtual
Storage User Guide, available on the following website:

Figure 2 Two-storage system configuration
Three-storage system-plus configuration
All configurations greater than two storage systems can be redundant, and do not require a Virtual
Manager or Failover Manager. A configuration greater than two storage systems contains the
following elements.
• Three or more storage systems in a management group
• Multiple clusters with as many StoreVirtual VSAs as desired in each cluster
• Running three or five managers, as appropriate
