HP LeftHand P4000 Virtual SAN Appliance Software - Manual (Page 109)

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.
Virtual Managers
A Virtual Manager is added to a management group, as shown in Figure 44 (page 109) , but is not
started on a storage system until a failure in the system causes a loss of quorum. Unlike the Failover
Manager, which is always running, the Virtual Manager must be started manually on a storage
system after quorum is lost. It is designed to be used in two-system or two-site system configurations
which are at risk for a loss of quorum.

Configuration Summary overview
The Configuration Summary provides an easy-to-use reference for managing the size and optimum
configuration of your SAN. The first time you create a management group, a configuration summary
table is created that resides immediately below the Getting Started Launch Pad in the navigation
window. Subsequent management groups are added to this Configuration Summary, shown in
Figure 45 (page 110) . For each management group, the Configuration Summary displays an
overview of the volumes, snapshots, and storage systems in that management group. The Summary
roll-ups display configuration information and guide you to optimal configurations for volumes and
snapshots, iSCSI sessions, and the number of storage systems in the management group and in
each cluster.
Summary roll-up
The summary roll-up provided on the Configuration Summary panel is organized by management
group. Within each management group is listed the total number of volumes and snapshots, storage
systems, and iSCSI sessions contained in the management group.
