9 Using specialized managers The SAN/iQ software provides two specialized managers that are used in specific situations. The Failover Manager is used in two-system and in Multi-Site SAN configurations to support automatic quorum management in the SAN. A virtual manager is added to a management group but is not started on a storage system until a failure in the system causes a loss of quorum. It is designed to be used in two-system or two-site configurations which are at risk for a loss of quorum. Definitions Terms used in this chapter: • Virtual manager-A manager which is added to a management group but is not started on a storage system until a failure in the system causes a loss of quorum. The virtual manager is designed to be used in specific system configurations which are at risk of a loss of quorum. • Failover Manager-A specialized manager running as a VMware guest operating system that can act as a quorum tie-breaker system when installed into a third location in the network to provide for automated failover/failback of the Multi-Site SAN clusters. • Regular manager-A manager which is started on a storage system and operates according to the description of managers found in "Managers overview" on page 149. • Manager-any of these managers. Failover Manager overview The Failover Manager is a specialized version of the SAN/iQ software designed to run as a virtual appliance in a VMware environment. The Failover Manager participates in the management group as a real manager in the system; however, it does quorum operations only, not data movement operations. It is especially useful in a Multi-Site SAN configuration to manage quorum for the multi-site configuration without requiring additional physical hardware in a site. Failover Manager requirements • Static IP address, or a reserved IP address if using DHCP. • Bridged connection through the VMware Console, or assigned network in VI Client. • Server on which to install the Failover Manager. • Only one Failover Manager per management group. • Only a virtual manager or a Failover Manager in the same management group, not both. • Failover Manager not inside a virtual Windows machine with VMware Server running. Minimum system requirements for using with VMware ESX Server • VMware ESX Server version 3.x • 1024 MB of RAM P4000 SAN Solution user guide 165
