MsSQL Server 2008 R2 Failover Cluster Installation on Windows Server 2008 R2 Enterprise x64 on VMware

Failover Cluster System Benefits

Protection at the instance level through redundancy
Automatic failover in the event of a failure (hardware failures, operating system failures, application or service failures)
Support for a broad array of storage solutions, including WSFC cluster disks (iSCSI, Fiber Channel, and so on) and server message block (SMB) file shares.
Disaster recovery solution using a multi-subnet FCI or running an FCI-hosted database inside an AlwaysOn availability group. With the new multi-subnet support in Microsoft SQL Server 2012, a multi-subnet FCI no longer requires a virtual LAN, increasing the manageability and security of a multi-subnet FCI.
Zero reconfiguration of applications and clients during failovers
Flexible failover policy for granular trigger events for automatic failovers
Reliable failovers through periodic and detailed health detection using dedicated and persisted connections
Configurability and predictability in failover time through indirect background checkpoints
Throttled resource usage during failovers
