VMware High Availability (HA)

VMware HA provides pervasive, cost-effective failover protection within your virtualized IT environment.

Protect applications with no other failover options and make high availability possible for software applications that might otherwise be left unprotected.
Protect applications from OS related failures by automatically restarting virtual machines when failure is detected (experimental mode).
Establish a consistent first line of defense for your entire IT infrastructure.
Automatically Restart Virtual Machines
VMware HA is a feature-rich product that continuously monitors all physical servers in a resource pool and restarts virtual machines affected by server failure.

Monitors and detects virtual machines for “guest OS” failures and automatically starts virtual machines after user-specified intervals.
Detects server failures automatically, using a “heartbeat” on servers.
Restarts virtual machines almost instantly without human intervention on a different physical server within the same resource pool.
Continuously monitors and chooses the optimal physical servers within a resource pool on which to restart virtual machines (if used in conjunction with VMware DRS).
VMware HA is included in VMware Infrastructure Standard and Enterprise editions. Get more information on the VMware Infrastructure editions.
