Provide Uniform High Availability at a Lower Cost
Deliver high availability across your entire virtualized IT environment without the cost or complexity of traditional clustering solutions. VMware HA provides cost-effective high availability for any application running in a virtual machine, regardless of its operating system or underlying hardware configuration. VMware HA eliminates the need for dedicated stand-by hardware and additional software.

Protect Your Infrastructure from Multiple Sources of Failure
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.
