VMware High Availability

VMware High Availability (HA)

Provide Uniform High Availability at a Lower Cost

Deliver high availability across your entire virtualised 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.

Protect your infrastructure from multiple sources of failure with high availability
Reduce IT costs and improve flexibility with server consolidation.
Decrease planned and unplanned downtime for improved business continuity.

VMware HA provides pervasive, cost-effective failover protection within your virtualised 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.
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.

resource_pool

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.
