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.
- 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.

Features
The following is a list of the key features of VMware HA. For a comprehensive list of VMware Infrastructure features download the key features summary.
Key Features
- Automatic detection of server failures. Virtual machines with VMware HA provide an easy to use and cost-effective failover solution to protect against server failures.
- Automatic restart of virtual machines. Protect any application with automatic restart in a different physical server in the resource pool.
- Virtual machine failure monitoring (experimental mode). Detect operating system failures within virtual machines through monitoring heartbeat information. Automatically restarts affected virtual machines based upon user-defined time intervals.
- Proactive monitoring and health checks. VMware HA helps users identify abnormal configuration settings detected within HA clusters. This keeps unhandled failure conditions and errors from happening more than once. The VMware Infrastructure client interface reports relevant health status and potential error conditions and suggested remediation steps.
- Scalable high availability across multiple physical servers. Support up to 32 nodes in a cluster for high application availability.
- Resource checks. Ensure that capacity is always available in order to restart all virtual machines affected by server failure. HA continuously monitors capacity utilization and “reserves” spare capacity to be able to restart virtual machines.
- Smart failover of virtual machines (when used with VMware Distributed Resource Scheduler). Automate the optimal placement of virtual machines to servers with best available resources after server failure.
