High Availability
Provide High Availability at a Lower Cost
Deliver high availability across your entire virtualized IT environment without the cost or complexity of 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 Server 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.
- 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.
- Detects server failures automatically, using a "heartbeat" on servers.
- Monitors capacity continuously to ensure space is always available to restart virtual machines in the event of server failure.
- Restarts virtual machines almost instantly without human intervention on a different physical server within the same resource pool.
- 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 Enterprise Edition and can be purchased as an add-on product to the Standard and Starter editions.
