Eliminate Downtime Due to Hardware Failures

vSphere Fault Tolerance (FT) provides continuous availability for applications in the event of server failures,  by creating a live shadow instance of a virtual machine that is in virtual lockstep with the primary instance. By allowing instantaneous failover between the two instances in the event of hardware failure, FT eliminates even the smallest chance of data loss or disruption.

Protect Your Applications Regardless of Operating System or Underlying Hardware

Protect any virtual machine including homegrown applications and custom applications that cannot be protected with traditional high availability products.

Simple to Set Up and Turn On and Off on a Per-Machine Basis

FT can be easily turned on or off for individual virtual machines. Since it leverages existing vSphere HA clusters, any number of virtual machines in this cluster can be protected with FT. Applications that require continuous protection during certain critical periods of time, such as quarter end processing, can utilize FT for higher assurance of availability during those time periods.

FT can be purchased as a component of the VMware vSphere Enterprise and Enterprise Plus editions and acceleration kits.

vCenter Server is required to use this feature.
