For those of you who doesn’t know what is vSphere FT see the summary below.
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.
- Automatically trigger seamless stateful failover when the protected virtual machines fail to respond for zero downtime, zero data loss continuous availability
- Automatically trigger the creation of a new secondary virtual machine after failover, to ensure continuous protection to the application
This is a pretty good opportunity to let your voice heard.
