FT protects critical virtual machines against host and storage hardware failures. Prior to vSphere 6, FT only supported a single vCPU virtual machine. Support for vSMP (Symmetric Multi-Processing) now provides more use cases for utilizing FT to protect virtual machines, including the following:
- Protecting critical virtual machines with up to 4 vCPUs and 64 GB memory.
- Reducing the complexity of other clustering services.
- Protecting applications sensitive to the loss of TCP connections. FT failover maintains TCP connections between clients and the protected virtual machine.
The requirements for enabling FT protection for a virtual machine are as follows:
- 10 GbE network connectivity between hosts when protecting multi-vCPU virtual ...
