Whats new in VMware Fault Tolerance 6.0

VMware Fault Tolerance (FT) in vSphere 5.5 is one of those features you would love to use but because of its vCPU limitation it was not really helping to protect the Mission Critical applications so for many its left behind. With vSphere 6.0, VMware broken the limitation of a single vCPU for Fault Tolerance, a FT VM now Supports upto 4 vCPUs and 64 GB of RAM. With vSMP support, FT can be used to protect your mission critical applications. Along with the vSMP FT support, let’s take a look at what’s new in vSphere 6.0 Fault Tolerance(FT).

Difference between vSphere 5.5 and vSphere 6.0 Fault Tolerance (FT)

Difefrence between FT 5.5 amd 6.0

One thing to be aware of with VMware FT is that this feature does not monitor the application its still only virtual machine protection so you still need to think about the application and how it will be protected.
