VMware Fault Tolerance (FT) is being one of my favorite feature but because of its vCPU limitation, It was not helping to protect the Mission Critical applications. With vSphere 6.0, VMware broken the limitation lock of Fault Tolerance. FT VM now Supports upto 4 vCPUs and 64 GB of RAM (Which was 1 vCPu and 64 GB RAM in vSphere 5.5). With this vSMP support, Now FT can be used to protect your Mission Critical applications. Along with the vSMP FT support, There are lot more features has been added in FT with vSphere 6.0, Let’s take a look at what’s new in vSphere 6.0 Fault Tolerance(FT).
