I have setup FT on a VM in VMware 6.5. The objective was to have this server always available. However, after applying Windows updates when I reboot the server, the 'failover VM' does not seem to take over. Is this limitation of FT - that high availability is there only for unexpected hardware failure, not for software maintenance operations?<br />
<br />
Is MS Cluster the only solution in this scenario? Thanks.<br />

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
