High Availability (HA) is a popular feature within vSphere. In many cases, the lack of High Availability is the key argument used against virtualization. Many IT professionals believe that in a virtualized environment, the failure of a physical server will affect all the applications and workloads running on that server at the same time.

High Availability (HA) is a popular feature within vSphere. In many cases, the lack of High Availability is the key argument used against virtualization. Many IT professionals believe that in a virtualized environment, the failure of a physical server will affect all the applications and workloads running on that server at the same time. VMware addresses this concern with a feature present in ESXi clusters: vSphere HA. In the event of complete server failure, vSphere HA provides an automated process for restarting the VMs that were running on an ESXi host at a time of the failure. Fault Tolerance (FT) is the evolution of continuous availability that works by utilizing VMware vLockstep technology to keep a primary machine and a secondary machine in a virtual lockstep. This virtual lockstep is based on the record/playback technology that VMware introduced in VMware Workstation in 2006. The vSphere FT process matches instruction for instruction and memory for memory to get identical results. This course discusses VMware Virtual Infrastructure High Availability options built in and available out of the box: vSphere HA and vSphere FT. These options help you provide better uptime for your critical applications. This course can be used in preparation for the VCP5 exam. However, it is not sponsored or authorized by VMware so does not fully satisfy the training requirements to achieve the certification.
