VMware white paper VMware® Fault Tolerance (FT) provides continuous availability to virtual machines, eliminating downtime and disruption — even in the event of a complete host failure. This whitepaper gives a brief description of the VMware FT architecture and discusses the performance implication of this feature with data from a wide variety of workloads. 1. VMware Fault Tolerance a rchitecture The technology behind VMware Fault Tolerance is called VMware® vLockstep. The following sections

VMware white paper It is recommended that FT primary virtual machines be distributed across multiple hosts and, as a general rule of thumb, the number of FT virtual machines be limited to four per host. In addition to avoiding the possibility of saturating the network link, it also reduces the number of simultaneous live migrations required to create new secondary virtual machines in the event of a host failure. 2.8.

Kernel Compile This experiment shows the time taken to do kernel compile, which is both CPU and MMU intensive workload due to forking of many parallel processes. As with the previous experiment, CPU is 100 percent utilized and thus FT performance is dependent on how well the secondary can keep pace with the primary. This workload does so

VMware white paper 4. VMware Fault Tolerance Performance Summary All Fault Tolerance solutions rely on redundancy. Additional CPU and memory resources are required to mirror the execution of a running virtual machine instance. Also, some amount of CPU is required for recording, transferring, and replaying log events. The amount of CPU required is mostly dependent on incoming I/O. If the primary virtual machine is constantly busy and resource constraints at the secondary prohibit catching up,
