Better fault tolerance This is due to multiple VM servers sharing a pool of resources, so if any hardware fails, the hosts can be run on other hardware. Vfusion especially Faster recovery from failure If snapshots are used and stored correctly, hosts can be back up and running in minutes. Achieve Higher Consolidation Ratios The advanced resource management and support for scaled up physical machines in VMware ESX and ESXi lets you run virtual machines at twice the consolidation ratio possible with other first-generation hypervisors. Take advantage of hardware systems with up to 64 physical CPU cores and 1TB of RAM, and run up to 256 virtual machines on a single host to facilitate large-scale consolidation and disaster recovery projects.
