Users can supplement this software bundle by purchasing optional products, such as VMotion, as well as distributed services such as high availability (HA), distributed resource scheduler (DRS), or consolidated backup.
VMware Inc. released VMware Infrastructure 3 in June 2006. The suite came in three "editions": Starter, Standard and Enterprise.
Number of hosts managed by Virtual Center Server: 200
Number of virtual machines managed by Virtual Center Server: 2000
Other limitations were, for example, volume size of 64 TB with no more than 6 SCSI controllers per virtual machine; maximum number of remote consoles to a virtual machine is 10. It is also not possible to connect Fibre Channel tape-drives, which hinders the ability to do backups using these drives.
