Known Limitations
Known limitations in VMware Infrastructure 3 may constrain the design of data centers:
As of June 2008 limitations in VMware Infrastructure 3 version 3.5 include the following:
- Guest system maximum RAM: 64 GB
- Number of guest CPUs: 4
- Number of hosts in an HA cluster: 32
- Number of hosts in a DRS cluster: 32
- Size of RAM per server: 256 GB
- Number of hosts managed by Virtual Center Server: 200
- Number of virtual machines managed by Virtual Center Server: 2000
Other limitations exist, for example, volume size is limited to 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 driven tape-drives, which hinders the ability to do backups using these drives.

Famous quotes containing the word limitations:
“... art transcends its limitations only by staying within them.”
—Flannery O’Connor (1925–1964)
“Growing up means letting go of the dearest megalomaniacal dreams of our childhood. Growing up means knowing they can’t be fulfilled. Growing up means gaining the wisdom and skills to get what we want within the limitations imposed by reality—a reality which consists of diminished powers, restricted freedoms and, with the people we love, imperfect connections.”
—Judith Viorst (20th century)
