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:
“That all may be so, but when I begin to exercise that power I am not conscious of the power, but only of the limitations imposed on me.”
—William Howard Taft (1857–1930)
“Much of what contrives to create critical moments in parenting stems from a fundamental misunderstanding as to what the child is capable of at any given age. If a parent misjudges a child’s limitations as well as his own abilities, the potential exists for unreasonable expectations, frustration, disappointment and an unrealistic belief that what the child really needs is to be punished.”
—Lawrence Balter (20th century)
