For small and medium business, branch offices and home offices only a limited number of computing resources are needed for server virtualization. To start a minimum of two hosts is needed. It delivers high availability. When three hosts are used, depending on the specifications of the host, quite some virtual machines can be hosted. 20 to 40 virtual machines on 3 64 GB hosts using VMware vSphere should be no problem if the storage array can handle the iops.
