License - VMware vSphere 5 Essentials Plus Kit for 3 hosts
System unit with Windows 7 and vCenter software The

loads are small, the staff is inexperienced

Conditions

The 4th server is planned to be kept in reserve for prompt replacement of the failed one.

Question
Do I need to purchase an additional license to use the Mware VMware vSphere Storage Appliance

Answer 1

1. For starters: you won't install vcenter on Windows 7! Need 2008 server. (although you can use a tambourine ) - but naturally vmware is not supported
2. About loads - you need to calculate right away, especially disk load
3. If you use one server - why license for 3 servers
4. Storage - It is better to install on one with a large number of disks for performance or deploy on free NFS or iSCSI.
