vmware vSphere 5 licensing

[_techie_]

Hi,

 

Just getting into the 'mare that is vsphere 5 licensing

 

we have

4 vsphere 5 enterprise academic esxi hosts

1 vsphere 5 standard academic esxi hosts

1 vcenter server 5 standard

 

What is included in the support for the vsphere 5 enterprise renewal costs? Is this a 3 year or 1 year renewal?

 

Cheers
