Vmware’s new vSphere 5 licensing model and pricing will upset some users, because it is going to change the machine sizing rules. The new structure of licensing and limitation is not based on the physical CPUs and physical RAM per server, it is actually based on per CPU with a limitation on vRAM per license for specific version of vSphere.
Memory limitation and prices for each vSphere edition are:
- Standard Edition: 24GB per $995 license
- Enterprise Edition: 32 GB per $2,875 per license
- Enterprise Plus: 48 GB per $3,495 per license
Means that, you can only share VRAM capacity among licensed servers according to the edition of vSphere. However, VMware calls this memory of law as a soft limitation. On the other side, you are able to use more memory than licensed in the VRAM pool as it will not prevent you from powering on your virtual machines (VM).
