After more than two years vSphere5 is ready! This will be a great release with many new features.
I look forward to working with Storage DRS, the new Virtual Storage Appliance, VMFS5 etc.
There will also be some changes regarding the licensing. vRAM is the new word. Some customers will need to buy more licenses but I think most will manage with what they have. Pretty much so sum it up Enterprise Plus gives you 48GB RAM pr. license. Take this into account when sizing your servers. a Dual Socket system with 96GB RAM would make sense.
