Can you please compare scalability betwen V5 and older versions? i.e version 4
Your thoughts?

v5, scales far better, due to newer features like the balancing of storage datastores through Storage DRS.

There is 1 MAJOR difference between v5 and legacy versions you need to be aware of -> vRAM POOLS. You are limited in how much RAM you can use in your host against your vSphere 5 infrastructure. Your host may support 1TB (or more), but you can only use (be licensed for) an amt far less than that. (e.g. 96GB, per CPU socket) If you want to use more RAM on your host, you will need to add licensing (COST, COST, COST) Legacy versions of vSphere (4.1 and earlier) don't have this limiitation. They do limit CPUs and Cores though, whereas v4 does not have CPU limitation any longer. I know @hanccocka listed features that are in the 'whats new' doc...but there isn't any 'chart' that has a side-by-side comparison per sè by VMware. There are some 'cool' new features in v5, but not anything too cool for me to lose out on memory resources.

I had a typo above - I meant to say that v4 DOES "limit CPUs and Cores, whereas VERSION 5 (v5) does NOT have CPU limitation any longer".
