Full FT, like vSphere offers, would be the ability to completely yank power from one host and have the FT enabled VMs be functional with no loss of connectivity. I don't know how familiar you are with VMware's FT mode but it effectively sets up a second copy of the VM on your alternate host and constantly mirrors changes to it, right down to mouse movements. We have servers that don't support clustering but are effectively clustered using the FT capability. I know Hyper-V offers hot migration but last I was aware it would still drop connections in a failover scenario as the second host came online.

I have a 4 host cluster, 2 CPUs per host, with 2 hosts at 96GB and 2 at 48GB. I was planning on upgrading the 48s to 96 shortly but at this point I probably wouldn't be able to pay for the licenses needed to do that. With my 8 Enterprise licenses I'm already going to be licensed for only 256GB of my 288GB physical RAM so without any upgrade I'm going to need another CPU license just to use all the RAM I have now. If I want to upgrade? Might as well switch my Enterprise licenses for Enterprise Plus, with the corresponding per-socket purchase and support increase, or just forget about getting any more RAM for my hosts. vSphere 5 has a ton of new features, and several of them pay off big for my environment (especially things like datastore improvements, etc) but at what cost? Hyper-V isn't at the moment a viable solution – MelioFS from Sanbolic gets you hot migration and the Microsoft equivalent of working HA mode with relatively immediate failover but you still don't have a good solution for Fault Tolerant VMs like vSphere offers and their virtual networking is much more primitive. Windows 8 and Hyper-V 3.0, though, are now positioned to drive a stake into VMware's heart if they can develop a FT solution and perhaps get Sanbolic to drop their pricing a bit. ---- Jack Kramer Manager of Information Technology University Relations, Michigan State University w: 517-884-1231<tel:517-884-1231> / c: 248-635-4955<tel:248-635-4955> From: "Andrew S.

I work for/with two that do. For most workloads, RAM is more of a bottleneck than CPU, and in a heavily virtualized environment, you're going to see lots of RAM. We have 4 VSphere hosts that we just upgraded to 120GB of RAM -- quad core boxes... Plus two new ones with 144GB, also quad core.

I honestly can't see that many that would. I'm licensed for 6 proc's, meaning in my environment I could run a total of 144GB . I don't see this being a big deal for us in the SMB space. My hosts have less memory than the processor limit, as it is. Will this increase overtime? Likely.
