Moving to local storage?
-
@scottalanmiller I can do it if I power off the VM but not live. That basically means any maintenance I do on the host will have to be done outside business hours. The downfall is that it takes a decent amount of time to move the VMs since I have to move them to another datastore and host. Host 1 cannot see host 2's local storage. We are on 5.1 but could upgrade if you think it's different in a later version...

I am looking into licensing Storage vMotion to accomplish this but I'm not sure it will do what I want even if I have it. Maybe they'll give me a trail so I can test it out. Thanks for all the suggestions!
That feature is so expensive, consider moving to another platform to get that rather than paying that much for it.
Yeah, that is something I need to look into. Is it an easy transition from VMware to Hyper V?

Best practice is not to use live migration for maintenance anyway. I've seen billion dollar banks go down because they thought that they could do that and no one would notice.

Relatively, yes. Check out XenServer, too. Both Hyper-V and XS are very good alternatives.

Which do you prefer? As far as performance I've heard that Hyper-V is inferior to VMware and XenServer, but that was a couple years ago. Is there any truth to that?

A little, but rarely enough to notice. XenServer tends to beat VMware too. @dengelhardt say a 20% improvement going from VMware to XenServer. HyperV does fine. Your workload matters.
XenServer is the absolute best for Linux workloads. KVM tends to be the best for Windows workloads. HyperV and VMware are both good and rounded, but neither focuses heavily on performance in the same way. But all are pretty fast.

Which do I prefer? Well the one that works best for the situation at hand, of course
I have an emotional bias for XenServer. It is open source, comes from the Linux Foundation and I've been using Xen for a dozen years. I love it. I also find it by far the easiest to use and I like Xen-based clouds like Amazon and Rackspace.
But for tons of customers I know that Hyper-V often makes more sense. It's a good solution, free and very robust. And it is advancing quickly and interfaces really well with Azure (big surprise.)
Hyper-V has a robust backup ecosystem that XenServer lacks. XS is far easier to use and scale and has more built in tools.

Ok, well I am completely unbiased. VMware is the only one I've ever used so I'm comfortable with it. We are all Windows, currently run Lync Online, and have plans to run Sharepoint and Exchange Online in the future. We also use Unitrends for our backup software. Based on that it makes sense to me to steer towards Hyper-V. I know nothing about XenServer or KVM. It's honestly been probably 5-6 years since I've looked at Hyper-V too so I'm sure it's come a long way.

Unitrends actually uses KVM for its stuff
