http://www.gabesvirtualworld.com has a nice three part series titled : Hyper-V, not in my datacenter
http://www.gabesvirtualworld.com has this broken in to three parts.
When posting on my blog I try to stay as objective as I can. Although I’m a big VMware fan I try to look at other products with an open mind and not be biased, I found myself in doubt when creating a presentation in which I was comparing Hyper-V to VMware ESX. I wasn’t questioning myself whether I should or should not be objective, the problem was that I had trouble believing that the presentation I had created was an objective view of things.
Browsing through my presentation multiple times, I was convinced that what I’ve written about Hyper-V and ESX is an objective view on how things are at the moment, but still it looks like the only thing I’m doing is Windows-bashing. I decided to dedicate a blog post to it, so everyone can find out for them self if my points are valid. The big question of my presentation is: “Which is better for my datacenter, Hyper-V or ESX?”.
I’m looking at both hypervisors to see which features they have that would make them suited for running in the datacenter discounting nice features that I would rarely use. Here we go…….
I will put down my thoughts. In part 1 he talks about hardware, and how it applies to each, I have found in my testing that there is even a larger number of unsupported devices that does work with ESXi, it all depends on if you want supported products.
In part 2, the discussion of Guest OS support comes up, and I have to agree 100% Microsoft is shooting them self’s in the foot with this one, as 90% of the data centers out there have a large mix of OS’s, all with different versions of Service packs and such.
Part 2 also talks about over commit, and wow, look at the numbers, since we are a smaller shop, I have not had much need to get into over commit yet, and we are running ESXi only.
Part 3 talks about migration, and it looks like Microsoft dropped this ball totally on this, as they don’t even offer a hot migration option, end of story for me.
