Planning Hyper-V Storage using Windows 2012 R2 Guests

Hello all!

I have a particular implementation setup I am going for with my work network. I'm hoping to get some advice on a few things. We are currently running a single Win2003 Standard server that I am looking to upgrade. I am planning to move us to Win2012 Standard R2. I want to use two physical servers, each running Hyper-V hosts. On the first server one of the VMs will be my domain controller, DHCP, DNS servers. The first VM on the second physical server I will install a print server, file server, and maybe DFS to put the various shared locations into logical DFS namespaces. The second physical server will have enough drive space to store backups from client computers and (potentially) some system image backups of the more important computers. Each server will have a second VM that is a Hyper-V replica of the first VM. My overall goal is to have some high availability and a backup solution with redundancy. I may encapsulate the backup redundancy with external storage later on, but that is something else to consider down the road.

My main question is with regards to how I should setup my storage. The operating system installations themselves don't need to be hefty on the subject of storage. I won't be using much in terms of applications on the server. For backups, I'm making an educated estimation that I will start off with about 1TB (or less) of storage that will slowly grow to roughly 2 - 2.5 TB in size.

So the main question is:
- What kind of hard drive setup should I use to give room for a Hyper-V host, a primary VM and a replica VM, imagining that I will never need to go beyond the 3TB mark? Should I setup a couple small drives for the operating system and a larger one of the backups? Does this even matter since (presumably) the hard drives are going to be virtual?

Also, for what it is worth I plan to be using an ASAU 990FX Sabertooth R2.0 motherboard with a AMD FX-8320 CPU and 16GB of RAM. I don't think I will have issues with virtualization there, but if anyone can see a problem with that, please let me know.

Thanks to any and all who can provide some input. Forgive me if my question seems like a rookie question due to the subject. I haven't had to deal with server technology for years, so I am a bit rusty....and I've never worked with Hyper-V before. Searching the internet on the subjects have only half-answered some of my questions.

Again, many thanks in advance.
 
First off, you would likely be better asking this in the Business Computing forum as your question isn't simply about storage alone. It also had to do with your Hyper-V implementation.

You need to plan for future by getting a bit more storage than you may have initially planned. Data sprawl tends to increase over time, often more than anticipated.

Secondarily, I would probably recommend a different type of Hyper-V replication by putting the "backup" VMs on different servers. That way if one physical host died, you would still have all of your VMs intact on the other server.

Hardware wise, I would also go with Intel processors. They have more built-in virtualization options than AMD, especially since you weren't even using Opterons. Quite a number of them deal with performance boosts, so for now, they're better processors than AMD for work as virtual hosts.

Storage-wise, it would good to hear your usage scenario before recommending anything specific.

So bounce your question over at Business Computing for a bigger picture view of your situation.
