Disaster Recovery and Disaster Avoidance Planning for a Small Manufacturing Firm

As for Azure, AWS, Rackspace, etc - do they really need that?
A single VM can handle being an AD DC very well. It makes for a really nice, easy way to not only get your AD to be very resilient, it also moves the workload off premises along with the backups (if you put the FSMO roles there.) So you get the benefits of a hosted AD DC with the performance of a local - no need for local backups and you can keep using AD even if the local controller fails. Because it provides HA for AD and reduces backup needs, it can be a big win in some cases. Those cases primarily being if it tips the scales so that a second local server is not needed.

The Unitrends seems like a spend for nearly no reason in this case considering he already has the hardware for the second XenServer/XO option.
I agree. XO is so powerful (and free) that it is really, really difficult to justify doing much else.

Even without XO, if you go Hyper-V and Veeam, you'd save a bundle since he already has the hardware, and he'd be able to do everything you mentioned.

I suppose - how do you connect the Azure based AD back to the home base? Can you buy firewall based VPN, or are you thinking something like Pertino or ZT?

Same ways as any hosted, or off premises solution. Whether it is Azure, in a colo, down the street at the boss' house, at a second site... whatever solution you use for that you can probably use for the one on Azure. You can use an IPSec VPN, OpenVPN, Clientless SSL VPN, Pertino, ZeroTier or even (don't actually do this) just open the ports.

I've got a ghost writer...nice...
I am just crazy busy at work but this post reflects a fraction of what's on my plate right now. SO let me take a piece at a time.
We are running production VM's on that aging (but licensed) PowerEdge 2900. Do I need replacing that as my priority or perhaps look at the Starwind solution first? We are going to need more storage since we are adopting DocuWare.

Aging servers are bad things. That's when the risk goes way, way up. Nothing wrong with utilizing old stuff, but from the sounds of it you have one things that makes tons and tons of sense (someone jump in if I'm missing something big here) and that is....
Get one "nice" "new" server that will handle your entire workload without a problem and migrate everything to that. That's job one. Everything else is secondary and we can figure out the details after that. Getting to one, new server will dramatically lower your risk and make your job easier and is probably necessary no matter what else you decide to do. So getting that done and out of the way is a discrete, and very important first step. Once you have that and good backups, you can breath easily and move from being in a critical disaster avoidance mode to casually tweaking the environment for the best long term strategy.
-
I put "nice" and "new" in quotes because you definitely should not get new. Check out xByte (see their add on the right over there -----> ) and see how awesome refurb can be. That's all that we buy. Something like a nicer R510 might be all that you need. That will be very cheap. Get a warranty from xByte. So "new to you" and far better than what you have, but nothing crazy.
-
Going to a single server you likely want RAID 10, but RAID 6 can do fine. But likely you won't need more than four drives if you go NL-SAS or better, so RAID 6 wouldn't be an option yet. Go high on memory, it's cheap and almost always the bottleneck.
-
We will need the DPACK to know for sure, but an R510 is a monster compared to what you have and so much cheaper than the R700 series. The R510 can hold more storage than you could possibly need and is a very low cost chassis. Hard to go wrong with it. It's my favourite entry level Dell on the market. (The R720xd is my favourite mainline Dell.)

Got a ballpark number on that? How much storage does your fileserver use today? How much are you anticipating from DocuWare?

Checking out XByte now...good prices...would want something strong enough to run all of our VM's...then perhaps re-purpose the current T420 for the redundancy project.

I completely agree.
Call the XByte guys and get a quote.

They are great, we've been working with them for a few years now. And they are quite active here. @ryan-from-xbyte @SeanExablox @Lyndsie_xByte and more are around to help out.
-
I have not yet bought a server from them, but they were awesome when I needed some SSDs.
-
If DocuWare isn't as critical as everything else, you might, might consider storing it's data on a NAS unit if the disk it requires (same kind as everything else in the server) would be to expensive to put in the server itself.

We currently are still tower servers...so will look for the equivalent for sure.

This is the time to make the move. Seriously, even with just one server, racking is worth it IMHO. You generally get better equipment at better prices and everything is easier to deal with. Tell management that you are going to save a ton of money here and do some great stuff and part of the deal is you want a small 1/4, 1/3 or 1/2 rack and going to start upgrading stuff to more business grade as updates get made. Start with your server. You'll be very happy that you did. Doesn't have to be a cabinet, something small will do.
@JayRMS is our resident rack and cabinet expert, he can guide you and hook you up for something small for a starter rack system.

Just get a rack mount. You can still put it on a shelf...
I just spec'd one for you.

Note 1: That server is $5k and change. With two good procs, 64GB of RAM, and 16 terabytes of storage (in RAID10).
I picked the 4TB over a 3TB because XByte has them on sale at the moment.
Far cry from your quote and well under the $10k you mentioned.
You can drop 2 drives (for 12 TB in RAID10) and get two identical server for $10k.
Note 2: I did specify NBD parts only warranty on the assumption that you have a 2nd host being replicated to for fail over on hardware issues.
