XenServer vs ESXi
-
Unfortunately I don't know what the MSP has provided or offered, I was simply told that "they / we" will be virtualizing all of our critical servers to ESXi (of which I later found out the proposed version was Essentials). When I heard this I had a real serious discussion with my boss about not incorporating yet another Hypervisor. Our MSP has already setup Hyper-V which is only running 2 VM's on our 2nd DC, and they run like shit. I don't want them creating and building a solution that will result in more of this.

So you have XenServer doing non-essential stuff? You have Hyper-V doing something else? Then they want to bring ESXi in? You really need to get a new MSP something is really wrong with this picture.
As for Hyper-V sounds like something is wrong if it is running slowly. Our Hyper-V systems are running great.

I would say that generally I want an MSP that supports me rather than one that I have to adjust to support them.
-
The trouble as far as I can tell with the Hyper-V setup is that our MSP sold it just to sell it, rather than "Oh hey spend X and build a proper Hypervisor, we'll just use your secondary DC to run these machines"
Which "OK" it works but one of these VM's runs a CPU intensive process, and in only able to use 4CPU's because of the limitations of the host hardware.
If I moved this to "my" (and I use my liberally) XenServer I could allocate 12 cores to it, and 32GB of memory (if we bought more to add into the host) and the team that uses it would never have a complaint.
Its the poor proposals after another that are getting to me. It's just not my place to start looking for another MSP... even though I've considered it.

Expense is the big one. You would be spending a significant amount of money on licensing and getting no benefit from it. Unless of course the benefit is the MSP is going to support it... in that case I would ditch them and look at an MSP who can support what you have not what they want you to get.
Very important that your MSP either not significantly drive your decision making (they always have to a little, no MSP can truly do absolutely everything absolutely equally, but within reason) or that you calculate the amount that they do into the valuation of their services. If they require that you run only what they know, that might allow them to lower the cost that they charge you (but that needs to be verified of course) but it causes things to cost you more as you can no longer pursue the technology that is best for your business but instead the ones that are best for your MSP. And MSPs generally choose this technology based on profit margins or ease of support (or lack thereof so that they can sell more support) rather than on being cost effective to acquire and support for the customer. So it can create a cascading effect of cost if you are not careful.

What advantages does the MSP propose that ESXi will provide the XenServer can't?
Likely that they know the one and aren't even aware that the other exists.
-
My guess is that the MSP is not functioning as an MSP here but as a VAR - a reseller and so the recommendation is purely one of sales and no consideration for business needs has been included.
-
That Vm that is CPU intensive is constantly being asked to generate rather large database reports sequentially upwards of 12-30 at a time.
Having only 4 CPU's it can only run 4 jobs, to top it off it nearly maxes out is memory usage during these period so performance tanks even more

I agree, nothing wrong with HyperV and it should be running just fine. If the MSP can't get the systems that they have recommended in the past to work, based on that track record, why would the boss even remotely consider letting them replace what you've shown does work for something more expensive from a vendor that is having issues supporting what they recommend?

So the issue is that the server put in was too small? HyperV is not causing as issue? Who did the capacity planning? Can more memory be added, another CPU, a bigger CPU?

What manager kept them after they installed processing onto a DC? Who is overseeing the vendor management?

The server was/is our acting 2nd on site DC, we have 4 in total.
The board is maxed out with memory. I'm not positive how the conversation went when the idea came up to do this but I have a feeling it went like " We need X,Y,Z and need to spend a little as possible"
The result was something that runs horribly. Oh our On-Site Exchange is hosted on this same host, works "fair" for what it does but seems like its over scaled. And is still sluggish in basic operations.

Here is the big question... is it your job to care about the company or not to care? It's an honest question. Lots of companies would say that it is not your job to be involved. Others would be furious to find out that you knew an MSP was screwing them over and that a manager was letting it happen and not even pushing back for reasonable solutions and you didn't go up the chain to let someone know. Figuring out what your role in is key.

Red flags. Red flags everywhere.

I was asked to make a compelling case.
That to me means I should care.
But to what level. . .

What do you mean by "installed processing onto a DC"? I know little about Hyper-V, but we used our existing DC for our ESXi host and it went fine. Isn't this the same?

You were asked by someone who was willing to also make a compelling case for VMware? Given that there is no known advantage to the VMware route, it is hard to know what constitutes a compelling case. XenServer is known to work, known to be easy, already in the shop... to me that's a slam dunk right there in the light of "no advantages to switching."

That would be the same, and it would be a terrible practice, and it consumes one of your licenses and/or it is a license violation. HyperV is never meant to be used that way and is licensed in such a way that you would never have to. Can you? Sure. Should you, definitely not. The "host" is supposed to do nothing but managed HyperV. If you use your "two VMs" licenses from Windows, then you aren't allowed to have the DC on the host at all, that's another use license.
-
Unless by "used an existing DC as the host" you mean that you removed the DC, made the system into a host instead of doing a clean install first, and then installed the DC into one of the guest VMs. That would be "fine", but you should always clean install before making something into the HyperV host, it only takes a few minutes and ensures that you have a pristine host platform.
