XenServer vs ESXi

This system only works under a system where you are both ethical and reasonable. In any situation where you are not both, and the problem here could be one or the other or even both (the OP's scenario), this actually becomes a major problem.
At the very least, I hope that upper management would be aware that someone lower down was either blocking or at least presenting some pressure not to expose things to upper management. If the UM is okay with that, great. If not, they need to know, I would think.

So with some verbiage I stole from Scott here's my list of primary reasons to not use ESXi. (Ignore the bullets it reads better on my screen)
Citrix XenServer Facts (Advantages really…)
• We already knows it. (It’s already in use for Day-to-Day )
• It is incredibly easy to use.
• It is very performant and this has been shown.
o VM’s used by Interactive over a 3-5 day span producing sellable work only a few days after EagleXen was built and VM’s configured.
• Zero cost for everything, totally zero licensing if Citrix support isn’t required.
o Licensing is per Socket CPU and is perpetual (if needed)
o No critical functionality is lost if support is cancelled
• Full Paravirtualization Options for Linux workloads.
• Updates are also free forever, regardless of a support contract.
o Updating is also extremely easy with Free Tools (already configured)
• No overhead cost for license management.
• No salesman providing guidance. Built to suite our needs
• VM Backups are completely free and schedulable.
o Already configured and performed weekly on hardware we had in house*
• Far greater feature set than any possible VMware option.
o HA is free
o XenMotion is free
o XenMotion Storage is also free*
o Many more free features
• No scale limitations (within reason)
• Local support available (in Rochester)*
o Unlimited free forums support
o Paid options available with licensing through Citrix
• Minimal technical debt incurred.
o Hardware cost for required needsESXi vSphere Essentials Facts
• Publicly and extremely common Hypervisor
o Easily supported between different MSP’s as it’s “common”
o Designed for Enterprise businesses not SMB’s
o Licensing is priced for Enterprises not SMB’s
• Licensing Cost
o Maintenance is required to receive system updates
o Essentials allows use of appropriate hardware only
o Without a Plus plan or higher VMWare offers no support*
Essentials is a bare metal hypervisor that simply allows us to use our chosen hardware
o MSP’s / In-House IT must troubleshoot all issues
• Internal IT must learn ESXi vSphere Essentials management
o Troubleshooting procedures
o Backup systems
o Restoration steps
o Updating steps
• Requires 3rd party VM Backup Solution (Veeam / Unitrends.. etc.) -

• Publicly and extremely common HypervisorThey both are. That's not an advantage to either. Xen is what is used by Amazon, IBM, Rackspace, etc. The "big boys" for the most critical environments in the world. So from that perspective I'd call this a draw at best, in Xen's favour possibly.

Any reason to believe that XenServer is not easy to get support for or is that just based on people who use ESXi claiming such? I've yet to hear of anyone who struggled to get support for XenServer.

Is this meant to be a pro or a con? I'm not sure how you are planning to present this.

ESXi, like Xen, is a bare metal hypervisor. Essentials is a license, not a "thing."

VMware has great community support too. Open source is often great for this and is very good in Xen's case, but VMware's community is huge and just as good.

Just because a platform is used by Amazon, IBM, and Rackspace does not make it extremely common to IT.
No one "uses" Xen from those providers as they would "use" Xen installed locally.
XenServer is not an extremely common Hypervisor for the intents and purposes of an SMB (and many smaller enterprises).
-
Easy support as in (Our current MSP already uses this, therefore we don't have to look for support should we need it)
The enterprises item is specifically a negative as much larger companies (from all information I could find) with the aforementioned ones you put up are paying for ESXi functionality and licensing.
ESXi Essentials licensing allows you to use more than the maximum hardware of 1 CPU. Otherwise it's practically worthless without licensing but to run a few VM that can fit on a single CPU.

XenServer is not "easily supported between different MSP's" because it is NOT common as I previously documented. This mean it is harder to find an MSP to support it than it is to find an MSP to support VMWare. This does not mean ti is actually too hard to find a MSP to support it, but contrasting the two options this is most certainly a true statement.

o Licensing is priced for Enterprises not SMB’sBoth Xen and ESXi are designed with the enterprise in mind. I don't think this should really be included... it is basically saying that because Xen was designed for the SMB (which it wasn't) it is somehow a lesser product...
o Essentials allows use of appropriate hardware only
You should use supported hardware regardless I believe that XenServer has a HCL although it may be a bit out of date.
o Without a Plus plan or higher VMWare offers no support*
Essentials is a bare metal hypervisor that simply allows us to use our chosen hardwareXen is a bare metal hypervisor as well. XenServer is the distribution that is built on top of Xen. It is similar to VSphere for ESXi except already built into the operating system
o MSP’s / In-House IT must troubleshoot all issues
Same with XenServer?

There are two ways to look at it. Is it easier to find Vmware support? Yes. Is it so easy to get XenServer support that more support doesn't matter? Yes.
So as a relative use I think it is misleading. People have been doing this with Windows and Linux for years. Yes Windows shops are everywhere, but there is enough Linux support so that that's not a benefit of going to Windows. There is a threshold of "more support than you could consume as a customer" and both Linux and XenServer have that (at least in his market, maybe not in the wilderness somewhere.)
So yes, I agree. But it is important to not present it as a value.

Licensing priced for an enterprise is comparable to buying a car, you may have $200,000 to drop, but the next guy just wants 4 wheels and a steering wheel.
Why should I (we) pay more for a solution just because others are? Especially when there are other options for free.
Yes.. yes I know they are both bare-metail hypervisors.
Lastly
If we went with either paid solution (we not the MSP) would be more than likely to have to reach either support department* for help, unless its of a critical function at which point the MSP would come in to help.

If you are at the point of needing to go to a support department in either case, would the MSP be of any use?
-
@scottalanmiller .. Only if they had a Direct Dial to T3 support. Which they might if they are a partner of ESXi. But I don't have an answer to this.

Seems unlikely if they are struggling with basic HyperV installs
-
Ok sounds good. Agreed with your pricing info although I don't think that comes across in your list.
-
Well I didn't say they had it, I just wouldn't say they "don't have a T3 support number"
If I did then I'd be lying.

I'm of the opposite opinion, I prefer to not have management block upward concerns. I'm not a manager, but when I am I like companies that encourage people to take their concerns "up the stack." Not in a sneaky way but in a "we don't agree, let's take this up a layer and see what someone higher up thinks of our concerns."
Yeah I like this too. Though there does have to be a point where it does stop, and that's probably below the CEO or the Board.
-
I would say it depends. If you truly believe the CEO is sabotaging the company, you should go to the board. If you truly believe the board is, go to the investors. Make sure you are confident when you go to that level, though.
