Erm...I could have printed that for under 10k using our copiers which where procured through a government purchasing framework in less than a day. I would have happily been paid 35k to do it to.

We've carried out some initial benchmarks on a production cluster running Windows Server 2016 Hyper-V with IOMeter and other various tools, and its looking pretty horrendous.
We are seeing disk io performance halve in VMs. Numbers like 60,000 IOPS and 2GB/s dropping to 30,000 IOPS and 1GB/s.
We're also seeing CPU utilisation related to disk IO almost triple on the hosts.
Dell PowerEdge R730's with dual Intel Xeon E5-2697 v4, lots of 10Gb NICs. Same VM just moved between unpatched and patched (plus new bios) hosts.
Storage is all network based which is the killer for us
I own a Tesla Model S and use autopilot daily. It's perfectly safe, very relaxing and a great safety feature.
Tesla make it very clear you must keep your hands on the wheel, right from the hand over when you pick up the car, to the warning/T&Cs when you enable autopilot, which is disabled by default, and in the manual. It also reminds you every time you activate autopilot, and regularly while driving.
Brown ignored all this and was supposedly watching a movie. His crash was human error. Just the same as it would be my fault if I crashed driving 150mph on a windy country road (something that happens daily, yet doesn't make the news) - I used the car inappropriately.
Tesla are dragging the auto industry into the future. Some people don't like change. And most companies don't like competition.
As others have said you should be running Windows natively and virtualising Linux. I wouldn't go for the two machine approach either.
Buy your high spec machine, install Windows 8.1. Enable Hyper-V and setup a RHEL/SUSE virtual machine. Hyper-V's overhead is about 10% so with a couple Xeons your Linux VM is still going to be plenty fast enough!
No one can answer your question until you know what you're migrating too.
It sounds like this project isn't being run particularly well to be honest. As others have said you need to go back to basics: Why are you changing email system? What's wrong with the current system? What new features do you need?
You need to do a full audit of your current system: Number of mailboxes? number of items in each mailbox? Size of each mailbox? Number of emails sent/received per day and per hour? Etc
Plus you need to think about disaster recovery, archiving and legal issues etc. Are there any data protection issues with using cloud based services? which country would the data be stored in? Do you need to archive email? How long for? Etc etc
Re: Think this will affect you?
"...You've very little to lose, and a lot to save..."
You guys crack me up. Seriously what companies do you deal with?
Can you give me a quote for converting all our databases from MS SQL to MySQL, redeveloping all our access and C# front ends, bespoke applications, web services, sync services that connect our databases to exchange, migrate our SharePoint portals etc etc etc etc etc. Also can you include training for thousands of people on OpenOffice and the alternatives for the Adobe Photoshop, Indesign, Premiere, After Effect etc etc etc
It would cost a few million £'s and a few years development to move to Open Source....makes license increases look like small change.
and personally...i've never seen a open source environment that's as feature rich and slick as a well setup Microsoft environment
I'll get my coat..
If you ignore the "modern UI" and look at the rest of the OS Windows 8 is a big improvement over Windows 7. It's significantly faster for a start, better multi monitor support, the ribbon UI in explorer, consolidated file operations, ISO/VHD mounting in explorer, defender has AV built in, the are some cool networking improvements, the lock screen, updated taskmgr, Hyper-V, ARM support in the RT version, USB3 support, WDDM 1.2 etc etc
There are some major and stupid issues with metro (or whatever its called today) though...far to many things are hidden, the all apps screen is a complete mess and shutdown/sleep/restart is way too hidden.....
But overall I'd rather run Win8 than Win 7, and the first start menu screen with all the live titles is great.
Plus from an enterprise perspective it's going to make deploying and managing tablets a piece of piss. No more iPad nonsense!
