O365 or Hosted Exchange while commonly accepted as "best practice" are, in reality (or at least my reality), not always the most economical solution. The "hidden costs" of managing Exchange on-premise (we're talking your wage/salary here) are often overhyped and inflated, especially if:
- The business already owns the hardware (hypervisor hosts)
- The IT Pro administering Exchange would be employed full-time/salaried regardless of keeping Exchange on-prem or outsourcing to O365/HE
We only have about 100 mailboxes and I've ran the numbers ($4/mo per mailbox for HE) on multiple occasions by myself and even with our CFO and it has never came out cheaper to move to O365 or even HE (vs an Exchange 2016 migration). Just another perspective for you. Tip of the iceberg here, really. Google "pros and cons of moving to O365" and you will find a LOT of information against it!

I agree with the others that you should use one big RAID10.
I won't say that you should fire your VAR, but you should not let a sales person design a system for you. Sales exist to sell products in order to make money. Their goal is for you to purchase their goods and/or services. Their goal is not to give you the best solution for your needs. You must look out for your environment and tell them what you need. If they won't sell what you need, then you can find a different VAR who will.

This seems to be their thing and that's how my VAR wants to set this new server up as well.So first things first... your server vendor and your VAR are not your friends nor do they provide RAID advice. They are sales people and they use random defaults for testing purposes. They do not have a "thing" as applies to you and what they use for testing is not a recommendation as to how you should use their servers. You honestly should never even know what they do because the first thing that you do when getting a server is blow it away and do a proper install - always, no exceptions. That includes wiping the RAID configs away and setting it up for YOUR needs, not for THEIR needs.
Also, never get advice from a VAR, ever. VARs are sales organizations. Get advice from IT, products from a VAR.

However, this is not a discussion for your VAR, at all. This isn't their expertise, there is no reason for them to know about this. They aren't IT people. If they just find this an interesting conversation, sure, show it to them. Nothing wrong with that. But there is no reason for your VAR to have any visibility into what you are doing. Salespeople don't design servers.

You'll want this under your belt as well...

I don't want to disrespect someone with more experience....Just read this bit. Fire him, now. This is an INTERN level of incompetence. The problem here is that he's just an incompetent salesman who is trying to trick you by implying he's an experienced IT pro. He's not. He's just a scumbag looking to take your money. That statement is beyond unprofessional and it means you can't trust him.... ever. This is such a degree of improper pressure and incompetence, walk away, right now.

My CTO is also a bit old-school and feels more comfortable having a separate physical server for email, just in case. But we did just get a brand new Dell SAN this year and we have a pretty killer virtual environment (vmware 6) and this is probably the direction we should be going. Maybe I will try to convince him again.. + expandWow, just wow. So things here...
- Your CTO is NOT old school, he's incompetent. Never use "old school" to mean "can't do his job and is clueless." We've virtualized critical workloads since 1964. What he's telling you isn't "old school" it's just "wrong."
- A CTO is not an IT job role, why is a CTO involved in this conversation?
- His "emotional needs" put the company in jeopardy and are very possibly for some person goal. This is the kind of thing we hear when someone is funneling money to a buddy at a VAR.
- Why do you have a SAN? Makes no sense given the rest of your environment.

Yours (and most companies) should have been moving to a fully virtualized environment 5-7 years ago at least. There are literally no negatives, only positives. Your CTO's "old school" mentality is most likely just rooted in stubbornness and ignorance. Do the research and present it to him. This is really a black-and-white issue at this point. There is some merit to still keeping a physical DC, but that's the only one I know of. + expandCrimson is all over this with good info. He is correct, there is zero excuse for not being virtual. This is 2017, we are a full decade past the last, lingering excuses and those were purely technical in nature. The only thing I'll disagree with here is that there is no excuse for a physical DC, that would suggest all kinds of things that are not accurate. No DC should be physical, ever. The only real "special cases" in not going virtual today are desktops and even that is almost gone.

It's important to not feel like this stuff is new. Virtualization goes back to 1964. Virtualization in the SMB / commodity space to the 1990s. And cloud to 2003. None of these are new or the future, they are the past and the here and now. Not that Alex thought that, I just didn't want that feeling to exist that someone who has been around for a while might not have kept up. These are "computer basics" and have been for generations.

He is simply WAY behind the curve here."Behind the curve" for perspective here... what he is telling you is based off of a 1998 Microsoft recommendation BUT MS was VERY clear when they made the recommendation to explain why they made it so that you would know when it did not apply any longer. And it stopped applying a LONG time ago. That he is repeating it suggests that he memorized a rule of thumb without understanding it which is a standard quick and dirty trick to sound like an IT pro when, in fact, he's just repeating something he heard. It means he doesn't understand what RAID is or how it works. RAID 5 was industry deprecated in 2009, and Dell is so strongly against RAID 5 that they pulled it from some of their interfaces to protect users from themselves and so that no one could claim that Dell supported it by including it as an option! That's how bad your VAR is.
