So wait, are slots 0 and 1 the 2.5" bays?
This R510 has 8x 3.5" drive bays. My SAS drives are 2.5" but I have the Dell caddie spacer things..
But you can't scrounge up eight drives, only six, that match?

The goal of using RAID is to provide the best reliability against when a disks dies.
If you can increase the chances of not being in a critical failure scenario, you'd take that approach unless you had some very clear technical reason to do something different.

Also never never never install the Hyper-V role from a bare metal installation of Windows Server. You are binding the licensing to the hardware of that server in this case.

My thinking is that I'd like the OS partition to be fast as possible, because why not.
Couple terminology pieces...
Your HV is what runs the system, not the OS. Hyper-V is an HV, Windows is an OS. Your OSes are in your VMs and will go on the big RAID array. Your HV alone, which is tiny and has no performance needs, is what will go on the SSD array.
They are not partitions, they are arrays. Partitions are a completely different, but very specific, concept.
Sorry, when I say OS in this case, I mean Hyper-V. I'm installing the bare-metal Windows Hyper-V 2016 hypervisor.
Right, Hyper-V is not an OS. Avoid that term.
Also there is more confusion about the product. Let's break this down.
Hyper-V is the Type 1 hypervisor, that means it is always bare metal. Never use the term "bare metal" with Hyper-V, because that is implied. It's redundant, but implies that you are confused and think that there is another option.
I just wanted to make it clear that I wasn't talking about the Hyper-V role in Windows.
Hyper-V is Hyper-V, not Windows. There is no such thing as Windows Hyper-V. There is Windows the OS, and Hyper-V the HV. The two are distinct, separate entities that never merge together. So you have to figure out if you mean you are installing Windows or installing Hyper-V.
I meant "Microsoft" instead of "Windows"
Hyper-V has a native installer ISO or it can be installed through a "helper" inside Windows. Those are purely deployment methods and not related to anything else here.

Scott is referring to installing the Hyper-V role. It's the "manage my server" or "add roles" feature that scott is referring to as "helper".

The iso is downloaded directly from the TechNet website, completely free even though it's listed as an evaluation.
The wording is so weird. They need to sort that out. . .

They won't it's mostly to trick people into buying licenses.

Good point.
Buy this completely free thing from us!

Right, but that doesn't imply that in any way. But calling your install Windows Hyper-V, instead of Hyper-V, implied that you were doing the role. Because the role is every bit as bare metal as the normal install, saying bare metal doesn't mean anything at all. But including the word Windows would mean a lot.

I have a lot of low capacity drives (like 300GB drives) but it's a mix of 10k and 15k and then some are dead and some aren't.

How is installing the Windows Hyper-V role on a Windows Server installation the same as installing the hypervisor? I thought that installing the role was worse than just installing the hypervisor since it's kinda sitting on top of the Windows Server OS and adds overhead or something.

Installing the role moves the previous bare metal installation to be above the hypervisor.
The windows server installation needs to be licensed and activated.
It binds the 2 VM's you can have to that hardware.
The part you are mixing up is that Installing the role on Windows (10 or Server 2016 or any Windows environment) is that it is taking that environment and transforming it into the Dom0.
The control domain.
So all of the limitations of that control domain are then brought into the hypervisor. Where as installing Hyper-V creates a completely free to use control domain at $0 cost to you, and without any of the restrictions from a Microsoft environment.

Dell will often reject consumer drives. Or any non-Dell drives.
What? What do you mean reject them? They will complain, but the drives work just fine... At least everything I have tested.

oh cool. I didn't know that.. I really need to do some learning..

Yeah I'm using a non-Dell SSD right now in this server and it's working fine.

Maybe I should see if I can install Hyper-V on an SD card.. I have an iDRAC with the card slot

No, don't do that. MS used to semi-support that long ago. Now they do not at all.

Depends on the drives and the controller. Often it won't work, sometimes it just partially works.

It's worse, because of licensing binding, and because it installs Windows bloat on top of Hyper-V. But it doesn't alter Hyper-V itself in any way.
