I simply haven't used them before.
SATA drives? It's totally transparent to you. SATA is what is in desktops and laptops and nearly any SMB NAS device or SAN device. You'll normally encounter SATA at least ten to one over SAS. But other than the speed difference, they are the same drives. It's literally nothing but an "under the hood" protocol for the drives to talk to the RAID controller. Other than being listed as SATA instead of SAS in the RAID card's interface, you have no way to tell them apart.
Fair enough, they are much cheaper anyways. I'm going to lunch, be back after a while.

Four servers total, two for redundancy.
Oh.... all running Hyper-V, two as production and two for failover for those two?
Yes sir, that's the plan at least. I'm heading out to get lunch.

Chances are, NL-SAS will be what you want. But you have to see the actual prices to know.

Cool, now I follow.
So the next question is.... why Prod/DR failover design instead of just "cluster" design? If you treat them as clusters you can load balance and get better performance "every day" and only go to the limitations of the design in cases where something has failed.

I'm not against it at all; I just haven't set one up before.

Still running RAID-10 for the best performance?

Yup, that would only change if you were REALLY on the fence with RAID 6 and only needed "anything" to tip the scales. No significant changes in performance for RAID 10 would remain the choice 99% of the time (or more) if it was the choice with same speed SATA drives before.

@JohnFromSTL If you'd like to arrange a call, we can go over some of these specs in greater detail to help work out the solution. We here at xByte can definitely help lay some groundwork out for you. I don't see anything about memory requirements for capacity planning yet. Has it been mentioned?

I believe 192 GB to 256 GB would be adequate.
Please feel free to give me a call. I believe Lyndsie has my number in an email. Thank you.

How did this project go?
