Epyc vs Xeon - the RAM question

[Quartz]

I was just looking at Tyan and Supermicro motherboards and noticed that if RAM is the issue, then Xeon is the clear winner: Epyc motherboards seem to be limited to 4 TB of RAM whereas Xeon motherboards go up to 16 TB.

So there you have it; now the question is, why would you want 4 TB RAM, let alone 16 TB?

what are you looking to build?

I'm not; the question just interests me.

One reason you may want a lot of RAM is for SQL servers in VMWare / Hyper-V. They tend to use as much as you can give them.

But 16 TB?

They claim that with the various hardware and licensing savings, plus the security benefits, it saved them a fortune.

Interesting. But do you really mean VMs? Or Terminal Services? Because I'm not seeing how the former would really save in licensing costs.

No idea. It was a LOT of RAM. I suspect TS rather than true Virtual Machines.

When the first x64 Windows Server came out everyone jumped on it for TS. But 2 TB is 32 GB for each of 64 users. Wow.
