I believe they have 24GB of physical RAM (with the remainder going towards dom0 and the hypervisor).
- lsc 16y agoI find that... unusual. the hypervisor eats 64MiB, and few people use more than 1GiB in the Dom0.
- bbatsell 16y agoI believe the current Xen hypervisor uses about 128MB now, but yeah — I sincerely doubt it's out of strict necessity, but out of wanting to ensure not to overload each machine with too many nodes. They wouldn't bump down to 22GB because I assume their mobos are dual-channeled. Or, they're fibbing a bit by using that "on average" language, and they actually have more like 42 or 44 nodes, but wanted the nice round numbers for the marketing copy. Edit: Oh, I didn't check the username. I imagine you'd know better than I.
