> Linodes of the same plan are grouped together onto a host. We adjust the number of slots on each host according to its resources and hardware specification. On average, a Linode 512 host has 40 Linodes on it. A Linode 768 host has on average 30. Linode 1024 host: 20 Linodes; Linode 1536 host: 15; Linode 2048 host: 10; Linode 4096: 5.
Does this mean that a 512 host has 40*512MB = 20GB of physical RAM? If it is less than that, then where does the 512 figure come from?
- bbatsell 16y agoI 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.
