- wmf 10y agoNothing special; each Xeon socket can provide 5 PCIe x8 slots. Don't try this in a 1U though.
- icpmacdo 10y agoBecause of the heat or something else?
- wmf 10y agoA 1U physically doesn't have room for 8 PCIe cards, although come to think of it you can fit 10 U.2 SDDs.
- sitkack 10y agoAnd those NVMe devices don't necessarily get dedicated access, they can definitely be over provisioned for access to PCIe
- jlgaddis 10y agoYeah, sorry, brainfart. I have only ever used NVMe drives in M.2 so I completely spaced that you can put 'em in PCIe slots too (which is probably more popular, actually?). Thinking about it, that (2 x NVMe in PCIe) will probably be the first upgrade I do to my new workstation in the future. It looks like those only use four lanes each and I've got enough still available (80 total) to support way more of these drives than I expect to ever need on my desk. ETA: PCIe v3.0 x16 == 15.75 GB/s. I expect we'll see, at some point, PCIe cards/adapters that support up to 4 NVMe drives (in one slot). Hell, they might exist already.
