I think AMD Epyc is a perfect match for this... 128 PCIe lanes per socket.
On a dual socket Epyc system with 36 of these, each with a 4x PCIe connection 'only' takes up 144 lanes, leaving plenty of lanes free for even 8x Dual-QSFP+ 40GbE NICs.
Of course, I'm not sure how you'd physically pack all of that into even a 2U form factor.
Usefulness... data warehouses. If the price was right, we'd probably move to that to speed up various ingestion & reporting functionality. At 288TB (assuming RAID10) capacity, it'd be a perfect fit.
- Dylan16807 8y agoEpyc is 128 lanes period. The dual-socket configuration steals half the lanes for the interconnect. It's also PCIe 3 for now.
- paranoidrobot 8y agoAh, right. My mistake. Still, I think it might be in a better position than Xeon for raw storage IO.
- scurvy 8y agoixnay on the 40gig-ay 25/50/100 is cheaper/better on modern gear.
- paranoidrobot 8y agoFair enough, I wasn't aware of 100G adapters.
- shaklee3 8y agoUnfortunately it's not pci 4, though.
- paranoidrobot 8y agoIt looks like these are PCI3 SSDs, and with a bit of poking around I can't see any PCI4 Xeons out yet either.
- shaklee3 8y agoI was going by the title, which said it's PCIe 4.
- jburgess777 8y agoThere has been an update to the article: Update 6/22: Samsung made an update to its statements regarding the NF1 SSDs. The drives are based on the Phoenix controller, they do not use a PCIe 4.0 interface, but rely on a more traditional PCIe Gen 3 x4 interface.
- shaklee3 8y agoAh, thanks for catching that!
