TL;DR - FB historically has always used a dual-socket setting up. They started noticing the trend in Intel chips to be only getting marginally faster yet using vastly more power. They needed to change this curve. So 3 years ago they starting working directly with Intel. The result was the Xeon-D chip. FB current setup is a single socket Xeon-D which is faster than the old dual socket setup and uses 1/2 the power.
- askafriend 11y agoThank you for your service! I would pay for a TLDRAAS.
- wocram 11y agohttp://smmry.com/ http://smmry.com/ produces: We have been using traditional two-socket servers for more than five server generations now at Facebook. Because our web servers are heavily compute-bound and don't require much memory capacity, the two-socket servers we had in production had several limitations. Mono Lake is the server embodiment of Xeon-D and the building block for our SOC-based server designs.

- MzHN 11y agoThis should be a HN feature. Ability to submit TL;DRs to a post in a way similar to commenting. An option to always show the top voted TL;DR, and a link to dive in to other interpretations. A wiki-style service for TL;DRs could work too.
- lqdc13 11y agoI guess it is very much workload dependent. New E5-2650L is 2x faster on many workloads, which is the EP line they're comparing it to. Not sure about power.
- ntucker 11y agoAlso of interest is the fact that they settled on using a multi-host NIC to share a single NIC between four single-CPU servers.
- acqq 11y ago> uses 1/2 the power. Actually the power use is the same per rack, it's just faster compared to the previous performance per rack, for their workloads, compared to what they'd get by keeping dual socket with this CPU generation.
