We are the integration partner for Facebook, at least in Europe, and one of our divisions helped them work through some design challenges re: heat dissipation, PDU routing, and HDD density. We are NOT the EMS who manufacturers the servers for them, and the well-known company they're using is providing crap quality. We see about 10% failure (to the point of having to scrap the server) rate after we rack and start burn in and system test.
Honestly speaking, one of the things that interested me the most was the fact that FB is running a custom Linux kernel ... and they update it way more frequently than our test engineers are happy about. I'm happy to answer non-NDA questions.
- alricb 12y agoDo they use 277 V AC in Europe? Or do they stick with 240 V?
- eitally 12y ago240V
- monksy 12y agoI'm not sure if you're able to answer this or not. Is it a FB specific configuration? Or are they writing their own drivers/cpu-scheduling?
- eitally 12y agoThe latter. It's extremely irritating because they expect us to write the system tests for everything from the HDDs to RAM to Fusion I/O cards to network interfaces, and all we have to start from are the standard stuff ... so when they change things and don't provide tests, it is unpleasant.
