Facebook's "Open Compute" Server tested
by Johan De Gelas on November 3, 2011 12:00 AM ESTConclusion
The HP DL380 G7 continues to earn our respect as a very effcient server. It is also a much easier server to handle, thanks to its integrated graphics chip and remote management (BMC). Still, it is clear that these features are not that important for web applications that have to scale out over a large number of servers.
Each rack at Facebook contains 30 Open Compute servers
The Facebook Open Compute servers have made quite an impression on us. Remember, this is Facebook's first attempt to build a cloud server! This server uses very little power when running at low load (see our idle numbers) and offers slightly better performance while consuming less energy than one of the best general purpose servers on the market. The power supply power factor is also top notch, resulting in even more savings (e.g. power factoring correction) in the data center.
While it's possible to look at the Open Compute servers as a "Cloud only" solution, we imagine anyone with quite a few load-balanced web servers will be interested in the hardware. So far only Cloud / hyperscale data center oriented players like Rackspace have picked up the Open Compute idea, but a lot of other people could benefit from buying these kind of "keep it simple" servers in smaller quantities.
Looking back over the past few years, a significant part of the innovation in IT has been the result of people building upon or being inspired by open source software (think Android, Amazon's EC2, iOS, Hyper-V...). We look forward to meeting the new data center and hardware technologies that the Open Compute Project will inspire.

I'm not sure how much of the benchmarks depend on network bandwidth, but Facebook certainly does a lot of it. Using SRIOV based NICs and supporting drivers allows the VM to access virtual NIC hardware directly, without having to go through the hypervisor. But, all NICs aren't built equal, many of them do not support SRIOV, and those that do, may not have drivers which support it in older kernels such as Centos 5.6. Unfortunately, since most Gigabit NICs were designed before SRIOV, most gigabit NICs don't support it. We have great difficulty getting hardware vendors to describe whether the provide SRIOV capable hardware or Linux drivers. The newer 10G NICs tend to support SRIOV, but whether the server needs more than 1G is unclear, and the 10G NICs are more expensive and use more power.CPU-Hog - Sunday, November 6, 2011 - link
Good comparison of the servers however I couldn't help but think how much better it would be if we ran actual workloads that facebook etc plan to run in the datacenter vs. these enterprise workloads. How about running MemcacheD / Hadoop / HipHop etc. which are the key workloads the OpenCompute servers are designed to run well.Many of these workloads need large IO and memory vs. high compute. It will also be interesting to then use the same benchmarks to compare future servers based on technology from newbies like Calxeda, SeaMicro and AppliedMicro.
Xeon and Opterons based servers vs. ARM and Atom based servers. Now that battle of the old guard vs, the upstarts will be worth seeing.

Johan,Thank you for excellent article. I love to read about cutting edge technology. Keep with the good work. But, I notice something that nobody in the comments has mention yet. In the last paragraph:
"... being inspired by open source software (think ..., ..., iOS, ...)."
iOS is a Open Source Software?! When this happen?

Since these systems are custom designed by Facebook engineers, I'm guessing you can't purchase anything like it, correct? Will that change with that foundation that Open Compute announced recently?artemisgoldfish - Thursday, November 10, 2011 - link
Getting Power One to design a supply just right requires a LOT of testing. It's also strange to me that the supply only takes 200-277VAC. The Power One AC supplies I'm familiar with do 90VAC to 264VAC and pass 80PLUS Gold, maybe the tighter input range helps them tune it for more efficiency.ahmetmy330 - Friday, December 30, 2016 - link
