'Jupiter rising: A decade of Clos topologies and centralized control in Google’s datacenter networks'
Love the 'decade of' dig at FB and Amazon -- 'we were doing it first' ;)

Great details on how Google have built out and improved their DC networking. Includes a hint that they now use DCTCP (datacenter-optimized TCP congestion control) on their internal hosts....

Facebook introduce “Wedge” and “FBOSS"
a new top-of-rack network switch, code-named “Wedge,” and a new Linux-based operating system for that switch, code-named “FBOSS.” These projects break down the hardware and software components of the network stack even further, to provide a new level of visibility, automation, and control in the operation of the network. By combining the hardware and software modules together in new ways, “Wedge” and “FBOSS” depart from current networking design paradigms to leverage our experience in operating hundreds of thousands of servers in our data centers. In other words, our goal with these projects was to make our network look, feel, and operate more like the OCP servers we've already deployed, both in terms of hardware and software.


Sayonara, Cisco, and good riddance.

A Tour Inside CloudFlare's Latest Generation Servers
great transparency from CloudFront! Looking at their current 4th-gen rackmount server buildout -- now with HP after Dell and ZT. Shitloads of SSDs for lower power and greater predictability in failure rates. 128GB RAM. consistent hashing to address stores instead of RAID. Sandybridge chipset. Solarflare SFC9020 10Gbps network cards. This is really impressive openness for a high-scale custom datacenter server platform...
