Juniper has open sourced its SDN controller for its Contrail Software Defined Networking offering and started http://opencontrail.org to host the Apache 2.0 licensed software. the source is available on GitHub.
At the time of the order, we had a grand total of 112 servers so 1680 was a huge step. But by the summer, these racks were running search for millions of users. In retrospect the design of the racks wasn't optimized for reliability and serviceability, but given that we only had two weeks to design them, and not much money to spend, things worked out fine.
BTW the four white pins in the forefront are the reset buttons for the four servers, and the disks are mounted on a plexiglass board which lies on top of the board (not attached -- there was no time to design a proper bracket).
