Facebook Open Compute: A New Database Server Design

Facebook has released under the Open Compute umbrella the design of a new database server they’ve introduced in one of the datacenters. The bit that caught my eyes is that this is not about more disk space or more CPU, but redundant power supplies:

According to Frankovsky, for certain database functions at Facebook, it was more important to have redundant power supplies for a database node than it was to have multiple compute nodes in an Open Compute V2 chassis sharing a single power supply. […] Frankovsky said that by doubling up the power supplies and making an Open Compute-style database server, it was able to cut the costs over its current database servers by 40 per cent.

The spec can be found ‎here (PDF).
