According to the engineering team, this full-stack approach toward establishing efficiency while reducing operating power is based on building racks with double petabyte (or two million gigabyte) storage systems that operate at a quarter of the power typically used by conventional storage servers.

The engineering team acknowledged that they are "lucky" to have both the financial and technological support (not to mention encouragement) to build such hardware and software from scratch and experiment with them.
"Too often, we've all seen systems begin to get bogged down as they grow and become more utilized,"Patiejunas and Bandaru wrote. "So, right from the beginning, we vowed to make a system that not only didn't degrade with size but would get better as it grew."
Facebook has already established two cold storage facilities in the last year at its data centers in Prineville, Oregon and Forest City, North Carolina, together hosting "hundreds of petabytes" of data -- an amount Patiejunas and Bandaru admitted is ballooning daily.
