The Open Compute Project storage page also references Fusion-IO PCIe storage cards with up to 3.2 TB of storagecapacity, which are used by Facebook to speed up overall storagesystem performance.
Using DDN's SFA12K-40 storage systems as the backbone for Spider II, this new file storagesystem is designed with 40 petabytes of raw capacity and is capable of ingesting, storing, processing and distributing research data at unprecedented speed.
With the right combination of capacity, performance and rapid power cycling storagesystem designs can pump more iron while keeping cool and saving energy.
