An anonymous reader writes "Oracle is exploring silicon photonics, an optical technology drawing widespread interest, as a potential weapon in the battle against data-center power consumption. Advances in CPU and memory design could boost efficiency dramatically over the next few years. When they do, the interconnects among components, servers and switches will effectively become the power hogs of the data center, according to Ashok Krishnamoorthy, architect and chief technologist in photonics at Oracle. Oracle isn't often associated with networking and may not even manufacture or sell the technologies it's now studying. But as a big player in computing and storage, it could benefit from fostering a future technology that helps make faster, more efficient data centers possible."
