The lights are even powered by Power-Over-Ethernet. Slick. Anyone know who supplies these?

From http://opencompute.org/specs/Open_Compute_Project_Data_Center_v1.0.pdf :

4.11 LED Lighting Systems
Energy-efficient LED lighting is used throughout the data center interior.
        Innovative power over Ethernet LED lighting system.
        Each fixture has an occupancy sensor with local manual override.
        Programmable alerts via flashing LEDs.

It seems to me that the natural evolution in hard drives would be to build the flash cache on to the controller board on the hard drive. Is any drive manufacturer building this kind of hybrid flash/magnetic drive?
