RAID adapter cards are critical data-center subsystem components that ensure data storage and recovery during power outages. Current battery-backed designs create green issues around hazardous waste disposal as well as shelf life and maintenance issues. Recent advances in FPGA and flash-memory technologies support lower power memory backup designs that are powered by batteries or “green” ultra capacitors. This white paper provides an overview of the supporting component technologies that can support such an environmentally-friendly data recovery solution.
