What is the GRC ICEraQ Series 10?
ICEraQ Series 10 is a modular, single-phase immersion system for dense compute. Adapted servers sit vertically in dielectric fluid, which stays liquid while pumps carry component heat to a plate heat exchanger and facility-water loop. Server fans are removed or disabled, but power distribution, networking, lifting, draining, and dry space for unsupported devices remain part of the design. GRC published configurations with two or four 42-rack-unit tanks per coolant distribution unit (CDU). It rates the Series 10 CDU at 200 kW with warm water and up to 368 kW with chilled water. Those are different duty conditions, so a buyer should not compare the larger figure with a warm-water product. GRC supplied Series 10 equipment for the Texas Advanced Computing Center's Lonestar6 supercomputer, a useful operating reference but not proof that every commercial server can be immersed. Check every board, cable, label, connector, drive, power supply, and warranty against the selected fluid. Ask for inlet-water requirements, flow, pressure loss, electrical use, fluid volume, floor load, spill containment, fire review, and capacity with one pump or controller unavailable. Operations teams should witness the actual lift, drain, repair, and refill process and define how long a wet server may remain out of the bath. The cited deployment source does not disclose project-level efficiency, availability, maintenance hours, or fluid life, so those claims need site references and contract terms rather than inference.
