Hi Owen, Hot-aisle/cold-aisle is a separate issue from a raised floor plenum. They're mutually supportive but not mutually dependent. Raised floor has pros and cons which make it good or bad depending on the environment. If you haven't yet started implementing hot aisle/cold aisle, on the other hand, you're already the better part of a decade out of date and your equipment is suffering for it. For the original question: Non-plenum short raised floor can be useful if you want to separate your power and data wiring. Other than that, I can't see any advantage versus a solid floor and either snake tray or other overhead wiring systems. Regards, Bill Herrin -- William D.
