Another returning winner is American Power Conversion's (APC's) APC Symmetra RackMount Power Array, which for the second year won Best Uninterruptible Power System with 81 percent of the vote—even more than last year. Our readers couldn't praise this product enough, and many said they simply wouldn't use anything else. Reader Steve Cummings seemed to speak for most voters: "Gotta love APC."

As an addition to APC's InfraStruXure integrated rack, power, and cooling architecture, Symmetra offers an open and adaptable solution for server rooms, wiring closets, and other small to midsized computing environments. Symmetra is one unit made up of modular components. This modular architecture provides the foundation for building and scaling near-continuous- availability power systems with a flexible range of power capacity. Combined with APC's data center—protection software and accessories, Symmetra provides redundancy, scalability, manageability, and serviceability.
