When Janna Bridges, Volusia County Schools data operations manager, first stepped into the district’s data center in Deland, FL, in 1998, she entered a room that contained one mainframe, two high-speed laser printers, two 15-ton computer room air conditioning (CRAC) units (N + 1 redundancy) and a single 50 kilovolt-ampere (kVA) three-phase, 480-Volt uninterruptable power supply (UPS).
Fifteen years later, Bridges oversees a 1,435-sq-ft data center located in the district’s DeLand Administrative Complex that includes 38 cabinets holding more than 200 servers (and 300 virtual servers), three 15-ton CRAC units, and two 225 kVA three-phase 480-volt UPSs. At the heart of the system is a 10 gig fiber ring, with 1 gig to each site.
