SearchDataCenter: Live data center modernization: A nail-biting experience
Todd Gale likened his company's recent data center modernization to picking up a running locomotive off one track and placing it on another without disruption.
The task was to upgrade a 25-year-old data center, built by AT&T during the 1980s to handle mainframe computing. The building was 125,000 square feet; the data center space, 80,000 square feet. In this case, modernization required ripping and replacing most of the facility's power and cooling infrastructure -- all without incurring system downtime.
Gale, the regional data center director for the Denver-based colocation company ViaWest, led the charge, and the process took 18 months.
