For Chicago-area companies that need big-time computing power and resources but can\u2019t afford millions for their own offsite data centers, new help is on the way.This spring, the Cyber Continuity Center, a high-density colocation data center 35 miles west of the Windy City, will open, serving midsize (Fortune 100 to 500) companies, says Bob Lacy, executive vice president. Customers will pay a per-rack fee for server space, monitoring and related services.Additional fees cover \u00bfa carte services such as incident tracking and data recovery.The 62,000-square-foot building is windowless, made of reinforced concrete and far enough from Chicago\u2019s business epicenter that it won\u2019t be affected by interruptions to city power grids. It exceeds the Uptime Institute\u2019s Tier III Data Center designation. As you\u2019d expect, energy efficiency poses major concerns: The center is built around American Power Conversion\u2019s InfraStruXure architecture for high-density blade server deployments. (InfraStruXure integrates power, cooling, security and related services.) The center\u2019s APC racks are cooled by large chillers that circulate cold water via pipes.Mid-market CIOs can expect more colocation centers like this in the future, says Jed Scaramella, a research analyst at IDC (a sister company to CIO\u2019s publisher).
