The Grubb & Ellis Data Center Group has quantified the supply/demand metrics for key U.S. data center markets in its year-end reports.

The findings indicate that in 2011, there are markets that will be underserved and there are markets with not enough demand or too much potential supply. The problem or opportunity depends on whether you are a tenant or a landlord, the report states. In Atlanta, there is potential for a huge demand/supply imbalance particularly if Google vacates the 20 MW of wholesale leases in favor of their owned property. Santa Clara could be challenged if some of the proposed properties are delivered and New Jersey is challenged by limited demand. Downtown Chicago looks to be the tightest market during the foreseeable future and Virginia may have supply constraints.
