Here's an example of how growing demand for medical records management is boosting demand for data centers. Medical billing specialist Emdeon (EM) said this week that it has leased a 34,200 square foot property near the Nashville airport for a new data center. The company signed a 15-year lease with Solomon Airpark LLC for a shell building at Airpark Center East, which will be converted into a data center to replace Emdeon's existing Nashville data center located at One Century Place. Emdeon will pay initial rent of $39,500 per month, and will have the option to extend the lease agreement through two five-year renewal terms. The lease agreement is described in an SEC filing.
