Kerrigan, said that 32 percent of space leased data center is up for renewal by 2013, while placing and wholesale price data center are up to 15 percent.

There is a stronger demand for smaller operations, particularly for plants with a capacity of 300 to 800 kW. The data center operators are increasingly using modular designs, with POD sizes of 9,000 to 10,000 square meters.
