Domich said that the need for stronger defenses has helped commercial data center providers, which have typically put a lot of focus on security.
One such firm is Vantage Data Centers in Santa Clara, Calif., which leases out data center space in a complex located on an 18-acre campus. Its facility is approximately 310,000 square feet.
Vantage CEO Jim Trout says the facility is surrounded by an eight foot-tall fence capable of stopping a car. Beginning with the gate, there are as many as seven points in the facility where visitors are checked. There are guards, biometric fingerprint identification systems, mantraps and cameras that all serve to limit access to the facility and keep track of visitors.
The facility also has redundant systems, including redundant electrical capacity, so if one system gets knocked out there's a backup to take its place, said Trout.
"There is no question," said Trout, that 9/11 affected the way data centers are secured.
