Szuperbiztonsagos datacenter: NY4

The 49 different exchanges that lease space at this data center sent a record 9.6 million messages per second through its fiber-optic cables in February. Every day, electronic trades representing trillions of dollars’ worth of equities, derivatives, currencies, and fixed-income assets pass under this roof. This is NY4. This is where Wall Street actually transacts.

The security at NY4 bears this out. To get from the parking lot to a spot where you could touch one of the servers you’d have to go through five checkpoints. One of them is a so-called man trap with two automatic steel doors that never open at the same time. Your palm print is required twice in addition to your PIN code.

They’re big on backups. In case of a power failure, NY4’s uninterrupted power supply room has 5,600 batteries on standby to provide eight minutes of electricity while the generators rev to life. Should the air conditioning fail and risk the servers overheating, there are three 150,000-gallon tanks filled with water chilled to 45F. Running that cold water through pipes would give NY4 staff 20 minutes to get the AC fixed. Oh, and the generators: 18 of them, each the size of a locomotive engine and able to crank out 2.5 megawatts of power. Equinix keeps 180,000 gallons of diesel fuel on-site to run them.
