Physical security is particularly important for Internet datacenters. The closed building provides restricted access to authorized personnel only. All facilities are guarded on a 24-hour basis and video surveillance covers all "critical" areas, including entrances.

The FreeBSD UNIX servers are extensively tested and coordinated for maximum performance. All non-necessary services are disabled, all security patches are up-to-date and servers are audited regularly for attempted break-ins.

The heat output of hundreds of powerful computers on the network requires redundant and uninterruptible climate control. Pair's system, Liebert 30-ton, ensures the well functioning of all systems.

Providing continuous clean power is a significant challenge for modern datacenters. All power is delivered through the massive Powerware 9315 Hot Synk online Uninterruptible Power System. Weighing in at more than nine metric tons, this unit can operate the entire facility.

The UPS is prepared but rarely needs to provide power from battery, as the Automatic Transfer Switch ensures that a standby generator comes online promptly in the event of an outage.

The factory-new 750.000-watt Caterpillar diesel generator provides emergency power for the facility, in the event of utility outages. Started by Automatic Transfer Switch this generator can power the datacenter indefinitely.

FIRE SUPPRESSION SYSTEM

The automatic fire suppression system uses distributed sensors to determine when there is danger of fire or smoke conditions and it is programmed for automatic fire suppression in case of emergency.

It is equally important that the fire suppression system is designed to smother fires without damaging electronic equipment.

FREEBSD UNIX SERVERS

Pair Networks maintains more than seven hundred FreeBSD Unix servers in their datacenter. The facility is capable of hosting nearly three thousand (3.000) such servers (using only top-of-the-line Intel and AMD processors, tuned specifically for reliability and high performance).

Security copies of all data are maintained on a 24-hour basis (backup) and there are numerous spare servers, which are able to upgrade or replace servers easily at any time.
