Power Distribution & Management

ServerVault has one of the most capable and dense power infrastructures in the hosting/Data Center industry. ServerVault’s power infrastructure is highly redundant with N+N components for all key functions, ensuring complete redundancy and availability for all devices that are hosted within its facility. Since its inception, ServerVault has not experienced a power outage of any kind within our facility.

ServerVault is powered by a 2,000-kilowatt feed, coming from the public utility company and terminating on our site. Utility power is backed up by an industry-leading Caterpillar diesel generator plant, which provides two megawatts of backup power generation. The generator, in the event of a utility power failure, powers 100% of all building systems. The system is protected from spikes and over-voltage conditions with a Transient Voltage Surge Suppression system (TVSS). Multiple UPS systems provide transient power so support critical loads. These systems feed downstream power distribution units (PDUs) in each vault, which in turn feed individual circuits.

All of these power elements are connected in a hub topology, which eliminates any single line of dependencies all the way down to the individual power outlet. The system foundation is based on the latest General Electric switchgear, and has 82 discrete points of automatic measurement. Automated systems revert to our own power generation facility if any of the measured attributes are out of allowed tolerances (phase shift, under voltage, etc).

UPS, PDUs, and Backup Power

The data center provides 265 watts per sq. ft. of UPS power, which is approximately 4.6 kilowatts per rack. The UPS system has N+N redundancy. Each dual inverter UPS is powered with a battery system capable of supplying eight minutes of power after an interruption, if fully loaded (16 minutes total run-time). Our UPS system consists of multiple 800 KVA UPS manufactured by MGE. These are double conversion UPS systems, which provide instantaneous fail over to UPS upon any interruption of normal AC power.

The double conversion system also isolates the downstream load from the upstream transformer or generator, eliminating transmission of any upstream fluctuations such as spikes or over voltages to the load. Power is fed to each rack through separate PDUs, which are dual-fed, static transfer switch PDUs. In the event of a utility power loss, power is supplied to the UPS system from the Caterpillar power generation plant. Power generation starts automatically after a utility power failure and comes online to support the entire building load within nine seconds. This keeps the UPS discharge time well below its 16-minute capacity.

The Caterpillar plant has sufficient diesel fuel to operate at full load for 24 hours without refueling. Time-guaranteed contracts with multiple diesel fuel suppliers guarantee that ServerVault can operate indefinitely in the event of a prolonged public utility outage.
