This distributed redundant configuration is significantly superior in terms of reliability and load availability to all conventional facilities based on the traditional N+1 architecture.
The critical infrastructure architecture is designed to eliminate all single points of failure and to enable concurrent system maintenance. The basis of the state-of-the-art, fault tolerant system is a dual feed, dual path topology, using multiple independent Uninterruptible Power Supply(UPS) systems, Generators, Air Conditioning Units, Automatic Static Transfer Switches (ASTS’s) and Power Distribution Units (PDU’s).
The basic system architecture consists of two primary electrical buses. Each bus is fed through an ATO by a dedicated transformer and a standby generator. Each primary bus feeds up to five stand-alone static 750 KV modules and multiple air-cooled, packaged air conditioning units.
The load distribution to the rack mounted equipment is done via Dual Independent Parallel power feeds to each Remote Distribution Unit (RDU). Essentially, the entire power distribution system has redundant paths from the utility main service all the way through to the last power distribution point in the computer room, which is the RDU. The PDU’s have dual transformers providing complete independent power feeds.
To achieve this level of reliability the following measures were implemented.
Utility Service
Two fully redundant electrical supply services derived from different utility primary feeders off different transformers serve the data centers.
Main Electrical Distribution System
The facility is equipped with two main electrical distribution buses. Each bus is supported by the utility supply and by an independent generator system. Any one bus is redundant.
Parallel Transformer Power Distribution Unites
Parallel Transformer Power Distribution Units have primary feed from each of the primary distribution buses at 250 kVA.
UPS Systems
A total of Five (5) 750 kVA, 675 kW UPS modules are installed. Two 750 kVA, 675 kW primary UPS modules are installed on each of the two (A & B) primary main buses. Each UPS module is equipped with batteries that with a fully occupied data center provide at least 10 minutes of power, an internal static bypass and an external maintenance bypass.
A back-up UPS consist of a 750 kVA, 675 kW module connected in a switched mode to each primary UPS sub-feed. This system provides the alternate UPS source to the Parallel Transformer PDU’s. This system is also equipped with dedicated batteries, internal static bypass switch and external maintenance bypass. The condition of the batteries is continuously observed using a state-of-the-art battery monitoring system.
Standby Generator Systems
Two (2) 2500 kVA Generator. Each generator is equipped with a self-contained integral diesel fuel tank sized to support the full load for 24 hours. A third 2000 kW diesel generator set can be added that will activate if either primary generator set fails.
Grounding System
Comprehensive grounding system, including a Zero Signal Reference Grid (ZSRG), and full building loop ground. A lightning protection system that has been designed to minimize the effect of a direct lightning strike and primary bus switching system is protected by TVSS (Transition Voltage Suppression System) in the event of abnormal power surges.
