• Fully resilient, high-density dual power (11KV) supplies featuring independent tripping, automatic failover to UPS and generator backup, together with diverse routing into the building.
• Power resilience and diverse routing includes switchgear, UPS and power distribution units dedicated to each supply, and a total of 6200kVA generator capability. The latter can support a single supply or both incoming supplies and run for 48 hours without refuelling. The generators are tested on a weekly basis.
• State of the art Vesda (Very Early Smoke Detection Apparatus) and FM200 fire suppression systems capable of running in manual or automatic modes protect each machine room, with the entire site covered by conventional smoke detection sub-floor, at ceiling height and in the ceiling void.
• Goods received are unpacked in designated areas adjacent to the loading bays. Flammable packaging materials are not taken into the machine rooms or stored, but are removed from site as soon as possible and disposed of.
• Two separate Energy Centres are utilised for enhanced resilience and reduced risk of impact on system operations due to infrastructure problems. One is linked to the main data centre building by a canopy enclosing mechanical and electrical equipment / supplies; the other is a new facility added in 2007 to increase the power density of the site.
• The site is fully air conditioned, with N+1 capacity to each machine room providing the ability to support the latest technology including blade centres. Chilled water is generated in the Energy Centre by five Hitachi water cooled chillers each with a cooling capacity of 225kW.
• Heat rejection from the chiller units is via evaporative coolers located on the roof of the Energy Centre. Five coolers are currently installed, each with a capacity of 288kW.
• A total of 21 Air Handling Units (AHU’s) is distributed across the two air handling corridors with various ratings from 16.5kW to 100kW.
• These are supplemented by a total of 22 DX type air conditioning systems each with a cooling capacity of between 70kW and 90kW.
• A minimum of "N+1" resilience designed in all critical environmental services. In some areas Getronics has 100% redundancy. The environmental services and conditions are monitored and controlled by a Trend Building Management System (BMS). Outstations are located within dedicated panels around the building with a central supervisor console. Alarms are received in the Central Security Office.
