Webfusion Leeds Datacentre
Webfusion owns a datacentre in Leeds. The site uses a fast, resilient network thus giving a very fast connection speed to the Internet. The datacentre is in a purpose built building that offers a high level of redundancy to keep the systems alive. The datacentre is manned 24 hours a day by experienced engineers.
Fire Prevention
The Fire prevention system is constructed of strategically placed detectors (smoke and heat) creating ‘zones’ within the floor and ceiling voids. The system works on a ‘double knock’ basis, comprising ionization and smoke detectors. The system is linked/interfaced into the House Building System. Fire suppression is provided by a gassed based Inergen Fire prevention unit.
Power
The supply is distributed from the YEDL Board’s 11KV ring main. The UPS is a battery inverter floating 1200KVA with an instantaneous electronic change over switch providing over 20 minutes of power while generators kick-in. Generators start within 10s of a power failure. The generator is a dedicated 1250 kva unit, with at least 48 hours worth of fuel held on-site and at off-site reserves. In addition to on-site stores, in the event of an emergency, tanks are refueled two separate fuel suppliers.
Air Conditioning
Climate control systems monitor and adjust temperature and moisture levels, suites use tight controlled gas based air conditioners each of which is of a dual circuit design with two chillers, compressors and condensers providing two independent circuits for maximum availability. There is ample ‘redundancy’ in the calculation should a unit fail, within the current configuration of seven 40Kw Airedale down flow units. Each unit delivers 30t/r cooling. Each unit is redundant, having two separate cooling circuits. Aircon units are N+1 redundant. The air conditioning is set to 24C and 50% relative humidity. Air conditioning is monitored 24*7, and automatically dials out for repair in the event of component failure.
Security
Access is via card-based security system. Fire-exits alarmed and monitored by CCTV.
Floor
The floor is raised with under floor moisture detection. The floor is rated at 1000kgs per sq meter.
Power Supply Rack
Each rack has two power feeds each fused with a 32Amp PDU which runs ‘commando style’ sockets these come from separate distribution boxes which are fed separately through the building from the UPS system, via armoured cabling. Three-phase and 32Amp power can be installed to customer racks.
Datacentre LAN
The LAN is based on Cisco architecture with no single point of failure throughout.
Connection
THe network has direct access to LINX as well as several other major internet exchanges.
