Webfusion Leeds Datacentre
Webfusion runs its own 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. It is manned 24 hours a day by experienced engineers.
Fire Prevention
The Fire prevention system utilises a VESDA smoke detection system monitoring ‘zones’ within the floor and ceiling voids. The system works on a ‘double knock’ basis. The system is linked into the House Building System which is monitored by the fire emergency services. Fire suppression is provided by a gassed based Inergen Fire prevention unit.
Power
The supply is distributed from the YEDL Board’s 11KV / 2MVA ring main. The parallel UPS cluster ensures power is maintained during the automatic electronic change over should the mains fail and the stand-by generators kick-in. Generators start within 10s of a power failure. The generator is a dedicated 2 MVA unit, with at least 48 hours worth of fuel held on-site. In addition to on-site stores, we have a contract with a fuel provider ensuring our tanks are always full.
Air Conditioning
Climate control systems monitor and adjust temperature, suites use tight controlled Direct-Expansion based air conditioners each of which is of a dual circuit design with two independent circuits of compressors and condensers providing maximum availability. There is ample ‘redundancy’ in the calculation should a unit ever fail, within the current configuration of seven 90Kw Airedale down flow units. The air conditioning maintains an input temperature to the hosted servers at 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 the server racks.
Datacentre LAN
The 10Gb/s network 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.
