Telehouse, London Docklands Facility

Home to the Telehouse EMEA Headquarters, London Docklands is the main base for Telehouse's UK facilities with Telehouse East, North and the newly launched flagship facility Telehouse West based on campus.

Since becoming the site for London's first, carrier-neutral data centre and home to the London Internet Exchange (LINX), the London Docklands have fast developed to become the UK's foremost internet hub, thanks to Telehouse's pioneering data centre campus construction in the area, providing a vital network of connectivity and data exchange, as well as a backbone for the global internet network.

Building Type
The building is a multi-story steel and concrete construction, purpose built as a data centre. Ceilings, walls, floors and doors comply at least with RF90 (fire resistance 90 minutes) in data centre areas, telecom rooms, and plant areas.

Internal Design Details
The floor space is divided into Facility Management Suites of various sizes and consists of physically separate areas for shared and dedicated facilities with their own access controls.

Site Security
The facility is physically guarded 24/7. Visitors are required to sign in at the gatehouse and again at the main reception building.
Proximity card access is then provided to the main Data Centre building and to specific Facilities Management Suites. There is an alarm system that will respond to doors left open, or to attempted unauthorised access. A record is kept of door openings and all proximity card transactions.

There is a CCTV coverage for the perimeter, common areas and facilities management suites.
The Data Centre site is protected by a perimeter fence, which is fitted with intruder sensing.

Cooling Facilities
In-room data centre air conditioning is provided at N+1 redundant unit capacity for the declared load. The heat rejection system is 30% glycol and condensed water which utilises dry heat rejection condensers on the rooftop.

The in-room units provide a full function, closed control air conditioning system, with cooling, humidity and de-humidification control.

Room design temperature: 22 degrees C, plus or minus 1 degree C. Room humidity: 50% rH. Plus 10% or minus 10% rH.

External Temperature Design: 35 degree C Dry Bulb.

There is a redundant "A" & "B" pipe work route to the roof top condenser system and N+1 pump system in the North Building to circulate the glycol condensed water to the data centre in-room air package equipment. The East Building works on "A" or "B" pipe work to room with N+N redundant units and N+N pumps.

Electrical Power Supply
6 independent 11kv three phase electrical supplies are provided from 3 separate national grid substations. Standby Generation is provided at N+1 redundancy via diesel engine driven generators.

On-site fuel is stored to maintain full load operation for all generator sets for continuous running of 24 hours. Back up deliveries are available from diverse supply depots.

Uninterruptible Power Supply System (UPS) is available to provide N+1 redundancy for critical computer supplies. The UPS can support the facility for 15 minutes at full load, whilst switching to alternate supply, or standby generation start-up/synchronisation takes place.

Fire Detection/Suppression
The data centre area is fitted with a fully addressable 2 stage fire detection system that monitors the under floor, room and ceiling void space. The detectors are a 50% mix of optical and ionisation and are installed split across 2 separate zonal-loops, to meet BS 5839, 6266, 5445, 5588. The data centre area is fitted with a dry sprinkler fire detection system to meet BS 5306, 3115 and has LFEDA approval. Whilst dry sprinkler is the main fire suppression method used, gas suppression areas may be available on request.
