Complete 360° CCTV coverage with auto tour and PIR activation. External CCTV tours the perimeter of the building, and should anyone approach any predetermined point (gates, doors, points of entry) the CCTV will quit its tour and focus on the point of trigger. The CCTV system also covers all internal points of entry. Footage is automatically backed up, both locally and off site, and is remotely accessible by data centre staff.
The perimeter alarm system, with beam detectors covers roof access, all doors, roller shutters and windows.
Entrance to the compound itself is via remotely operated gates for which only staff have access. Entrance to the site is only granted via data centre staff after the visitors identity has been verified via CCTV. A door entry system inside the building which requires swipe card access to gain entry to parts of the building.
Additionally the datacenter is manned 24/7 365 days of the year by at least 2 members of (UK2) staff. The building is completely plain, with no external signs of what is inside the building.
The datacenter has its own substation which is inside the secure inner compound. The substation is on its own 11KV feed from EDF and runs its dual transformers. The transformers are over-specified for their current usage.
The transformers feed automated switchgear which distributes the power around the datacenter. It has auto failover and in the event that main power fails, it sends signals to the Generator Sets which fire up automatically and switch over. The switchgear has its own independent charge unit which in the event of power failure has enough capacity to fire the relays to switch to generator power. There is a shunt switch in the mid of the panel, which allows one half of the panel to feed the other in the event of single gen or transformer failure.
The generators are maintained on a regular basis and are run up for between 2 and 4 hours a month. The fuel supply is onsite and houses enough fuel to run the generator at full load for 10 days. Contracts are in place to top the diesel up within 4 hours where necessary.
All of our racks are backed up by their own individual UPS units. These units are fast enough to offer unnoticeable transfer between the mains supply and the generator supply. In the event of the generators failing or needing major works, a 2nd generator can be added to either power system quickly.
