Host Color Europe data center's redundant power feeds

The facility has a scalable power infrastructure with the highest level of reliability. It offers a minimum of N+1 redundancy for every power system element and delivers the highest possible power quality and uptime. The data center operates four independent power feeds @10kVA from two separate 110 kVA grid sub-stations and has two redundant power transformation units. An Automatic Transfer Switch (ATS) system, produced by Siemens, reconfigures low voltage power sourcing, upon outages or excessive high urgencies fed into the UPS groups. Manual electrical power source selection system @ 10kV is in place, in case of need to switchover different power feeds

Backup Power (Diesel Generators)

Host Color Europe data center's redundant power feeds

A Backup group of synchronized diesel generators in N+1 grade of redundancy provides power backup. All IT components are also grounded for both equipment and occupant’s safety. The Main Power Distribution Units (A&B) and the floor PDUs (A&B) are based on ABB. All power cable paths and systems are fully A+B redundant, using separate cable trays, routes, with all PDU’s, ATS and equipment separated physically in different rooms.

AEG’s SVS series UPS system provide the two separate groups each with N+1 redundancy. Each UPS unit has it's own dedicated battery string with Exide’s batteries sized for 20 min backup time at full load.

Cooling Equipment

  • Redundant N+1 100 kW CyberAir2 systems CRAC units by Stulz
  • Redundant 1+1 circulation pumps with variable frequency drive motors by Grundfoss
  • Redundant Guentner dry cooler plant at the roof
  • Redundant monitoring and controls
  • Dual A+B power to all components

Access & Security

HID iClass DG access cards for all doors. 24/7 CCTV camera monitoring of the DC rooms and doors in the data center.

Fire detection and suppression

The facility features BOSCH fire detection and suppression system with laser-based Very Early Smoke Detection Apparatus (VESDA). It also has:

  • Multi-zoned detection for all areas
  • Intelligent fire extinguishing system based on environment friendly NAF S 125 gas agent
  • Dual alarms - heat and/or smoke activation

All doors, including power generators, PDU's, UPS, battery, co-location rooms, storage are auto lockable, fireproofed steel doors, that can withstand 72 minutes of open fire without constructive malformations. All cable paths that are room to room crossings are filled in with Intumescent fire-stop sealant. All floors and rooms are equipped with hand-held CO2 & Dry powder fire extinguishers, as required by local fire regulations.
