The site was a Telecity managed datacenter before Equinix acquired Telecity in July 2016. It was known as "TeleCity STO2" when operated by Telecity.
Power:
- Stockholm II provides robust and reliable power with flexible power densities and configuration between 2 and 20kW per rack.
- 8 MW of UPS conditioned power at N+1.
- Dual redundant 10 kV HV power system from separate grids and dual redundant feed.
- Backup diesel generation at N+1 to support site load during HV failure.
- Maximum diversity and separation of UPS system and power distribution through dedicated A & B supplies.
Cooling:
A robust HVAC system delivers stable air flow, temperature and humidity for efficient equipment operation. All major equipment in the HVAC system has a minimum of N+1 redundancy and its own dedicated back-up generators/ UPS. Our design and investment in cooling systems will ensure the data centre achieves a PUE of 1.31.
- Minimum N+1 redundancy on chilled water-cooling system.
- Two independent secondary chilled water cooling systems enhance resilience.
- Close Control Units (CCUs) provide conditioned air to the data floor, at a minimum N+1 redundancy.
- Air-cooled chillers maximise the use of free cooling.
- Centrifugal chillers with variable speed compressor drives enable excellent full and part-load operation.
