Data Center Infrastructure

Cooling

Our data center infrastructure features N+1 design. The climate is controlled by way of precision air condition systems. CoreLink has 20-ton and 30-ton Computer Room Air Conditioners (CRAC) units located in each colocation room. CRAC units are piped to cooling towers, chillers or condensers located in a secured exterior area.

The CRAC units are set to 72 degree set-point, and continuously monitor the data center environment within a 2 degree tolerance, and add humidity, cool or heat as needed to maintain that set point condition.

CoreLink’s data center infrastructure also has temperature and humidity sensors located in each colo rooms to ensure that environmental conditions are appropriate and stable.

A number of methods are used to handle higher densities, and sound operational practice:

• Our data center infrastructure is designed, engineered and operated based on industry best-practices
• All customers go through a data center design review once requirements are gathered. We ensure that we adhere to our data center design
• Hot-row, cold-row data center infrastructure configurations
• 42" deep cabinets not only allow the necessary room for today's deeper servers, but also allow for better cable management to ensure that airflow from the servers is not blocked
• Blanking panels in all open RU space to prevent bypass-air and hot air recirculation
• Under floor plenum with minimal to no obstructions
• Metered PDUs are used to ensure no circuit loading goes unnoticed, as well as provide critical input for capacity management
• Higher than standard density requirements are met with either passive cooling methods, such as those available from Chatsworth (Vertical Exhaust Duct System), or active supplemental cooling methods, such as those available from APC (in-row cooling)
