Digital Realty Trust: Data Centre BMS Upgrade

Sirus undertook the upgrade of BMS at Digital Realty’s Blanchardstown Data Centre in 2013/14. The main requirement was to extend the life of the facility and enhance the controls package appearance, functionality, capacity reporting & connectivity.

The Solution

This project was conducted in a live environment and involved upgrading an old Cylon BMS to current Unitron Series Controllers. Modbus interfaces with chillers etc. include:

• Edpac CCU’s (Carel Controllers)
• Stutz CCU’s (C1002 controllers via a MIB network controller)
• Sitewide PDU metering (c.200 meters via a North Integrator back Cylon via Modbus)
• Leak Detection (Tyco TTDM128)

The system is also integrated with site data historian. Extensive metering/monitoring was achieved, including hard and soft solutions:

• 200 DPU meters
• Utilities metering
• UPS metering
• Real-time PUE / COP
• % Capacity Data Suite alerting

In addition to the site upgrade, Sirus completed a Chilled Water System upgrade that ran in parallel with the site upgrade project. This involved a system redesign and change of system operation principles from a 3 port to a 2 port distribution solution. This involved 2# new MCC/DPU’s specifically for the CHW system, all delivered with zero downtime.

The Result

Sirus delivered a greatly enhanced and more user-friendly solution with on and offsite web connectivity with a more robust alerting solution that provides on-call technicians instantaneous plant status anywhere internet connectivity is available. This project was successfully delivered in a Live Data Centre Environment, where the main requirement of zero downtime was achieved thanks to the cooperation between Sirus and Facilities Engineers.
