Case Study

Digital Realty:
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.
