Retailer data centre critical upgrade

Case Study

Due to problems with this large retailer’s old data centre Sudlows DMCC were awarded a contract via a competitive tender to upgrade the existing facility to a concurrently maintainable MEP infrastructure and provide a new data hall for expansion.

The Brief

The new data centre had to be on the same site as the existing facility and was to re-use some of the existing capacity equipment such as the UPS systems and generator.

A challenge was presented in the retailer’s current data centre being at capacity both from power and floor space. This facility needed to be kept live at all times and migrated to the new electrical infrastructure without any downtime.


The Sudlows DMCC team optimised the layouts for the electrical room and data hall. This made the maintenance easier and provided a greater number of racks which allowed the retailer to make their old data centre redundant after migration to the new facility.

Various scenarios were considered before the decision was made to move the existing IT load and UPS systems on to the new electrical infrastructure, giving the retailer peace of mind during the risky activity. This risk was reduced where possible with the time that the IT was on ‘N’ kept to a minimum while the facility ran on a generator.
