CASE STUDY
data centre design & Construction Project
Week 5
Installing Electrical & Fire Suppression Systems
INFINITI IT LIMITED a data centre consultancy and construction specialist has been awarded a "Fast Track" data centre design & build contract for a large global finance company with UK headquarters located in Edinburgh, Scotland.
Over the next 6 weeks we will be providing you with a detailed insight that covers the implementation of a Micro data centre facility. This Blog will cover all installation works right through to final commissioning, witness testing, project completion and handover to our client all within an aggressive 6 week programme.
The design ethos of the data centre facility is scalable and offers our client a complete flexibility with future expansion and will accommodate 100% growth if required, but still ensuring losses are kept to a minimum and that the data centre is as efficient as possible even at lower initial day loads.

Above image shows a critical PDU that provides A & B 32amp feeds to the server and network cabinets. The CPDU (critical power distribution units) are fed from the UPS output via the bypass arrangement.
Above image showing two VESDA aspiration systems and pipework. This particular design is favoured over more traditional and conventional systems that would usually incorporate photo optical smoke heads split over a minimum of two zones that would cover the critical areas, as the air velocity within the cold air floor plenum and hot air ceiling voids can be so great that the detection time can be much longer as compared to an air sampling or aspiration system.
The VESDA units cover one zone each with one system being more sensitive to the other and both panels are connected to the gas panel which is situated on the external wall covering the entrance to the data centre.
Installation of the server and network cabinets along with the hot aisle containment system. The data centre currently supports 6# 600mm x 1000mm x 45U server cabinets and 2# 800mm x 1000mm x 45U network cabinets along with space to install and additional 2# 600mm x 1000mm x 45U server cabinets again to accommodate the clients requirements for future growth and expansion but still ensuring the initial build cost and capital outlay is kept to an absolute minimum.
