Microsoft DUB05 is the third data centre on Microsoft's original Grange Castle campus in Clondalkin, west Dublin. It sits just south of the connected DUB03 and DUB04 buildings.
Microsoft announced the €170 million ($230 million) expansion in December 2013 and completed it in spring 2014. The single-storey building covers 15,700 m² (169,000 sq ft). It brought the original campus (DUB03 to DUB05) to 54,255 m² (584,000 sq ft) of buildings and total investment to €594 million.
Rooftop air handling units cool the data halls with outside air through an air-to-air heat exchanger. The units run in dry mode about 95% of a typical year. An evaporative mode supports them on the hottest days. The building uses no chillers.
ESB Networks serves the campus from the Kilmahud 110 kV customer substation, built next to DUB03 and switched in during January 2010. EirGrid operates the transmission system. West Dublin's grid is constrained, and later Microsoft buildings at Grange Castle needed on-site gas generation. No behind-the-meter generation serves DUB05.
Fifteen containerised diesel generators with integrated belly tanks back up DUB05, in a generator yard south of the building. Microsoft is trialling hydrotreated vegetable oil (HVO) as a diesel substitute across DUB03 to DUB05.
Microsoft has since built DUB06 through DUB15 on a second campus to the east and south within Grange Castle Business Park.

Microsoft uses Containers (called ITPACs) to build out its data centers. These Containers are Shipping Containers fitted with all the necessary climate control, networking, server racks and other hardware necessary to be a “mini” data center all in one.
An Azure region is a set of data centers deployed within a latency-defined perimeter and connected through a dedicated regional low-latency network.
With more global regions than any other cloud provider, Azure gives customers the flexibility to deploy applications where they need to. Azure is generally available in 46 regions around the world, with plans announced for 8 additional regions.
An Azure geography is a discrete market, typically containing two or more regions, that preserves data residency and compliance boundaries.
Geographies allow customers with specific data-residency and compliance needs to keep their data and applications close. Geographies are fault-tolerant to withstand complete region failure through their connection to our dedicated high-capacity networking infrastructure.
Availability Zones are physically separate locations within an Azure region. Each Availability Zone is made up of one or more data centers equipped with independent power, cooling, and networking.
Availability Zones allow customers to run mission-critical applications with high availability and low-latency replication.
