Abstract: A data centre comprises a plurality of sections assembled together to define a unitary structure such that there exists at least one personnel area that spans at least two sections; wherein the sections comprise a first section with which there is associated a first service-carrying chassis and a second section with which there is associated a second service-carrying chassis, each of the first and second service-carrying chassis comprising a frame onto which is mounted components of at least two different services; the first and second chassis are connected to each other by means of a junction between the first and second chassis; and the first and second sections each include a ceiling and the first service carrying chassis is mounted on the ceiling of the first section and the second service carrying chassis is mounted on the ceiling of the second section.

Abstract: A data center comprises a plurality of sections (15a-15h) assembled together to define a unitary structure (10) such that there exists at least one personnel area that spans at least two sections; wherein the sections comprise a first section with which there is associated a first service—carrying chassis (40, 50, 60, 70) and a second section with which there is associated a second service—carrying chassis 40, 50, 60, 70), each of the first and second service—carrying chassis comprising a frame (41, 51, 61, 71) onto which is mounted components of at least two different services (42-44, 46); the first and second chassis are connected to each other by means of a junction (47) between the first and second chassis; and the first and second sections each include a ceiling (22) and the first service carrying chassis is mounted on the ceiling of the first section and the second service carrying chassis is mounted on the ceiling of the second section.

Abstract: A data center (100) includes at least one rack room (in for example module 140) having a floor and a plurality of rack storage areas on the floor, each rack storage area being arranged to accommodate a plurality of racks (143) in which a plurality of rack-mountable electronic components may be housed, one or more controllable air circulation systems (in for example module 122), one or more cold aisles (144) in the rack room, each cold aisle being adjacent to a rack storage area, and one or more hot aisles (145) in the rack room, each hot aisle being adjacent to a rack storage area. There may be a large air duct, in the form of a personnel corridor (123), for transporting, under the control of the one or more air circulation systems, cooling air, above the floor, to the one or more cold aisles. The air supply corridor/duct (123) may have a height greater than 1.5 m above the floor and a cross-sectional area of at least 2 m2 and a maximum dimension in the plane of the cross-section of less than 3 m.
