In one example of the storage unit, a plurality of storage spaces, each storage space configured for storing a data processing system, is provided. An air inlet duct and an air outlet duct allow air circulation within the storage unit. A plurality of inlet conduits, each inlet conduit configured to connect the inlet air duct to an inlet port of a data processing system, provides air supply to the data processing system. A plurality of outlet conduits, each outlet conduit configured to connect the outlet air duct to an outlet port of a data processing system, provides air exhaust from the data processing system. The example storage unit may also provide a primary air transfer system configured for directing air into the air inlet duct and/or for extracting air from the air outlet duct. ## Claims ### Claim 1 A data processing system storage unit for storing a plurality of data processing systems, comprising: a plurality of storage spaces, wherein each storage space is configured for storing a data processing system;
