In this paper, we report the development of fanless single rack data centre (SRDC) which is noise-free and of efficiency in power, energy and operation. SRDC could be deployed as a building block according to different needs and close to users to reduce the latency. Distributed cloud infrastructure constituted by these SRDCs could provide federated computing capability as a large cloud centre. Private cloud could be also implemented according to the application needs. The first prototype of fanless SRDC with a dedicated cooling system is accomplished and verified. It consists of fanless computing nodes with dual CPUs, fanless 12 bays disk servers and a fanless 10G switch with fibre interfaces. Test results show that heat generated by components in each server can bring out effectively by the conductional cooling. The temperature of CPUs can be kept within 60oC under the full load condition. The cooling system modified from the existing air conditioner can achieved PUE < 1.25 in the summer condition.
