DoC Private Cloud Hardware Investigations
CSG are investigating the hardware that could be used to realise the DoC cloud. We have identified two basic infrastructure and server requirements; we provide details and cost estimates on this page. The basic idea is that we buy two of everything and then one nominal rack in the Huxley 221 Data Centre containing half the equipment and another nominal rack in the ICT Mech Eng Data Centre containing the remaining half.

Server requirements
We identify two type of server for the DoC private cloud: a compute node and a storage node. A compute node contains a large number of CPUs/cores. Its primary role in the cloud is one of computation (virtual machine hosting, distributed computing and the like). A storage node contains a large local (or directly attached) storage capacity. Its primary role in the cloud is to provide storage (for compute nodes and to house distributed file-systems).
Compute Nodes
We have considered a number of manufacturers for compute nodes including IBM, Dell and HP. We want dense compute nodes (a large number of CPUS/cores per cubic volume) so as to make best use of rack-space, power and cooling requirements notwithstanding. We have found that Dell offer the densest server configurations in the form of the PowerEdge C6000 series. We identify two servers in particular: the AMD-based Dell PowerEdge C6145 and the Intel-based Dell PowerEdge C6220
