The NPL Data Center (NPLDC) previously contained a single high performance cluster, ATHENA, and now provides the infrastructure to multiple clusters and department appliances. The ATHENA high performance computing (HPC) cluster has evolved into multiple smaller computational clusters. One of these clusters, CENPA, currently runs a Rocks 5.3 cluster which provides computing power to CENPA faculty and students. We are investigating the possibility of scaling the cluster to a hybrid cloud by leveraging publicly available clouds resources. In addition, NPLDC supports a wide range of server appliances: virtual web/wiki/gateway servers, SQL servers, ﬁle servers, backup servers, shared storage arrays and security appliances.
