The datacenter today is almost everybody’s other computer. The primary computer is increasingly a mobile device such as a smart phone, tablet, or laptop. The bulk of both the computing and the storage is done in the datacenter since the mobile devices are energy constrained. Datacenters vary in both the size and the performance of the constituent components. They vary from large-scale supercomputers, through warehouse scale installations supporting social networking, cloud services, etc. to smaller scale enterprise or university installations. In 2011, 2% of the US energy consumption went to support this computing model and the growth in both the number and size of datacenter installations leads to an alarming energy consumption scenario. This chapter focuses on the potential role of optical/photonic communication technology and the impact that this technology may have on future energy-efficient datacenters. |
