The physical infrastructure, the software, and the demands placed upon the data center vary moment by moment, day by day. Dynamic data center environments are always in flux – changing hardware, changing workloads, changing layouts, changing goals. Waste not, want not. Capital efficiency at times demands that we reuse existing infrastructure, often when something shiny and new is more attractive or more convenient. There are many parts of the data center that can be reused or refitted to accommodate the latest and greatest servers, accelerators, storage, and networking. This white paper makes the case for reducing the electronic waste stream during the refresh cycle of the data center through reuse of the racks, PDUs, and other long-life items.
