Abstract
Disaggregation of IT resources has been proposed as an alternative configuration for data centres. Comparing to the monolithic server approach that data centres are being built now, in a disaggregated data centre, CPU, memory and storage are separate resource blades and they are interconnected via a network fabric. That brings greater flexibility and improvements to the future data centres in terms of utilization efficiency and energy consumption. The key enabler for the disaggregated data centre is the network, which should support the bandwidth and latency requirements of the communication that is currently inside the server. In addition, a management software is required to create the logical connection of the resources needed by an application. In this paper, we propose a disaggregated data centre network architecture, we present the first scheduling algorithm specifically designed for disaggregated computing and we demonstrate the benefits that disaggregation will bring to operators.Keywords
