Network support for resource disaggregation in next-generation datacenters

Sangjin Han, Norbert Egi, Aurojit Panda, Sylvia Ratnasamy, Guangyu Shi, Scott Shenker
2013 Proceedings of the Twelfth ACM Workshop on Hot Topics in Networks - HotNets-XII  
In this paper, we advocate an alternative construction in which the resources within a server are disaggregated and the datacenter is instead architected as a collection of standalone resources.  ...  This paper thus explores the question of whether we can build networks that enable disaggregation at datacenter scales.  ...  For I/O traffic, such as network interfaces and disks, the required latency and bandwidth level is sufficiently low to consolidate them within the unified network.  ...
