EMI: A Rack-scale Memory Interconnection Network Architecture

Abstract

Big data processing applications more and more demand for memory, especially data-intensive applications. The emergence of large-scale storage media supplies for the expansion of memory scale. As a consequence, the interconnection of memories is a key factor to be considered. This paper presents a memory interconnection network architecture for rack-scale supporting for dynamic allocation and expansion of memory, EMI (Elastic Memory Interconnection). EMI’s topology belongs to a hierarchical design approach to extend the network to rack-scale. We also explore the interconnection within every layer, as far as possible to do low latency communications and improve local performance.
