Using RDMA for Lock Management

Abstract

In this work, we aim to evaluate different Distributed Lock Management service designs with Remote Direct Memory Access (RDMA). In specific, we implement and evaluate the centralized and the RDMA-enabled lock manager designs for fast network settings. Experimental results confirms a couple of hypotheses. First, in the traditional centralized lock manager design, CPU is the bottleneck and bypassing CPU on client-to-server communication using RDMA results in better lock service perofrmance. Second, different lock manager designs with RDMA in consideration result in even better performance; we need to re-design lock management system for RDMA and fast networks.
