Abstract

This paper proposes a utilitarian performance isolation (UPI) scheme for shared SSD settings. UPI exploits SSD's abundant parallelism to maximize the utility of all tenants while providing performance isolation. Our approach is in contrast to static resource partitioning techniques that bind parallelism, isolation, and capacity altogether. We demonstrate that our proposed scheme reduces the 99th percentile response time by 38.5% for a latency-critical workload, and the average response time by 16.1% for a high-throughput workload compared to the static approaches.
