| Abstract | As flash devices become ubiquitous in data centers and cost per gigabyte drops, flash systems need to provide data services similar to those of traditional storage. We present Mjölnir, a powerful and scalable engine that addresses the core problems that make efficient flash based data services challenging: multi-reference management and garbage collection. Additionally, by providing powerful primitives for address remapping, Mjölnir enables redesign of the I/O stack for greater efficiency and performance with flash. Mjölnir uses techniques from language runtimes for reference management and garbage collection; we show via prototype and experimental evaluation that this design can deliver predictable performance even with varied user workloads across a range of capacity and reference-count scales. |
