AUTOBAHN: Accelerating Concurrent, Durable File I/O via a Non-volatile Buffer
2017 IEEE International Conference on Cluster Computing (CLUSTER)(2017)
摘要
As hardware vendors provision more cores and faster storage devices, attaining fast data durability for concurrent file writes is demanding to high-performance storage systems in cluster systems. We approach the challenge by proposing a system that uses a small amount of fast persistent memory for buffering concurrent file writes while preserving data durability. The main issue in designing a durable file buffer is allowing concurrent file writes to store data in a shared and limited space of persistent memory without incurring lock or resource contention. This paper addresses such issue and presents AUTOBAHN, a durable file buffer that expedites file I/O operations.
