Ceph Distributed File System Benchmarks on an Openstack Cloud
Xiaolu Zhang, Suman Reddy Gaddam, Anthony Theodore Chronopoulos · 2015
Ceph is a distributed file system that provides high performance, reliability, and scalability. Ceph maximizes the separation between data and metadata management by replacing allocation tables with a pseudo-random data distribution function (CRUSH) designed for heterogeneous and dynamic clusters of unreliable object storage devices (OSDs). In this paper, we investigate the performance of Ceph on an Open Stack cloud using well-known benchmarks. Our results show its good performance and scalability.
