Profiling and Benchmarking of Openstack Swift Object Storage

Abstract: Openstack object storage system (swift) being increasingly recognized as preferred way to expose one‟s storage infrastructure as a service. Openstack object storage is a scalable redundant storage system. Objects and files are written to multiple disk drives spread throughout servers in the data center, with the OpenStack software responsible for ensuring data replication and integrity across the cluster. As Swift is extremely dynamic and flexible, it needs to be tested under various load scenarios to monitor its performance. It is very challenging to evaluate its performance under various workloads. To address this problem we are building up a solution which benchmark the object store with different load characteristics and provide us with detailed statistics.
