Many application classes, such as archiving, backup of thousands of nodes in an organization, video sharing, etc., require highly reliable and scalable storage systems. Since it is now feasible to build such storage systems with advanced open source technologies, the challenge becomes how to best utilize those technologies to build and operate such a storage system with optimized cost and performance. The focus of this work is to provide an effective solution and key insights for this challenge within the context of the OpenStack Object Storage (Swift) platform.

The OO7 Benchmark was first published in 1993, and has since found a home in the marketing literature of various object-oriented database management system (OODBMS) vendors. The OO7 Benchmark (as published) was the initial result of an ongoing OODBMS performance evaluation effort at the University of Wisconsin. This paper provides an update on the status of the effort on two fronts: single-user and multi-user. On the single-user front, we review and critique the design of the initial OO7 Benchmark. We discuss some of its faults, the reasons for those faults, and things that might be done to correct them. On the multi-user front, we describe our current work on the development of a multi-user benchmark for OODBMSs. This effort includes changes and extensions to the OO7 database and the design of a family of interesting multi-user workloads.
