Object based storage devices (OSDs) elevate the level of abstraction presented to clients, thereby permitting them to offer methods for managing, sharing, and securing information that go beyond those offered by block-based stores. The Object-Oriented Storage System (O2S2) architecture presented and evaluated in this paper provides object-based storage in a virtualized environment. This service provides a virtual object-based storage device (vOSD) to virtual machines. The use of vOSDs permits the service provider, i.e., the vOSD storage domain, to offer to guest virtual machines new methods for resource management and consolidation Methods demonstrated in this paper include improved support for access control and for heterogeneity of storage devices. A prototype PVFS-based O2S2 implementation demonstrates that its enhanced services can be provided at low cost, enabled in part by the efficient utilization of otherwise idle storage domain resources.
