Abstract

This work presents a new emulation framework for object-based storage devices (OSDs). The framework integrates an object-based storage emulator with a virtual machine. It resolves the limitations of host CPU resource consumption and network communication overhead found in other frameworks. The storage emulator in the virtual machine runs independently of the emulated CPU, and no network messages are required for communication. The OSD model is compared to a tradition file system on top of a block device. The benchmark results demonstrate an I/O performance improvement of 436% in the best case. The results suggest that the object-based storage architecture is an ideal choice for throughput machines, especially under heavy workloads.
