Title
OBFS: A File System for Object-based Storage Devices
Abstract
The object-based storage model, in which files are made up of o ne or more data objects stored on self-contained Object-Based Storage Devices (OSDs), is em erging as an architecture for distributed storage systems. The workload presented to the OSDs will be q uite different from that of general- purpose file systems, yet many distributed file systems employ general-purpose file systems as their underlying file system. We present OBFS, a small and highly ef ficient file system designed for use in OSDs. Our experiments show that our user-level implement ation of OBFS outperforms Linux Ext2 and Ext3 by a factor of two or three, and while OBFS is 1/25 the size of XFS, it provides only slightly lower read performance and 10%-40% higher write pe rformance.
