Object-based storage systems represent files as sets of objects stored on self-contained Object-Based Storage Devices (OSDs). By distributing the objects across many devices, these systems have the potential to provide high capacity, throughput, reliability, availability and scalability.

The object-based storage model, in which files are made up of one or more data objects stored on self-contained Object-Based Storage Devices (OSDs), is emerging as an architecture for distributed storage systems.

Object-based storage is a promising alternative • Scalable • Supports parallel access • Highly distributed metadata and data management Storage management needs to adapt to this new model • File and object storage are fundamentally different • …

In this paper, we present OMX-FS, a multi-user distributed object-oriented file system, based on the generic object model OM. OMX-FS considers files as objects and introduces concepts typical of object-oriented database systems, enabling both application developers and users to interact with the file system at a higher-level of logical abstraction.

Apr 1, 1995 · This paper presents the design of an object-oriented file system which was developed as a part of the "OBJIX Object-Oriented Operating System" project. The file system is a self-contained program system which is decomposed using a standard object-oriented framework concept.

We present Naked Objects File System (NOFS), a novel framework that allows a developer to expose a domain model as a file system by leveraging the Naked Objects design principle. NOFS allows a developer to construct a file system without having to understand or implement all details related to normal file systems development.

Nov 17, 2009 · This paper presents a versatile object-based file system (referred to as V-OBFS), an extent and B+tree based file system designed for use in OSDs. The V-OBFS implements flexible disk layout with multiple block size and differentiated free space management for both small objects and large objects.

analyzes various aspects of object based storage such as file system design, application based optimizations and so on, in order to understand the advantages of this upcoming storage technology.

We present Naked Objects File System (NOFS), a novel framework that allows a developer to expose a domain model as a file system by leveraging the Naked Objects design principle. NOFS allows a developer to construct a file system without having to understand or implement all details related to normal file systems development.

We present OBFS, a very small, highly efficient object-based file system developed for use in OSDs in large-scale distributed storage systems. The basic idea of OBFS is to optimize the disk layout based on our knowledge of the workload.
