    The European Centre for Medium-Range Weather Forecasts (ECMWF) has for many years operated a large mass-storage system based on CFS/DataTree. The CFS system will need replacement before the end of the decade, and ECMWF accordingly embarked on a study of available systems which might be suitable. What we found was that, for various reasons, none of the systems available on the market met our needs.... View full abstract»

    A video-on-demand (VOD) storage server is a parallel, storage-centric system used for playing a large number of relatively slow streams of compressed digitized video and audio concurrently. Data is read from disks in relatively large chunks, and is then "streamed" out onto a distribution network. The primary design goal is to maximize the ratio of the number of concurrent streams to system cost wh... View full abstract»

    Datasets up to terabyte size and petabyte total capacities have created a serious imbalance between I/O and storage-system performance and system functionality. One promising approach is the use of parallel data-transfer techniques for client access to storage, peripheral-to-peripheral transfers, and remote file transfers. This paper describes the parallel I/O architecture and mechanisms, parallel... View full abstract»

    Distributed on-line transaction processing (OLTP) technology can be applied to distributed mass storage systems as the mechanism for managing the consistency of distributed metadata. OLTP concepts are familiar to many industries, such as banking and financial services, but are less well known and understood in others, such as scientific and technical computing. However, as mass storage systems and... View full abstract»

    Most modern high performance storage systems store data in large repositories of removable media volumes. Management of the removable volumes is performed by a software module known as a physical volume library (PVL). To meet performance and scalability requirements, a PVL can be asked to mount multiple removable media volumes for use by a single client for parallel data transfer. Mounting sets of...

    Shared file systems which use a physically shared mass storage device have existed for many years, although not on UNIX based operating systems. This paper describes a shared file system (SFS) that was implemented first as a special project on the Gray Research Inc. (CRI) UNICOS operating system. A more general product was then built on top of this project using a HIPPI disk array for the shared m... View full abstract»

    Tertiary storage devices have long been in use for storing massive amounts of data in file-oriented mass storage systems. However, their use in database systems is relatively new. Database systems associate more structure to the data than just raw sequence of bytes. Hence, if they are allowed control of the tertiary memory devices, they can greatly reduce access cost by performing informed caching... View full abstract»

    We propose an architecture for scalable persistent object managers that provide access to large numbers of objects distributed over a variety of physical media. Our approach is lightweight in that we are interested in providing direct support for the creation, access, and updating of persistent objects, but only indirect support for the other functions traditionally associated with an object orien...

    In 1990, a technical team at NASA Lewis Research Center, Cleveland, Ohio, began defining a mass storage service to provide long-term archival storage, short-term storage for very large files, distributed NFS access, and backup services for critical data that resides on workstations and PCs. Because of software availability and budgets, the total service was phased in over three years. During the p... View full abstract»

    We estimate the performance of a network-wide concurrent file system implemented using conventional disks as disk arrays. Tests were carried out on both single system and network-wide environments. On single systems, a file was split across several disks to test the performance of file I/O operations. We concluded that performance was proportional to the number of disks, up to four, on a system wi... View full abstract»

    We evaluate storage system alternatives for movies-on-demand video servers. We begin by characterizing the movies-on-demand workload. We briefly discuss performance in disk arrays. First, we study disk farms in which one movie is stored per disk. This is a simple scheme, but it wastes substantial disk bandwidth, because disks holding less popular movies are underutilized; also, good performance re... View full abstract»
