    In computer systems today, speed and responsiveness is often determined by network and storage subsystem performance. Faster, more scalable networking interfaces like Fibre Channel and Gigabit Ethernet provide the scaffolding from which higher performance implementations may be constructed, but new thinking is required about how machines interact with network-enabled storage devices. We have devel... View full abstract»

    The supercomputer center, digital library, and archival storage communities have common persistent archival storage requirements. Each of these communities is building software infrastructure to organize and store large collections of data. An emerging common requirement is the ability to maintain data collections for long periods of time. The challenge is to maintain the ability to discover, acce... View full abstract»

    In common with many large institutes, CERN has traditionally developed and maintained its own data management solutions. Recently, a significant change of direction has taken place and we have now adopted commercial tools, together with a small amount of site-specific code, for this task. The solutions chosen were originally studied as part of research and development projects oriented towards the... View full abstract»

    With an ever increasing amount of data to store, hierarchical storage management (HSM) systems must still use tape for tertiary storage. A disk cache is used to reduce the access time to data stored on tapes in a robot device. Due to the sequential access to tape devices, some HSM systems will transfer whole files between disk cache and tape. In this case the disk cache is forced to handle storage... View full abstract»

    When the BaBar experiment at the Stanford Linear Accelerator Center starts in April 1999, it will generate approximately 200 TB/year of data at a rate of 10 MB/sec for 10 years. A mere six years later, CERN, the European Laboratory for Particle Physics, will start an experiment whose data storage requirements are two orders of magnitude larger. In both experiments, all of the data will reside in O... View full abstract»

    According to the current profound development of multimedia and networking technologies, the way people communicate with, naturally, has evolved from a text-oriented into a multimedia-oriented. But, the VOD system technologies can't be easily applied to MNOD system because of the difference of tile basic data and its properties. This is the reason why we propose the MNOD system.

    The bandwidth performance of a Fibre Channel Arbitrated Loop (FCAL) is roughly defined to be 100 MegaBytes (100 bytes) per second. Furthermore, FCAL is capable of a theoretical peak of 40,000 I/O operations (transactions) per second. These performance levels, however, are largely not realized by the applications that use Fibre Channel as an interface to disk subsystems. The bandwidth and transacti... View full abstract»

    Several parameters play an important role in the design of tape subsystems. This paper analyzes some of these parameters and their relationships in determining the capacity and throughput of the tape subsystem. The pros and cons of trade offs among these parameters are also offered in choosing the right values for these parameters View full abstract»

  • Finding coincident data from satellites: using “meta-metadata” to reduce load on archive

    Publication Year: 1999, Page(s):252 - 261
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1068 KB)

    In this paper, the concept of “meta-metadata” is introduced as an abstraction of metadata as metadata is an abstraction of the data. The problem of finding coincident data from satellites is examined using metadata and meta-metadata. The meta-metadata approach is shown to be more generally applicable and supports a more heterogeneous system. Finally, the implementation of a prototype s... View full abstract»

  • Hiding HSM systems from the user

    File life-times longer than the life-time of HSM-systems make it necessary to move files from one HSM-system to another. Such a migration takes a long time and cannot be hidden from the user unless an additional layer of software is put in between. RZG is using MR-AFS as such a layer. The features of MR-AFS are presented once again. RZG's experiences with HSM-migrations and the usage patterns of M... View full abstract»

    This paper shows the suitability of a “self-maintaining” approach to Tertiary Disk, a large-scale disk array system built from commodity components. Instead of incurring the cost of custom hardware, we attempt to solve various problems by design and software. We have built a cluster of storage nodes connected by switched Ethernet. Each storage node is a PC hosting a few dozen SCSI disk... View full abstract»

    We present recommendations on Performance Management for databases supporting Binary Large Objects (BLOB) that, under a wide range of conditions, save both storage space and database transactions processing time. The research shows that for database applications where ad hoc retrieval queries prevail, storing the actual values of BLOBs in the database may be the best choice to achieve better perfo...

    As disk capacities continue to rise more rapidly than transfer rates, adaptive, redundant striping smoothly trades capacity for higher performance. We developed a fuzzy logic rule base for adaptive, redundant striping of files across multiple disks. This rule base is based on a queuing model of disk contention that includes file request sixes and disk hardware parameters. At low loads, the rule ba... View full abstract»

    Archival storage systems must operate under stringent requirements, providing 100% availability while guaranteeing that data will not be lost. In this paper we explore the multiple interconnected subsystems that must be tuned to simultaneously provide high data transfer rates, high transaction rates, and guaranteed meta-data backup. We examine how resources must be allocated to the subsystems to k... View full abstract»

    When a serpentine tape drive is used as a slow random access device, the I/O performance can be substantially improved by clever re-ordering of the I/O requests. This kind of re-ordering relies on a scheduling algorithm and a model of the access time. In this paper, we propose a low-cost access time model for serpentine tape drives, which is not a trivial task due to the complex data layout of ser... View full abstract»

    Device Locks are mechanisms used in distributed environments to facilitate mutual exclusion of shared resources. They can further be used to maintain coherence of data that is cached in several locations. The locks are implemented on the storage devices and accessed with the SCSI device lock command, Dlock. The paper presents the Dlock command and discusses how it can be used as a mutual exclusion... View full abstract»
