    Early Experiences with Storage Area Networks and CXFS John Lynch Aerojet 6304 Spine Road Boulder CO 80516 Abstract This paper looks at the design, integration and application issues involved in deploying an early access, very large, and highly available storage area network. Covered are topics from filesystem failover, issues regarding numbers of nodes in a cluster, and using leading edge solutions to solve complex issues in a real-time data processing network. 1 Introduction SAN technology can be categorized in two distinct approaches. Both Aerojet designed and installed a highly approaches use the storage area network available, large scale Storage Area to provide access to multiple storage Network over spring of 2000. This devices at the same time by one or system due to it size and diversity is multiple hosts. The difference is how known to be one of a kind and is the storage devices are accessed. currently not offered by SGI, but would serve as a prototype system. The most common approach allows the hosts to access the storage devices across The project’s goal was to evaluate Fibre the storage area network but filesystems Channel and SAN technology for its are not shared. This allows either a benefits and applicability in a second- single host to stripe data across a greater generation, real-time data processing number of storage controllers, or to network. SAN technology seemed to be share storage controllers among several the technology of the future to replace systems.

  • Designing High-Performance and Scalable Clustered Network Attached Storage with Infiniband
    DESIGNING HIGH-PERFORMANCE AND SCALABLE CLUSTERED NETWORK ATTACHED STORAGE WITH INFINIBAND DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Ranjit Noronha, MS * * * * * The Ohio State University 2008 Dissertation Committee: Approved by Dhabaleswar K. Panda, Adviser Ponnuswammy Sadayappan Adviser Feng Qin Graduate Program in Computer Science and Engineering c Copyright by Ranjit Noronha 2008 ABSTRACT The Internet age has exponentially increased the volume of digital media that is being shared and distributed. Broadband Internet has made technologies such as high quality streaming video on demand possible. Large scale supercomputers also consume and cre- ate huge quantities of data. This media and data must be stored, cataloged and retrieved with high-performance. Researching high-performance storage subsystems to meet the I/O demands of applications in modern scenarios is crucial. Advances in microprocessor technology have given rise to relatively cheap off-the-shelf hardware that may be put together as personal computers as well as servers. The servers may be connected together by networking technology to create farms or clusters of work- stations (COW). The evolution of COWs has significantly reduced the cost of ownership of high-performance clusters and has allowed users to build fairly large scale machines based on commodity server hardware. As COWs have evolved, networking technologies like InfiniBand and 10 Gigabit Eth- ernet have also evolved. These networking technologies not only give lower end-to-end latencies, but also allow for better messaging throughput between the nodes. This allows us to connect the clusters with high-performance interconnects at a relatively lower cost.

  • Analyzing Metadata Performance in Distributed File Systems
    Inaugural-Dissertation zur Erlangung der Doktorwurde¨ der Naturwissenschaftlich-Mathematischen Gesamtfakultat¨ der Ruprecht-Karls-Universitat¨ Heidelberg vorgelegt von Diplom-Informatiker Christoph Biardzki aus Thorn Tag der mundlichen¨ Prufung:¨ 19.1.2009 Analyzing Metadata Performance in Distributed File Systems Gutachter: Prof. Dr. Thomas Ludwig Abstract Distributed file systems are important building blocks in modern computing environments. The challenge of increasing I/O bandwidth to files has been largely resolved by the use of parallel file systems and sufficient hardware. However, determining the best means by which to manage large amounts of metadata, which contains information about files and directories stored in a distributed file system, has proved a more difficult challenge. The objective of this thesis is to analyze the role of metadata and present past and current implementations and access semantics. Understanding the development of the current file system interfaces and functionality is a key to understanding their performance limitations. Based on this analysis, a distributed metadata benchmark termed DMetabench is presented. DMetabench significantly improves on existing benchmarks and allows stress on meta- data operations in a distributed file system in a parallelized manner. Both intra-node and inter-node parallelity, current trends in computer architecture, can be explicitly tested with DMetabench. This is due to the fact that a distributed file system can have different seman- tics inside a client node rather than semantics between multiple nodes. As measurements in larger distributed environments may exhibit performance artifacts difficult to explain by reference to average numbers, DMetabench uses a time-logging tech- nique to record time-related changes in the performance of metadata operations and also protocols additional details of the runtime environment for post-benchmark analysis.

    IRIX® 6.5.15 Update Guide 1600 Amphitheatre Pkwy. Mountain View, CA 94043-1351 Telephone (650) 960-1980 FAX (650) 961-0595 February 2002 Dear Valued Customer, SGI is pleased to present the new IRIX 6.5.15 maintenance and feature release. Starting with IRIX 6.5, SGI created a new software upgrade release strategy, which delivers both the maintenance (6.5.15m) and feature (6.5.15f) streams. This upgrade is part of a family of releases that enhance IRIX 6.5. There are several benefits to this strategy: it provides periodic fixes to IRIX, it assists in managing upgrades, and it supports all platforms. Additional information on this strategy and how it affects you is included in the updated Installation Instructions manual contained in this package. If you need assistance, please visit the Supportfolio Online Web site at http://support.sgi.com or contact your local support provider. In conjunction with the release of IRIX 6.5.10, SGI adopted expanded life cycle management categories to customize the services we deliver to our users. We now offer seven (7) modes of service on SGI software: Active, Maintenance, Legacy, Retired, Courtesy, Divested, and Expired. 2 Active Mode is our highest level of service and applies to products that are being actively developed and maintained. Software fixes for all levels of problems can be expected. Active Mode is for the current release. Prior releases are in Maintenance Mode or Legacy Mode. Maintenance Mode software is maintained and is still an important part of our product mix, but no new functionality is added to it.

    A Survey of the Landscape: Technology for Shared Storage A Guide to SAN Management Software for Mac OS X Updated August 2005 Copyright© 2004-2005 by CommandSoft, Inc. Abstract: This paper gathers and discusses known facts regarding different software products. Authored by the CommandSoft® people, who make the FibreJet® product line, it was written in the “work together” spirit and is encouraged background reading for all customers researching technology for shared storage. Customers are encouraged to perform their own due diligence and ask questions. This paper will be updated from time to time to include new relevant information. We would like to hear from you so send your questions, comments or suggestions to [email protected]. Version 1.0 Released January 2004 Version 1.0.1 Released March 2004 Per readers comments, updated FibreJet section to describe more details about its ability to “claim” and also “unclaim” storage. Also updated this section to describe some database failure situations. This should clarify how FibreJet behaves in these situations. Version 1.0.2 Released August 2005 Added Xsan section. Update FibreJet, ImageSAN, SANmp and Charismac sections to reflect latest findings. SAN Background A Storage Area Network (SAN) is a network that allows computers to be connected to storage devices in a fashion that allows many computers to connect to many storage devices. Before SANs, storage was normally connected to only one computer at any given time, with few exceptions. ONE-TO-MANY — STORAGE CONNECTED TO ONE COMPUTER As more general purpose, and longer distance connection technologies such as fiber optics and the Fibre Channel protocol were developed, these SAN options became available to general computer users.
