Description
The HEPiX meetings bring together IT system support engineers from the High Energy Physics (HEP) laboratories and institutes, such as BNL, CERN, DESY, FNAL, IN2P3, INFN, JLAB, NIKHEF, RAL, SLAC, TRIUMF and others. They have been held regularly since 1991, and are an excellent source of information for IT specialists. That's why they enjoy large participation also from the non-HEP organizations.

        Inspire
        Inspire is the project name of a new High Energy Physics information system which will integrate present databases and repositories to host the entire corpus of the HEP literature and become the reference HEP scientific information platform worldwide. It is a common project between CERN, DESY, FERMILAB and SLAC. It will empower scientists with new tools to discover and access the results most relevant to their research; enable novel text- and data-mining applications; deploy new metrics to assess the impact of articles and authors. In addition, it will introduce the Web2.0 paradigm of user-enriched content in the domain of sciences with community-based approaches to the peer-review process.

        Updates and Experiences from the Genome Center's Data Center Construction Project
        Over the last couple of years, The Genome Center at Washington University in St. Louis has been involved with the planning and construction of a new data center. We will provide updates since our data center presentation at HEPiX Fall 2007 in St. Louis. In addition, we will share our experiences and lessons learned as we prepare to move into the new data center in May 2008.

        AFS Monitoring: The CERN AFS Console
        CERN's AFS installation serves between 1 and 2 billion accesses per day to its around 20'000 users. Keeping track of the system's overall status and trying to find problems before the users do is not a trivial task, esp. as the installation is growing in almost all aspects. This talk will present CERN's AFS Console, a Lemon- and web-based monitoring tool used by the AFS administrators at CERN to quickly identify problematic entities (servers, partitions, volumes etc.) and to assist them in solving the issues found.

        New Data Center at BNL -- Status Update
        This presentation provides an update on the status of the new Data Center to support the ATLAS Tier 1 Center and RHIC Computing at Brookhaven. A brief discussion provides details of the new facility to Brookhaven, as well as timelines for availability to both the ATLAS and RHIC programs. Some of our experiences described in this presentation will also be beneficial to other sites who are considering expansion of their own facilities.

        A Service-Based SLA Model
        The RACF provides computing support to a broad spectrum of programs at Brookhaven. The growth of the facility, the varying needs of the scientific programs and the necessity for distributed computing requires the RACF to change from a system to a service-based SLA with our end users. This presentation describes the adjustments made by the RACF to transition to a service-based SLA, including changes to its monitoring, alarm notification and problem resolution policies at the facility.

        CluMan
        Managing large clusters that host complex services has particular challenges. Operations like checking configuration consistency, running some actions on node or nodes, moving them between clusters etc. are very frequent. When scaling up to running thousands of CPU and STORAGE nodes in order to meet LHC requirements some of these challenges are becoming more evident. These scaling challenges are the basis for CluMan, a new cluster management tool being designed and developed at CERN.

        The unbearable slowness of tapes
        It is still common for the lowest layer of data storage to be 'tape'. While individual tape devices apparently offer very good performance, this is only achieved in a limited set of circumstances, and the overall throughput can easily become very poor very quickly. How can this be avoided, if at all? Is it sufficient to just add more and more equipment? These difficulties will be discussed in the context of CERN's current CASTOR HSM version, and the need to 'carry LHC data forward' for many years.

        Experience and Lessons learnt from running high availability databases on Network Attached Storage
        The Database and Engineering Services Group of CERN's Information Technology Department provides the Oracle based Central Data Base services used in many activities at CERN. In order to provide High Availability and ease management for those services, a NAS (Network Attached Storage) based infrastructure has been set up. It runs several instances of the Oracle RAC (Real Application Cluster) using NFS as share disk space for RAC purposes and Data hosting. It is composed of two private LAN's to provide access to the NAS file servers and Oracle RAC interconnect, both using network bonding. NAS nodes are configured in partnership to prevent having single points of failure and to provide automatic NAS fail-over. This presentation describes that infrastructure and gives some advice on how to automate its management and setup using a Fabric Management framework such as Quattor. It also covers aspects related with NAS Performance and Monitoring as well Data Backup and Archive of such facility using already existing infrastructure at CERN.

        A redundant Servercluster using SL5.1 and Xen
        Howto build a redundant (failover) Servercluster using Scientific Linux 5.1 with Xen. The services (filer, dns, dhcp, printing etc.) will be divided into individual virtual machines to isolate the services. On failure of a server, the services will be relocated automatically. The system is using a redundant Fibrechannel storage as the shared storage, but same would be possible using other techniques. The talk shows the architecture of the system, as well as some problems we found both in the SL Clustersoftware and SL's Xen Implementation and how we avoid them.

        Benchmarking Multi-core Processors in the NERSC Production Environment.
        Results of benchmarking based on HENP production codes from single, dual and quad - core processors will be presented. We will look at ratios of CPU/wall clock, memory consumption and I/O performance of those codes on the latest additions to the PDSF production systems.

        IPv6 experience in a mixed unix environment
        We have been using the Academic Computer Club at Umeå University as our testbed for IPv6 deployment, this includes some popular public services like a rather big free software mirror as well as workstations and multi-user machines in a semi-production environment. This talk gives an overview of the various pitfalls as well as what "just works", with some pointers on what kind of systems and software need attention.

        Advanced Monitoring Techniques for the Atlas TDAQ Data Network
        We describe the methods used to monitor and measure the performance of the Atlas TDAQ data network. The network consists of four distinct Ethernet networks interconnecting over 4000 ports using up to 200 edge switches and five multi-blade chassis. The edge networks run at 1Gbps and 10Gb/s are used for the detectors raw data flow as well as at the cores of the data flow networks. The networks feed event data to farms of up to 3000 processors. Trigger applications running on these processors examine each event for acceptability and assemble the accepted events ready for storage and further processing on Grid linked data centers. We report in detail on the monitoring and measurement techniques deployed and developed.

        Operational security in a grid environment
        This talk presents the main goals of computer security in a grid environment, by using a FAQ approach. It details the evolution of the risks in the recent years, likely objectives for attackers and the progress made by the malware toolkits and frameworks. Finally, recommendations to deal with these threats are proposed.
