Description
The HEPiX forum unifies 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. The HEPiX meetings 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.

Windows Vista and Office 2007 deployments at CERN 30mWindows Vista has been released by Microsoft early this year and Office 2007 even at the end of the last year. First, in March 2007, Office 2007 pilot has been announced at CERN. This new Office suite version is now pre-installed on each new computer at CERN. In addition users can upgrade to Office 2007 their existing PCs. With such deployment schema we currently have Office 2007 installed on 15% of Windows PCs. Then, in August, Windows Vista pilot started. It took us some time and effort to test this new operating system and tune to our needs before we could give it to the end users. Currently we have more than 100 Vista computers in production at CERN.Speaker: Mr Rafal Otto (CERN)

Advanced Group Policy Management 30mGroup Policy Objects (GPOs) have a pole position in a domain network management. Unfortunately, the primary tool for managing Group Policy in an enterprise, the Group Policy Management Console (GPMC), doesn’t provide a base for a workflow in any but the simplest management models. Microsoft Advanced Group Policy Management (AGPM), the technology included in the Microsoft Desktop Optimization Pack for Software Assurance for the Microsoft Windows Vista, addresses the problem and adds the needed functionality. It increases the capabilities of the GPMC, providing offline editing of GPOs, role-based delegation of control, check-in/check-out capability, GPO templates, version control and rich reporting.Speaker: Kazimierz Popinski (DESY)

Update on Chimera and NFS v4.1 30mWith the start of the Large Hadron Collider, presumably in 2008, the largest share of the produced and generated physics data outside CERN will be managed by the dCache storage element. Beside the challenge to handle storage in the order of tens of Petabyte in a single installation, the number of file operations per second is certainly even more challenging. Two years ago we identified PNFS, the dCache file system component, as to be the part which may become a bottleneck at the point in time when the global LHC data chain will be operated at its full capacity. There are various reasons for this assumption. Due to the fact, that pnfs existed before dCache was designed, dCache and pnfs interact by means of the nfs2 protocol, which introduces an nonessential layer of complexity. Moreover, although pnfs is using the Postgres database, it doesn't make use of enhanced modern database functionalities. Another striking issue is certainly the fact that single read/write locks are used internally, protecting large collection of file which leads to unnecessary queuing of file operation requests. To circumvent those and many other issues we designed and implemented Chimera, a file system name space engine based on the Java programming language as well as on modern database technologies. Furthermore, Chimera is an inevitable prerequisite in dCache to support the NFS 4.1 protocol. NFS 4.1 is currently in its final state of specification. As to our current plans NFS 4.1 will be supported in dCache in the foreseeable future. This presentation will give more insight in the advantages of Chimera and the NFS 4.1 plans of the dCache team.Speaker: Mr Peter van der Reest (DESY - IT)

HA and Virtualization team @ INFN 20mVirtualization can enhance the functionality and ease the management of current and future Grids by enabling on-demand creation of services and virtual clusters with customized environments, dynamic provisioning and policy-based resource allocation, as well as enhance high availability and load balancing techniques. In this work, we consider the work done in the last year in different INFN sections in both fields. We present a summary of the activity reports sent by each team. At first we provide statistics and metrics of virtualization solutions for Tier-2 core services implemented in production; then a prototype of the use of provisioning system in a Grid data-center environment, allowing for classic OS provisioning, virtual machine partitioning, embedded monitoring and clustered configuration management; at last a prototype of higly available and load balanced Grid services on a virtualized architecture. Most of these activities include advanced usage and customization of mostly open-source tools as Xen para-virtualizer, Nagios monitoring system, Cfengine and Puppet configuration management systems, SAN implementations through iSCSI and AoE (both software and hardware based).Speaker: Mr Federico Nebiolo (INFN)

Running EGEE services and worker nodes isung virtual machines 20mNew scientific communities, attracted by successful deployment of Grids by various scientific groups, bring new requirements on Grid middleware, such as fast turn-around for short jobs, access prioritisation, and need for various execution environment optimized to application specific requirements. We will argue that virtualized Grids, based on idea that different virtual worker nodes, running on and sharing physical cluster nodes, may help to implement some of these features. In this presentation, we will present our effort in virtualization of the national grid infrastructure in Czech Republic and we will describe a system called Magrathea, which we have developed to allow Grid job scheduling system to deal with several virtual machines (VMs) running concurrently on a single computer. With help of two HEP and EGEE related deployment scenarios (service consolidation of EGEE services and sharing of worker nodes between EGEE and MetaCentre grids) we will demonstrate how virtual machines can be already used to fullfill some of new requirements.Speaker: Jan Svec (CESNET)

Virtualisation usage at CERN 20mOne may say that virtualisation techniques were present since some years. But this year it seems to be that virtualisation surged ahead of "Web 2.0" as the buzziest of buzzwords in the sector of information technology. In the first half of March 2007 the FIO group launched its virtualisation project. The main object is to use the availability of cheaper and more powerful machines to consolidate low utilisation services. Besides this, there is an increasing demand for test and development machines, which are usually not heavily loaded and thus could be easily virtualised. Half a year later I'd like to share experiences the project team made during the integration of a Xen based virtual machine environment into the existing infrastructures of CERNs Computing Centre. This covers issues regarding configuration, installation, monitoring, managing and modelling of the virtual machine environment. Since FIO is not the only group using virtualisation technologies I will also report about two other use cases. One is the Certification and Test of the gLite middleware within the EGEE project. The other one is the ETICS project which uses virtual machines in their build and test system.Speaker: Mr Jan Michael

End to End Data Integrity in the Enterprise 30mThe loss of a business critical application resulting from data corruption can be crippling and require huge efforts to repair. All businesses hope they have the know how to recover, yet no business wants an unplanned real-time test. Data corruption prevention, rather than recovery is key. Storage vendors, including those designing adapters, fabrics, and storage arrays design component-level data integrity into their products. Sometimes though, these techniques have not been sufficient and there is a trend to provide a mechanism for end to end data integrity. This talk discusses the nature of data corruption and what the storage industry is doing to provide open and ubiquitous end to end data integrity.Speaker: Jim Williams (Oracle Corp.)

CERN Alerter – RSS based system for the information broadcast to all CERN offices 30mNearly every large organization uses a tool to broadcast messages and information across the internal campus (messages like alerts announcing interruption in services or just information about upcoming events). These tools typically allow administrators (operators) to send "targeted" messages which are sent only to specific groups of users or computers, e/g only those located in a specified building or connected to a particular computing service. CERN has a long history of such tools. The last one - NICE Alerter used on all Windows-based computers had to be phased out as a consequence of phasing out NNTP at CERN. The new solution continues to provide the service based on cross-platform technologies, hence minimizing custom developments and relying on commercial software as much as possible. The new system, called CERN Alerter, is based on RSS (Really Simple Syndication) for the transport protocol and uses Microsoft SharePoint as the backend for database and posting interface.
