Technical details about network, disk, monitoring and so on will be given. CSC provides for HIP some 100TB of disk storage for CMS-T2 and about 70 TB of disks with a tape-backend for the NDGF-Alice T1-centre. Internal and external network traffic is split on the network-level. The CE and the middleware...

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...

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.

CERN's AFS installation serves between 1 and 2 billion

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.

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,...

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...

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...
