Xserve RAID - Articles
University of Wisconsin deploys nearly 200TB of Xserve RAID storage

The University of Wisconsin - Madison has deployed 35 5.6TB Xserve RAID storage arrays in a single research installation as part of an ongoing scientific computing initiative.

The Grid Laboratory of Wisconsin (GLOW), a partnership between several research departments at the University of Wisconsin, have installed almost 200TB, or 200,000GB, of Xserve RAID arrays. As a comparison, 200TB of storage is enough to hold 2.75 years of high definition video, 25,000 full length DVD movies, 323,000 CDs, 20 printed collections of the Library of Congress, or over 1000 Wikipedias.

The GLOW storage installation is physically split between the departments of Computer Sciences and High Energy Physics. Each Xserve RAID is attached to a dedicated Linux node running Fedora Core via an Apple Fibre Channel PCI-X Card and is either directly accessed via various mechanisms, such as over the network via gigabit ethernet, or aggregated using tools such as dCache.

The storage is primarily used to act as a holding area for large amounts of data from experiments such as the Compact Muon Solenoid (CMS) and ATLAS experiments at the Large Hadron Collider at CERN.

Aside from the GLOW initiative, the university also has Xserve RAID storage systems in use in other areas as well.

Can someone tell me what the configuration is?
Is each Xserve RAID directly connected to a Windows or Linux machine (I do not see any Xserve) and serve as a head node to a cluster?
Any detail configuration would inspire us on how Xserve RAID products can be deployed.

Thanks
