Description
We report about the tests performed in the INFN Pisa Computing Centre with some of
the latest generation storage devices. Fibre Channel and NAS solutions have been
tested in a realistic enviroment, both participating in Worldwide CMS's Service
Challenges, and simulating analysis patterns with more than 500 jobs accessing
concurrently]data files. Both usage pattern have evidentiated the ability to use
today's storage links at 10 Gbit/s, allowing a steady transfer rate exceeding what a
single Gbit/s interface cannot guarantee when the number of concurrent users increase
over a few hundred nodes.
