Oracle/Sun have shut down the thor line of file servers. SLAC needs to find an alternative set of vendors. Here we investigate options and gather data.

Other Labs

  • FNAL (12/12/10 source: Steve Wolbers; contact Richard Dubois)
    • Nexsan Satabeast recently
    • they are out to bid for a big CMS order and will share the RFP with us in Jan/Feb
  • CCIN2P3 (12/13/10 source: Dominique Boutigny; contact Richard Mount)
    • The solution that we have retained is a DELL Server R510 + 2
      extensions MD1200 (54 TB of usable space). The cost is ~0.3 ? / GB.
      The performances have been measured by our storage experts and are
      suitable for dCache but may not be enough for intensive xrootd access.
      I will ask Benoit to send you the quantitative results of the tests.
