Deducting RAID loss and system disks brings this down to 18TB of usable space for the experiments and management VOs. CMS may use on the order of 22 TB during CSA07. Here follow some typical usage plots of the system during the last two weeks: Most of the wide area transfers are CMS !PhEDEx transfers. We got commissioned for downloading from FZK, FNAL and for uploading to FZK. Some of the CMS jobs show high transfer rates from the storage elements (using dcap). ---++ 1. 10. 2007 commissioning of routes from FZK, FNAL, RAL and to FZK Got transfer commissioning from RAL. !IN2P3 had a problem with their FTS server over the weekend. <verbatim> SITE STATISTICS: ================== first entry: 2007-09-30 21:18:08 last entry: 2007-10-01 09:12:56 site: T1_FNAL_Buffer (OK: 206 Err: 22 Exp/Canceled: 79) succ. rate: 90.4 % total: 566.1 GB site: T1_FZK_Buffer (OK: 257 Err: 35 Exp/Canceled: 0) succ. rate: 88.0 % total: 635.0 GB site: T1_IN2P3_Buffer (OK: 63 Err: 168 Exp/Canceled: 81) succ. rate: 27.3 % total: 155.8 GB site: T1_RAL_Buffer (OK: 248 Err: 0 Exp/Canceled: 97) succ. rate: 100.0 % total: 690.5 GB TOTAL SUMMARY: ================== first entry: 2007-09-30 21:18:08 last entry: 2007-10-01 09:12:56 total transferred: 1906.8 GB in 11.9 hours avg. total rate: 45.5 MB/s = 364.2 Mb/s = 3841.3 GB/day </verbatim> !IN2P3 problems seemingly fixed.
