The STAR-CSCS FTS channel hosted by FZK has now been extended to also allow transfers to the new SRM endpoint. The SRM transfer quality looks good, though the actual rate is not overwhelming. Only T1_ASGC transfers have problems and ther errors uniformly seem to indicate a problem on the T1 side. Statistics for the last 12 hours: <verbatim> SITE STATISTICS: ================== first entry: 2007-04-02 08:29:00 last entry: 2007-04-02 12:02:17 site: T1_FZK_Buffer (OK: 54 / Err: 0) succ. rate: 100.0 % total: 133.2 GB avg. rate: 6.4 MB/s = 53.8 Mb/s site: T1_RAL_Buffer (OK: 1 / Err: 0) succ. rate: 100.0 % total: 2.6 GB avg. rate: 0.8 MB/s = 7.0 Mb/s site: T1_ASGC_Buffer (OK: 0 / Err: 42) succ. rate: 0.0 % total: 0.0 GB site: T1_FNAL_Buffer (OK: 9 / Err: 0) succ. rate: 100.0 % total: 24.6 GB avg. rate: 1.3 MB/s = 10.8 Mb/s *** ERRORS from T1_ASGC_Buffer:*** 42 Failed SRM get on httpg://castorsc.grid.sinica.edu.tw:8443/srm/managerv1 ;id=[id]call. Error is specified file(s) does not exist </verbatim> I can sometimes see that there are big transfers between the dCache pool nodes. Either a door on one node is actually saving a file on the other node or it is some kind of redistribution (probably the first, I guess). This waste of bandwidth is not optimal and should be studied. %ICON{arrowleft}% Go to [[CMSSiteLog5][previous page]] / [[CMSSiteLog7][next page]] of CMS site log %M% -- Main.DerekFeichtinger - 02 Apr 2007
