Change in federating direct dCache• Up to now directly federating dCache xrootd doors

required a “helper” with two pairs of xrootd/cmsd services• A redirector plugin developed

– Enables native dCache upstream redirection– Delivered with dCache N2N plugin (same rpm)

• Simplifies configuration, improves redundancy• Documented in TWiki • A very nice document, detailing dCache in federation

written by Andy– http://www.slac.stanford.edu/~abh/Fed-dCache/fed_dCache.pdf

• MWT2, AGLT2, SFU already using the new method

as expected– FT FAX direct rc_test : Simple histogram making 17.5

.0, Local DS,transfertype=fax • Waiting for a production pilot to re-start

scheduling jobs to overflow (Tuesday)o After running it for a week we will test how well limiting

bandwidth works (wanlimitsource, wanlimitsink).
