How to order data sets for the PSI Tier-3

Please follow the instructions for the ordering of data sets to the CSCS Tier-2, but use T3_CH_PSI as the destination site.

To see the currently stored data sets for the Tier-3 and the Swiss Tier-2 you can look at these PhEDEx pages.

Note, that we do only have channels from CSCS and FZK. Currently PhEDEx will only download data sets which it can get via such a direct link. So, if a set is not already located at one of these directly linked centers, it is necessary to order the data to one of them as well (order it to both T2_CH_CSCS and T3_CH_PSI. We cannot guarantee that FZK would carry out a request to stage the data on their storage). The request page will show you all locations of copies of the data set you want to order.

Note: Even though PhEDEx had the capability to transfer data through multiple hops, this has been currently deactivated, since it causes problems with the management of the storage space of the centers that are used as caches.
