USCMS T2 Transfers

This twiki is intended to aggregate all necessary information for the current effort of improving inter-T2 PhEDEx transfers in the context of USCMS.

Changed:
<
<		It is known that the networks supported between the 7 sites are of high capacity and availability. However there seem to be some limitations to be addressed and tested at the level of CMS Transfer tools or configurations of these, that could improve the overall performance and at the end, make these systems perform better and deliver data faster between sites.

  The general picture on transfers over 20 Gbps and some of these configuration problems are mentioned in Samir's talk at the T2 meeting of 07/29.

 So far, the showstopper was the uplink bandwidth for most sites. Since July 2014 this is starting to change, this is to track the current state from different sites

  • MIT - 10 Gbps
Added:
>
>
  • Caltech - 100 Gbps
 
  • Nebraska - Could do more then 10 Gbps currently, will have 100 Gbps on the T2 soon.
  • Purdue - 100 Gbps. Running tests with FNAL.
  • Florida - 100 Gbps
Changed:
<
<
  • UCSD - 10 Gbps (Samir observed when running tests. To be confirmed by admins)
>
>
  • UCSD - 10 Gbps
 
  • SPRACE - 10 Gbps
Changed:
<
<
  • Wisconsin - 10 Gbps - Saturating from times to times. Would like to avoid tests for now.
>
>
  • Wisconsin - 10 Gbps
  • Vanderbilt - 10 Gbps
