Hi, It's loooking likely that dCache is going to be widely deployed certainly in the UK and probably across LCG and I was thinking about how this could be integrated with the xrootd deployment we have for use by babar. I can think of two (probably) fairly simple things that would be useful. 1) Enabling the dcap protocol in the KanAccess.cfg file. As far as I know the dCache protocol dcap is built into root in the same way that the xrootd protocol now is so if we can build file urls that start with dcap:// or dcache:// we could access files directly from dcache. 2) Adding an xrootd door to dCache. This is obviously more complex but I guess it would just mean replacing the ofs layer with something that speaks to dCache rather than the filesystem. This would mean you could get all the benefits of the xrootd protocol, scaling, redirection, load balancing, fault tolerance, proxies, etc. with a dCache backend. I know the second one has been discussed but are there any plans to implement it? It would be particularly useful to us here at RAL (and, I suspect, simmilarly the other European tier As) since we are deloying large dCache installation for the LHC experiments which BaBar couold then share.
