Hi, This may be off-topic for this list but anyway - I am asking people who dealt with both xrootd and other storage systems (dCache, DPM, etc) to comment on your expirience with those other systems, as compared to xrootd. I am specifically interested in operational expirience, plus existance of the features provided by xrootd. Some of topics of interest: - load balancing - fault tolerance - setting up transparent MSS access - data transfer tools - feedback for bugs and feature requests - known limitation +anything else you want to say. Is there anyone using xrootd for LCH experiments (other than Alice)? Thanks in advance, Artem.
