We present our experience in setting up an xrootd storage cluster at CC-IN2P3 - a LCG Tier-1 computing Center. The solution consists of xrootd storage cluster made of NAS boxes and includes an interface to dCache/SRM, and Mass Storage System. The feature of this system is integration of PROOF for facilitation of analysis. The setup allows to take advantage of ease of administrative burden, scalability and performance of xrootd, reduction of total cost due to integration of PROOF, while satisfying requirements for SRM interface, strong authentication for transfer and complex data management applied by LCG to site's storage. The same setup can be used at large or small HEP computing centers as analysis facility and data access systems. Variations of this setup for smaller sites are also considered. Feedback from experiments on this setup is also reported.
