This chapter explains how to configure dCache in order to access it via the xrootd protocol, allowing xrootd-Clients like ROOT's TXNetfile and xrdcp to do file operations against a dCache instance in a transparent manner. The current implementation in dCache 1.7.0 is based on the most recent production version of the xrootd protocol (2.4.5).
