BeStMan is a full implementation of SRM v2.2, developed by Lawrence Berkeley National Laboratory, for disk based storagesystems and mass storage systems such as HPSS. End users may have their own personal BeStMan that manages and provides an SRM interface to their local disks or storage systems. It works on top of existing disk-based unix file system, and has been reported so far to work on file systems such as NFS, PVFS, AFS, GFS, GPFS, PNFS, and Lustre. It also works with any existing file transfer service, such as gsiftp, http, https and ftp. It requires the minimal administrative efforts on the deployment and maintenance.
Bestman also has a "gateway mode" that can be used to manage storage on a backend file system. It works particularly well with XRootd. Documentation on setting up Bestman's gateway mode, with or without XRootd, is below.
