bestman 2
BeStMan-2
  • Berkeley Storage Manager (BeStMan) 2
    • Retains all functionalities of the previous BeStMan
      • SRM v2.2 implementation – interoperable and compatible to other implementations
      • Works on existing storages with posix-compatible file systems
        • Adaptable to special file systems and storages with customized plug-in
      • Supports multiple storage partitions
        • Supports pre-defined static space tokens
      • Easy adaptability and integration to special project environments
      • Supports multiple transfer protocols
        • Supports load balancing for multiple transfer servers
      • Supports grid-mapfile or GUMS server
      • Supports Gateway Mode for faster performance
        • Scales well with some file systems and storages, such as Xrootd and Hadoop
    • Improvements from the previous BeStMan
      • Jetty based web server container
        • Better performance in http connection handling through configurations
      • Updated dependency libraries
      • New packaging but the same setup process as the previous package
a few benefits on adopting bestman
A few benefits on adopting BeStMan
  • User access restriction to certain directory paths through configuration
  • User access control to files by owners/creators only
  • Site-specific customization on the load-balancing mechanism for transfer servers through plug-in
  • Site-specific customization on the file system i/o mechanism for special file system or storage system through plug-in
  • Plug-in extension for external archival storage systems
  • Works with other SRM v2.2 server and client implementations
  • Easy deployment and simple maintenance
    • Dynamic deployment and personal SRM
      • If the target host does not have an SRM, BeStMan can be downloaded, installed, configured, and started with a few commands (or a script) by the end-user for his/her own BeStMan.
