Bluearc structure¶

The Bluearc support heararchy is as follows :

• Cluster - array of redundant servers ( FERMI-BLUE, ITNAS-A, RHEA )
  • Head - server within the cluster, with failover)
    • Span - the raid array on which files reside
      • EVS - path used to export the file systems
        • FS - file system within the SPAN
          • vivol - directory that is exported

The file systems we are discussing on on the FERMI-BLUE Cluster.
evsnames include

• blue2
• blue3
• cdf-nas-0
• d0-nas-0
• des-nas-0
• if-nas-0
• sci-win-nas-0

The APP areas are exported under blue2, usually served by head 2.
The DATA areas are exported under blue3, usually served by head 1.
