File path in unified file and Swift Object access

One of the key advantages of unified file and Swift Object access is the placement and naming of Swift Objects when they are stored on the file system.

Important:
  • CES Swift Object protocol feature is not supported from IBM Storage Scale 5.2.0 onwards.
  • IBM Storage Scale 5.1.8 is the last release that has CES Swift Object protocol.
  • IBM Storage Scale 5.2.0 will tolerate the update of a CES node from IBM Storage Scale 5.1.8.
    • Tolerate means:
      • The CES node will be updated to 5.2.0.
      • Swift Object support will not be updated as part of the 5.2.0 update.
      • You may continue to use the version of Swift Object protocol that was provided in IBM Storage Scale 5.1.8 on the CES 5.2.0 node.
      • IBM will provide usage and known defect support for the version of Swift Object that was provided in IBM Storage Scale 5.1.8 until you migrate to a supported object solution that IBM Storage Scale provides.
      • CES Swift Object is replaced with IBM Storage Scale S3. For more details, refer S3 support overview.
      • For more information about Swift Object in IBM Storage Scale, refer to the IBM Storage Scale 5.2.0 documentation.
  • Contact IBM for further details and migration planning.

Unified file and Swift Object access stores Swift Objects following the same path hierarchy as the Swift Object's URL. In contrast, the default Swift Object implementation stores the Swift Object following the mapping given by the ring, and its final file path cannot be determined by the user easily.

A Swift Object with the following URL is stored by the two systems as follows:

  • Swift Object URL: https://swift.example.com/v1/acct/cont/obj

  • Path in default Swift Object implementation: /ibm/gpfs0/object_fileset/o/z1device108/objects/7551/125/75fc66179f12dc513580a239e92c3125/75fc66179f12dc513580a239e92c3125.data

  • Path in unified file and Swift Object access: /ibm/gpfs0/obj_sofpolicy1/s69931509221z1device1/AUTH_763476384728498323747/cont/obj

It is assumed that the Swift Object is configured over the /ibm/gpfs0 file system with the default Swift Object on the object_fileset fileset and the unified file and Swift Object access data is located under the obj_sofpolicy1 fileset. s69931509221z1device1 is auto-generated based on the swift ring parameters and AUTH_763476384728498323747 is auto-generated based on the account ID from keystone.

Attention: Do not unlink Swift Object filesets - including the unified file and Swift Object access enabled filesets.
