Configuring SFS Turbo and OBS Interworking

SFS Turbo HPC file systems can access objects stored in OBS buckets seamlessly. You can specify an SFS Turbo interworking directory and associate it with an OBS bucket.

  1. Log in to the SFS console. In the left navigation pane, choose SFS Turbo > File Systems.
  2. In the file system list, click the name of the HPC file system created in Creating Resources to go to its details page.
  3. Click the Storage Backends tab and then click Add OBS Bucket.
