External approach

IBM Storage Fusion Data Foundation exposes the IBM Storage Ceph services running outside of the OpenShift Container Platform cluster as storage classes.

The external approach is best used when,

• Storage requirements are significant (600+ storage devices).
• Multiple OpenShift Container Platform clusters need to consume storage services from a common external cluster.
• Another team, Site Reliability Engineering (SRE), storage, and so on, needs to manage the external cluster providing storage services. Possibly pre-existing.
