Goal

StorageProfiles ease the burden of selecting the optimal PVC parameters (AccessMode and VolumeMode) for known CSI provisioners. As we encounter new provisioners we should determine the correct values and update our internal table in CDI so that our customers will get a better out of the box experience. Having a correct storage profile can also make VM provisioning order of magnitude faster (host copy vs. CSI clones). Several customer support cases have already arisen because the OCP certified provisioner had an empty or incorrect admin provided storage profile.

User Stories

• As a CNV administrator I want the storage I am using to work out of the box for creating optimal virtual machines with my existing storage.
• As a CNV administrator, I want cloning to use the optimal approach (csi-clone, csi-snapshot, host-assisted) automatically and this approach is visible in the storage profile associated with the provisioner.

Non-Requirements

• We will not have all the available storage equipment to test every new storage profile. We can collaborate with our storage partners to test on their systems.

Notes

Provisioners to add:

• Dell (PowerFlex / PowerScale / Unity / PowerStore)
• Hitachi (VSP)
• IBM Fusion (HCI/GPFS2, SDS/ODF, block arrays)
