Hello In-Nam,

Please be aware that NFS is no longer supported by Data Hub because it has certain limitations that prevent the distributed log (dlog) to function properly as per SAP Note 2712050 – SAP Data Hub 2.3 installation fails during validation step “vora-cluster”.

Best regards

Frank

Hello In-Nam,

No, SAP Data Hub 2.4 persistent storage does not have to be cloud based. I am for example using ceph on premise.
