I am tempted to use MinIO, but I've read mixed reviews about it and Ceph seems...

    Hi Everyone, One of my major clients is considering PVE but I've run into the same snag as earlier this year. The organization has several HPE Nimble SANs and they aren't going away as far as I can tell. HPE Nimble is block storage only, so iSCSI is basically the one and only solution...
