Hello, I was wondering whether it would be feasible to manage existing FC-SAN storage with ceph. Now this may sound somewhat weird, so let me explain: as it turns out you can't actually trust SAN boxes with RAID-6 devices to actually hold your data, so I thought that maybe you could - set the existing SAN boxes to export its storage in JBOD chunks - use some blades (they have 64gigs of RAM each) to mount those SAN FC exports - use those mounts as OSDs - and store the data on 3 OSDs (each one being a different SAN box) to get HA back Or maybe it would be better to set up the SAN boxes to export RAID-5 devices and only have the data reside on 2 OSDs then? Is there anything particularly problematic with this idea? Since the SANs actually have SAS disks, I thought that one might get away with having no SSD in the blade for an intent log...?
