how is this different from red hat?
Red hat seems to offer the same sort of thing: https://www.redhat.com/en/technologies/storage/ceph
Given Red hat bought the company that created Ceph (https://www.redhat.com/en/about/press-releases/red-hat-acquire-inktank-provider-ceph), article is not clear why someone would want to choose this platform over another based on Ceph.
But I guess the article is not alone, looking at the SuSE Ceph site - it makes no attempt to say how or why they may be better than Red hat (or any other Ceph-based solution), it only compares itself to non Ceph.
Obviously I'd expect much of the underlying core code to be the same across systems but they can differentiate with their pricing and their monitoring/management tools(vs other Ceph solutions), if they do differentiate they don't do a good job at communicating that.
Of course if you are already a SuSE Linux customer than it would make sense to use them if you were interested in a Ceph storage option.
(Not a Red hat nor SuSE customer, never used Ceph))
I was a brief SuSE customer I guess you could say maybe 13 to 15 years ago, bought several versions of their desktop linux distro at the time. It was pretty slick, though my sister used it more than me I kept to Debian, until at some point switching to Ubuntu on desktop/laptop(only) and now Mint(MATE). I remember one time looking at my sister's computer with SuSE and she had installed Yahoo messenger on it, the windows version. I was shocked that wine worked so well she could do it herself without asking me(she knew very little about computers).
