Sorry for the deep digging into the archives. I might be in a situation where I could get S4600 (with filestore initially but I would very much like them to support Bluestore without bursting into flames). To expand a Ceph cluster and test EPYC in our context we have ordered a server based on a Supermicro EPYC motherboard and SM863a SSDs. For reference : https://www.supermicro.nl/Aplus/motherboard/EPYC7000/H11DSU-iN.cfm Unfortunately I just learned that Supermicro found an incompatibility between this motherboard and SM863a SSDs (I don't have more information yet) and they proposed S4600 as an alternative. I immediately remembered that there were problems and asked for a delay/more information and dug out this old thread. Has anyone successfully used Ceph with S4600 ? If so could you share if you used filestore or bluestore, which firmware was used and approximately how much data was written on the most used SSDs ?
