| It is not just a question of which SSD. It's the combination of distribution (kernel version), disk controller and firmware, SSD revision and firmware. There are several ways to select hardware 1) the most traditional way where you build your BoM on a single vendor - so you buy servers including SSDs and HBAs as a single unit and then scream at the vendor when it doesn't work. I had a good experience with vendors in this scenario. 2) based on Hardware Compatibility Lists - usually means you can't use tha latest hardware. For example LSI doesn't list most SSDs as compatible, or they only list really old firmware versions. Unusable, nobody will really help you. 3) You get a sample and test it, and you hope you will get the same hardware when you order in bulk later. We went this route and got nothing but trouble when Kingston changed their SSDs completely without changing their PN. Would we recommend s3700/3710 for Ceph? Absolutely. But there are still people who have trouble with them in combination with LSI controllers. Can we recommend Samsung 845 DC PRO then? I can say it worked nicely with my hardware. But surely some people had trouble with it. I "vote" against creating such a list because of all those reasons, it could get someone in trouble. Jan
