All - I have been following this thread for a bit, and am happy to see how involved, capable, and collaborative that this ceph-users community seems to be. It appears there is a fairly strong amount of domain knowledge around the hardware used by many Ceph deployments, with a lot of "thumbs up" and "thumbs down" sort of experience based on bugs, problems, issues, configuration landmines to avoid, etc... Is there somewhere that community experience with hardware like this is being tracked? Not necessarily a full blown HWCL (hardware compability list), but maybe a more cohesive list of controllers, SSD/Spinning disks, and the community lessons learned (like when to or not to use TRIM, silent corruption, etc...)??? It seems like this is all extremely valuable information as "new operators" like my self come in to the picture... Yes, one can mine the email archives ...
