You should look at a 60 bay 4U chassis like a Cisco UCS C3260. We run 4 systems at 56x6tB with dual E5-2660 v2 and 256gb ram. Performance is excellent. I would recommend a cache tier for sure if your data is busy for reads.

It will be used for storing online videos. We do not expect outstanding write performace, something like 200-300MB/s of sequental write will be quite enough, but data safety is very important. What are the most popular hardware and software recomendations? 1) What EC profile is best to use? What values of K/M do you recommend? 2) Do I need to use Cache Tier for RadosGW or it is only needed for RBD? Is it still an overall good practice to use Cache Tier for RadosGW? 3) What hardware is recommended for EC? I assume higher-clocked CPUs are needed? What about RAM? 4) What SSDs for Ceph journals are the best? Thanks a lot!
