RAM requirements for QuarkDB/EOS

Hello,

Are there any stringent RAM requirements for EOS (MGM/FST) and QuarkDB? This is for our pre-prod cluster.

Thanks,

George

Hi George,

The correct answer to this question is that it depends on how many entries (files/directories) your instance will have. This applies for the QuarkDB machines. For the MGM since it acts more like a cache for namespace entries, the more the better, but you can definitely work with anything above 32GB. For the FSTs there are no special requirements. You can check the following table for a rough estimate of RAM requirements:
