ZFS Performance Focused Parameters

February 20, 2018

We’ve recently gotten some significantly larger storage systems and after running some 50T pools with basically all the defaults it felt like time to dig into what common options are used to chase performance. The intended use for these systems is ultimately CIFS/NFS targets for scientists who are running simulations that generate small (1M) to large (100G) files. I’m not being rigorous and offering any benchmarks, just digging into documented performance parameters and explaining the rational. ...
