Hi, my team did some benchmarks in the past to answer this question. I don't have results at hand, but conclusion was that it depends on how many disks/OSDs you have in a single host: above 9 there was more benefit from more cores than GHz (6-core 3.5GHz vs 10-core 2.4GHz AFAIR). -- Tomasz Kuzemko tomasz.kuzemko@xxxxxxxxxxxx On 20.01.2016 10:01, Götz Reinicke - IT Koordinator wrote: > Hi folks, > > we plan to use more ssd OSDs in our first cluster layout instead of SAS > osds.
