Hi, Cores > Frequency If you think about recovery / scrubbing tasks its better when a cpu core can be assigned to do this. Compared to a situation where the same cpu core needs to recovery/scrub and still deliver the productive content at the same time. The more you can create a situation where an osd has its "own" cpu core, the better it is. Modern CPU's are anyway so fast, that even SSDs cant run the CPU's to their limit. -- Mit freundlichen Gruessen / Best regards Oliver Dzombic IP-Interactive mailto:info@xxxxxxxxxxxxxxxxx Anschrift: IP Interactive UG ( haftungsbeschraenkt ) Zum Sonnenberg 1-3 63571 Gelnhausen HRB 93402 beim Amtsgericht Hanau Geschäftsführung: Oliver Dzombic Steuer Nr.: 35 236 3622 1 UST ID: DE274086107 Am 20.01.2016 um 10:01 schrieb Götz Reinicke - IT Koordinator: > Hi folks, > > we plan to use more ssd OSDs in our first cluster layout instead of SAS > osds.
