Re: Kafka disk recommendation for production cluster
I meant because there is no actual Raid Controller for running Raid on cloud, it is basically Software Based Raid [1].

Re: Kafka disk recommendation for production cluster
Dong Lin's KIP - https://cwiki.apache.org/confluence/display/KAFKA/KIP-112%3A+Handle+disk+failure+for+JBOD Should give you some ideas.

Kafka disk recommendation for production cluster
Hi All, I was wondering what the disk recommendation is for Kafka cluster? Is it acceptable to use RAID0 in the case that replication is 3? We are running on a cloud infrastructure and disk failure is addressed at another level, so the chance of single disk failure would be very low. Besides, our version of Kafka does not fully support JBOD as even a single disk failure can stop a Kafka broker, so we will not get the actual benefit of using JBOD anyway. However, I am not quite sure how software raid acts in this situation as there is no option to use HW Raid on cloud. Regards, Ali
