we want to design production kafka cluster with 7 kafka machines , on RHEL OS
kafka version should be - 2.7
usually we are installing the kafka machine/s disks as RAID 10
( as confluent recommended )
but as maybe some of you know Kafka disks, can configured as Jbod ( its mean each single disk will defined in logs dir
, as opposite to RAID10
that all disks are actually are in RAID and represented as one disk
for example RAID10
will shown from RHEL OS as one disk - sdb
while Jbof will shown from OS as
sdb
sdc
sdd
sde
.
.
.
the big Question when dealing with Kafka disks, is what is better? , especially from point of view of Kafka performance side
