ambari cluster + how to defined the RAID on masters machine partitions

[#1]

we want to define the RAID configuration on our masters machines we have 3 masters machines ( while ambari-server installed on master02 machine )

each master machine have 3 partitions one partition for hadoop one partition for zookeeper one partition for hdfs as the following:

/dev/sdb 393G  252M 392G   1% /hadoop 
/dev/sdc 393G  298M 392G   1% /BD/hadoop/zookeeper 
/dev/sdd 908G  257M 9008G  1% /BD/hadoop/hdfs

for now we configured the RAID as the following:

raid 0 for /dev/sdb and /dev/sdc

raid 1+0 (raid10) for /dev/sdd

dose the raid configuration that we configured for the partitions on the masters machine is OK ,

or maybe need to configured raid10 also for the other partitions?
