Dear All;
I found the solution, and though of sharing it with you.
SAP Note 1944415 "Configuration Guide for Hardware Platforms of SUSE Linux Enterprise Server" explains each server model with the required RAID that needs to be configured on.
The document which I used earlier was released earlier in 2013, but SAP Note 1944415 is released in JAN 2014.
In my case the server I am using is Dell, and SAP recommends using RAID1/ RAID5 which is more secure and safer than RAID0.
In RAID1 and RAID 5 there is redundancy available, and this will save the customer business from any data loose.
