I am planning to install CentOS 6.4 on Dell R720 which has hardware raid card and 6 hard disk slots available.
I have planned with the below set up :-
*2 Hard disks configured in RAID 1 for installing OS
*4 Hard disks configured in RAID 10 for data drive.*
Please suggest and recommend if the above approach is correct and let me know if i am missing anything which is crucial to set up a production server. This server will host MySQL DB server.
