You can't have two different RAID levels in the same array, but you can have multiple arrays on the same controller (which is probably what you want).  This is a fairly sophisticated controller and should be able to maintain two arrays with no problem: http://www.lsilogic.com/files/docs/marketing_docs/storage_stand_prod/raid/mr_3202E_ss.pdf

anandjayaraj,

If I was able to help you, may I know why I received a C grade?  I know that this is your first question, but see http://www.experts-exchange.com/help.jsp#hi73 for grading guidelines.

Dear Callandor,
It was an error of not having gone  through the grading guidelines.
Thank you once again for your answer.
