Raid question

[Romeo Theriault]

Hello, We are in the process of purchasing a new two new servers. One  
of these servers is a database server and needs to have a Raid 1 for  
the OS and Applications storage and a Raid 10 at least 146 gb for the  
Database storage. My question is, Do I need to by a server with two  
raid controllers? One for each of the different arrays or can one  
card do this?

Thank you for any information on this.
