procedure to set service pack 10.50.1702 for MS SQL server 2008 R2 on an ECC system running(of course on windows server 2008 standard).

Hello

I wander what is (simple saying) procedure to set service pack 10.50.1702 for MS SQL server 2008 R2 on an ECC system running(of course on windows server 2008 standard).

Also I wander about difference on MS cluster solution(same but productive system)

Thank you in advance
