We have this summer flattened our "2003 file server". It is a physical server connected to an Dell MD3000 Array. It now has Server 2008 R2 installed and currently all unchanged out of the box.

I was wondering if there are any pointers or tips that are advised to improve performance/stability etc on R2 connected to an array?
We are not currently having any issues, but Im sure I have read over the last few years some threads but never taken them in as we were still on 2003.

Thanks in advance.
