Help to choose correct raid controller

Hi,

recently I purchased used DELL T310 Poweredge server (generation 11). Now I need to get some RAID controlled for it.

Here are some requirements:

- Win 2012 support

- RAID5 support

- Compatibility with server

- Reasonable price.

I tried calling Dell support and they told me to use H200, which does not meet first 3 requirements. So need some help from community now.
