Powervault Modular Disk Storage Manager constantly loosing connection to MD3220

Have a MD3220 with two SAS controllers. Both controllers assigned static IP's (172.16.10.x). Have a PE R610 server loaded with win 2012 R2 and have MDSM loaded on there and its connected to same network as the SAN. Every few hours the software loses connection to the SAN and i cant figure out why.. I have to right click on the SAN in the software and remove it.. then do a new discovery and it adds it back in. Once i do this it shows optimal for a few hours until it loses connection and says unresponsive again.. What gives?
