Yes it will work. You need the 12G SAS HBA and a HD-SAS-Mini to HD-SAS cable. I have test it last week on a customer site. On the other hand... why not replacing a 10Y old storage?
So...yea. We have a MD3200 (which probably needs the firmware update still) and we're looking to move to vSphere 7. However, it's not on VMWare's HCL, and neither is the Dell SAS 6Gbps cards that we use to connect to the MD3200. ...and we tried anyways. Spoiler: It doesn't work. I belive the root is the removal of the linux-based drivers from vSphere. The host (Dell R630 & Dell R640) sees the SAS card, but won't/can't use it, and so the datastore isn't recognized. So, we're stuck at vSphere 6.7 until further notice. Has anyone else tried vSphere 7 with the MD3200 and had any success?
