I am upgrading Unity 4.2 to Unity Connection 7.0. Currently, we have Exchange 2003 severs with HBAs for SAN backup. If we reuse the MCS-7845, can I just put HBAs in them to support SAN backup???
Unity Connection did not follow the traditional Unity design for virtual machine suppot. Unity Connection does not support virtualization at all until 8.0(2). At that point it is only supported on a very specific list of Cisco hardware.
