Hello,
Your original information indicated the arrays had 10G iSCSI controllers. If this is true then you do not have the ability to add SAS connections between the two arrays. Connecting the two arrays via the backend SAS cables is not supported. This would be similar to connecting two Smart HBAs or Smart Array cards - chaos and not supported.
If you are changing the SAN fabric to SAS, then yes you can connect the two MSA 2040 SAS arrays via a switch. However, we do not have a SAS switch for DL380 G9 servers. We do have SAS switches for c7000 blade enclosures.
Hopefully this clears up any confusion.
Cheers,
Shawn
