A San Data Gateway is a device that converts SCSI protocols to fibre
protocols.

For example, if you have SCSI LTO1 tape drives in your 3583, and you want to
connect them to your SAN, they gotta go through the gateway to get to a SAN
switch.

So if your devices are fibre already, the SGD isn't involved.

(Maybe that helps, maybe not...)

I have a feeling that a SAN data gateway is an extra piece of equipment
that is used only for server-free data movement. A SAN switch is something
different, and is the normal way to connect drives to the server.

I hope 'normal' SAN failover works, because IBM are suggesting it for us in
their latest upgrade offer!
