Recently I will install a Fas 2750 in switchless mode without any disk shelf, the equipment does not include mini SAS cables for connection between controllers.
My question is about whether there will be any effect on failover performance, if a controller fails?
i think that you need to read more, you are always successfully
It should not have any effect on failover (performance). There will be one path to internal disks from each controller, but I find it acceptable given that all connections are via fixed backplane.
