We try to set up FAS2040A for VMWare environment with FCP protocol. One FC port on each controller is used for disk shelfs. We have also 2 brocade FC switches.
We have only one FC port on controller left. We can only connect one filer to the first switch and other filer to the second switch. With that topology we can not achieve full redundancy if one switch fails.
No, that’s incorrect. If one switch fails, LUN access is retained via partner connection. This is the same as was on FAS270C. You have to set cfmode to single_image, but this is effectively the only cfmode supported today.
And, BTW, FAS270C dual_fabric was never active/active ☺
