I have an existing IBM Blade Center chassis with dual integrated Cisco MDS 9000 F/C switches connected to an EMC SAN. I recently added a Dell M1000E Chassis with dual integrated Brocade M5424 switches to my environment, and am preparing to connect those switches to the SAN. I'm a pure VMware shop, running ESXi 5.5/6.0 on the hosts in both the IBM chassis and the Dell Chassis.
I'm wondering if there is a best practice for making the connections from the new Dell chassis + switches to the SAN. Am I better off connecting the Brocade switches directly to the EMC SAN, or am I better off connecting the Brocade switches to the Cisco switches, and accessing the SAN via those switches. Or a combination of both?
The Cisco switches I have max out at 4Gbps, the Brocade at 8, and the EMC at 8, so it seems like a direct connection between the Brocade switches and the EMC SAN would be the most efficient, but there may be other considerations involved that I'm not aware of.
I'd value any input or observations that others may have on this, and would be happy to hear of any recommendations as to the best way to make these connections, ideally along with the rationale behind them.
Thanks in advance for your thoughts on this.
My apologies for the confusion. In this case, the storage device is an EMC VNX array, and not, as you pointed out, a SAN. I certainly should have been more clear about that in my original post. The IBM Chassis (via the Cisco switches) and the Dell Chassis (via the Brocade switches) both connect ot the EMC array.
