I have two 3750G-24T switches sitting between a couple of servers and a Lefthand iSCSI SAN. Each server and all of the SAN modules have two NICs (one connected to each switch). Is it better to have the switches stacked or should I put them in a cluster? Or both stack and cluster? Or is there a better way to setup the switches for an iSCSI SAN? Which method provides for a better failover?
Right now the switches are in a stack. Over the weekend, one of the switches had a problem and all of my servers loss access to the SAN. Is there some sort of delay when a stacked switch fails? I had to reboot both switches to regain connectivity to the SAN.
Thanks for any and all replies.
