Older FCX 648-S - troubleshooting throughput issues, + firmware upgrade
My office has an older Brocade FCX 648-S from which I'm trying to get more throughput. It's configured as a layer-3 switch with several VLANs. I've only been able to get about 150 Mbit sustained throughput from any single client connection.
So far I've double-checked port speed/duplex settings, known-good Ethernet cables, etc. I tried disabling flow control (no effect). I'm not really sure what else to try. I'm fairly knowledgeable on networking in general, but am admittedly not a network engineer or a router/switch configuration expert.
Any thoughts on how to diagnose where the problem is? Or, am I really just dealing with a function of old hardware?
The switch is currently running software version 7.0.01b. I see there is an 08.0.30t version on the Ruckus site. Should I try upgrading, and if so, is it safe to jump straight to the latest version?
