We're involved in a DC infrastructure upgrade for a customer with several HP blade chassis, which all have Cisco 3020 switches.
In trying to figure out the new Nexus 5K/2K (FEX) design to upgrade them to Gigabit server access, they're questioning what the right replacement is for these TOR 3020s. Specifically:
Do the B22 FEX modules replace the 3020’s one for one, or are they advanced and provide the 4 ethernet connections for each blade with just one module?
Any advice or design ref/guidance for this question would be helpful, and thank you.
