I have a storage device that needs to receive connections from a VM in vmware.Since the communication is layer 2 I reached a problem where vlan pools overlap between the EPGs since the physical domains are different. Which would be the best solution ...

I was just reading a previous post of yours: On the 3750 series, when dealing with bursty traffic, I've had great success by tuning the hardware buffers. Basically, rather than using the defaults, which reserve 50% of your buffer space to interface...
