All,
I have six Dell Equallogic SANs connected to two Cisco 3750X (Stacked) in a redundant fashion. I have enabled Jumbo Frames (9000) and I configured a Port-Channel connecting back to the Distribution Layer. Keep in mind, our SAN and Server traffic reside in the same VLAN. Our Virtualization Platform is Citrix / Xenserver. I'm currently seeing many Output Drops on the 3750X connecting the SANs. I believe the buffers are almost full. Any thoughts? Possible design recommendations?
