The impact of not following the 'best practice' of putting my vMotion and Management traffic on a dedicated VLAN seems to have finally showed itself.
I've been on a persistent VM for 3+ years now. It's been great, except for occasionally I'd get 'Session Lost!' on my zero client. It didn't happen often enough to concern me ... until it did. It was around this time that we started noticing several of us were being kicked off simultaneously. Those of us on 100Mb had issues, but not those of us on 1000Mb.
Thanks to having Riverbed Cascade we could see that the smaller ports were being flooded and overwhelmed by broadcasts from a vMotion port. Two days after establishing the VLAN and I have seen zero sessions lost.
