<p class="MsoNormal"><span style="color:#1F497D">My understanding of this is the host OS (in this case VMWare) is bonded to certain ‘ports’, these ports are logical and can be mapped 1:1 to physical ports or to a bonded/teamed NIC. Given that most host/guest
OS share a 10GB connection, the slow point will be this logical connection at the host.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">Hmm re-reading perhaps not 100% clear.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Bond 2x 1gb ports = 2gb, the 2gb bonded port is mapped in Vmware to a guest OS, the guest OS should have 2GB network connectivity.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#002060">Hey all,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#002060"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#002060">Got an interesting debate with some server guys.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#002060"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#002060">It is my ‘theory’ (not backed up my technical facts) that a VM should be able to use more than 1Gig of throughput when a VM (VMware) is on a server that has a bonded NIC to a switch which ‘in Cisco talk’ is doing
a ether-channel/port channel to the server – the case in point is 2 cables together, but in theory should be able to go to 4 or more.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#002060"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#002060">The server guys are suggesting that a single VM can only go out one of the NIC ports and therefore only get to a maximum of 1Gb throughput.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#002060"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#002060">Is this true and is there any docs for either HP DL 380’s, VMware which would support either stance?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#002060"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#002060">Just trying to verify a theory, and since there would be a ton of people on this list which do VMware, NIC bonding into switching, I thought it would be a great place to ask.<o:p></o:p></span></p>
