<p class="MsoNormal"><span style="color:#002060">Hey all,</span></p>
<p class="MsoNormal"><span style="color:#002060"> </span></p>
<p class="MsoNormal"><span style="color:#002060">Got an interesting debate with
some server guys.</span></p>
<p class="MsoNormal"><span style="color:#002060"> </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.</span></p>
<p class="MsoNormal"><span style="color:#002060"> </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.</span></p>
<p class="MsoNormal"><span style="color:#002060"> </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?</span></p>
<p class="MsoNormal"><span style="color:#002060"> </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.</span></p>
