      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Thanks Robert. I am aware of the process for setting up pass through, but there has been a lot of discussion about it being broken in 5.1.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I was wondering if it had actually been fixed by VMware yet?&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hello,&lt;/P&gt;&lt;P&gt;The server itself is a Cisco UCSC-C240-M3S2. The device I am trying to passthrough is a onboard USB2.0 controller. Perhaps that could be the problem...&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;On Tuesday I am planning on upgrading a IBM x3100 M4 server running ESXi 5.0.0 Update 2. Installed in the server is a D-Link PCI Express card that is currently working successfully in PCI Passthrough mode to one of the VMs.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I am unsure at this stage whether to upgrade to ESXi 5.0.0 Update 3 or to 5.1.0 Update 2. Considering the issues I'm having with 5.1.x Update x I'm tempted to just upgrade to ESXi 5.0.0 Update 3.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;The only reason I am considering updating to 5.1.0 Update 2 is because another host in a different branch office is running that version so would like to keep it the same.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Guess what I can do is upgrade the host to 5.1.0 Update to, test the pci passthrough of the dlink USB3.0, if it fails roll back the host to 5.0.0 Update 3. (as long as I make sure not to upgrade the hardware of the VM's...)&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hello,&lt;/P&gt;&lt;P&gt;The IBM Model is a 2582E4M, Intel Xeon &lt;SPAN style="font-size: 10pt;"&gt;E3-1270v2 and Intel C202 Chipset.&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&lt;SPAN style="font-size: 10pt;"&gt;&lt;BR /&gt;&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&lt;SPAN style="font-size: 10pt;"&gt;That compatibility guide is odd. It basically says no IBM Servers support VM Direct Path IO. I've got 10+ servers running a USB PCI device in passthrough mode and it works OK. I guess the compatibility guide only lists 'approved features'. The fact I have it working on so many servers is probably just luck. &lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&lt;SPAN style="font-size: 10pt;"&gt;&lt;BR /&gt;&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&lt;SPAN style="font-size: 10pt;"&gt;I still might try updating it to 5.1.0 U2 on Tuesday and see how it goes. Since it's not officially supported I guess there is no way of knowing apart from actually doing it!&lt;BR /&gt;&lt;/SPAN&gt;&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hello Peter,&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Yes HCL outputs may appear odd in some cases but I think they aren't...in your case HCL just says that IBM as a vendor doesn't TEST&amp;nbsp; its servers for "VM Direct Path IO" this&amp;nbsp; &lt;SPAN style="text-decoration: underline;"&gt;is always a vendor initiative&lt;/SPAN&gt; within TAP program.&lt;/P&gt;&lt;P&gt;At the end of this process each vendor hardware undergoes comprehensive testing by VMware hired 3rd-party company. (e.g. AppLabs acquired by CSC ... &lt;A href="http://www.csc.com/independent_testing_services/offerings/103857/103885-certify_your_product_with_csc_s_testing_services" title="http://www.csc.com/independent_testing_services/offerings/103857/103885-certify_your_product_with_csc_s_testing_services"&gt;Certify Your Product with CSC's Testing Services&lt;/A&gt; )&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;So if an old or some new hardware isn't listed it doesn't mean it couldn't work with VMware products. It could be just an indication that its vendor doesn't apply to have its HW on VMware HCL.&lt;/P&gt;&lt;P&gt;(such piece of hardware doesn't &lt;SPAN class="r"&gt;gone through&lt;/SPAN&gt; any extensive testing against VMware products or features)&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;... hence it&amp;nbsp; cannot be classified as certified (VMware Ready) and you cannot derive any support in relation to it from VMware GSS because its simply unsupported.&lt;/P&gt;&lt;P&gt;Apart from support ... because of a lack of complex testing you can encounter unpredictable behavior or crashes etc. ...&amp;nbsp; none of us want to see such hardware in production environment.&lt;/P&gt;&lt;P&gt;For Lab/Test environment its absolutely acceptable ... but not for production.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;So yes as you mentioned in these cases its all about luck ... (especially in production also about &lt;SPAN class="r"&gt;braveness and responsibility of each admin &lt;img class="lia-deferred-image lia-image-emoji" src="https://communities.vmware.com/html/@90D223CDF4C4491D7DFF693BB5C76865/emoticons/1f609.png" alt=":winking_face:" title=":winking_face:" /&gt;&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;In terms of updates I would always go for the latest maintenance releases.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Anyway your experience could be very valuable for others so if you will have success with IBM servers and VMDP I/O please ping back with results.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thanks&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hello,&lt;/P&gt;&lt;P&gt;Well I have success!&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;The Host has been upgraded to ESXi 5.1.0 U2 1483097 and the PCI Passthrough is working successfully.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;The PCI passthrough device is a dedicated PCI USB 3.0 controller, NOT an onboard device. I have not had time to test whether passing through a onboard device works as well due to a short Maintenance Window.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;When I get the opportunity I will test for others benefits.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thanks to vNEX for the very thought out responses. &lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;I was actually able to squeeze a little bit more time out of the Maintenance Window. My results below.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I attempted to pass through an onboard PCI USB2.0 controller and it would not work. When the VM got started a message came up saying "Device xxx is not a passthrough device".&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;So to summarise&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;IBM x3100 M4 Machine Type: 2582E4M&lt;/P&gt;&lt;P&gt;VMware ESXi 5.1.0, U2 (1483097)&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Onboard PCI USB 2.0 controller - FAILED - Message "Device xxx is not a passthrough device".&lt;/P&gt;&lt;P&gt;Dedicated PCI USB 3.0 controller - SUCCESS&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;In my opinion the main point to take away from this is there is greater chance of success passing through a Dedicated PCI USB device than an onboard one.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Once again thanks to vNEX for his contribution &lt;img id="smileyhappy" class="emoticon emoticon-smileyhappy" src="https://communities.vmware.com/i/smilies/16x16_smiley-happy.png" alt="Smiley Happy" title="Smiley Happy" /&gt;&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
