MPIO was deployed to \u201cteam\u201d the FC HBA\u2019s.<\/p>\n<p>One Ethernet NIC was presented from each Virtual Connect to each blade (2 per blade), with each NIC getting 6 Gbps.&#160; WS2012 NIC teaming was used to team these NICs, and then we deployed <a href=\"https:\/\/aidanfinn.com\/?p=12609\" target=\"_blank\">a converged networks design in WS2012 using virtual NICs and QoS<\/a> to dynamically carve up the bandwidth of the virtual switch (attached to the NIC team).<\/p>\n<p>Some testing was done and we were running Live Migration at a full 6 Gbps, moving a 35 GB RAM VM via TCP\/IP Live Migration in 1 minute and 8 seconds.<\/p>\n<p>For WS2012 R2, I\u2019d rather have 2 * 10 GbE for the 2 cluster &amp; backup networks and 2 * 1 or 10 GbE for the management and VM network.&#160; <em>If<\/em> the VC allowed it (didn\u2019t have the time), I might have tried the below.&#160; This would reduce the demands on the NIC team (actual VM traffic is usually light, but assessment is required to determine that) and allow an additional 2 non-teamed NICs:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" style=\"float: none;

However, the big plus of SMB 3.0 Multichannel would be that I would now have a potential 8 Gbps to use for Live Migration via SMB 3.0 <img decoding=\"async\" class=\"wlEmoticon wlEmoticon-openmouthedsmile\" style=\"border-top-style: none;
