This includes, but is not limited to vSphere vMotion, vSphere FT, vSphere HA and VSAN.<\/p>\n<p>&nbsp;<\/p>\n<p>When talking about different VMkernel TCP\/IP stacks, VMware differentiates between 3 major TCP\/IP stacks:<\/p>\n<ul>\n<li>Default TCP\/IP stack<\/li>\n<li>vMotion TCP\/IP stack<\/li>\n<li>Provisioning TCP\/IP stack<\/li>\n<\/ul>\n<p>Let&#8217;s take a look at the details of each TCP\/IP stack:<\/p>\n<h2>Default TCP\/IP stack<\/h2>\n<p>Management traffic between ESXi hosts and vCenter server are considered as the default TCP\/IP stack. Also, host related traffic like vMotion, NFS\/iSCSI storage, HA and vSphere FT are part of it.<\/p>\n<h2>vMotion TCP\/IP stack<\/h2>\n<p>By creating a VMkernel port on the vMotion TCP\/IP stack you can isolate vMotion traffic to this stack. By doing so, vMotion traffic will be disabled on the default TCP\/IP stack. The vMotion TCP\/IP stack is used for live VM migrations.<\/p>\n<p>VMware recommends configuring a separate vMotion TCP\/IP stack and isolate management traffic from vMotion traffic.<\/p>\n<h2>Provisioning TCP\/IP stack<\/h2>\n<p>The provisioning TCP\/IP stack is used for cold VM migration, cloning and snapshotting traffic. In case of a long-distance vMotion\u00a0(new in vSphere 6), NFC traffic can be configured to use the provisioning TCP\/IP stack. Setting up a provisioning TCP\/IP stack is useful when you want to isolate this traffic from other TCP\/IP stacks.\u00a0A dedicated provisioning TCP\/IP stack is common in VDI environments and in setups with frequent VM snapshots.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What are the VMkernel TCP\/IP Stacks?
