That can be troublesome, especially when people are buying servers with lots and lots of NICs.&#160; Document everything, and only use what you need.&#160; Here\u2019s just a few tips:<\/p>\n<p><strong><u>Tip #1<\/u><\/strong><\/p>\n<p>Label your network connections with something descriptive such as \u201cParent\u201d, \u201cCSV\u201d, \u201cVM1\u201d, \u201cLM\u201d, or \u201ciSCSI1\u201d, instead of the useless \u201cLocal Area Connection 2\u201d.&#160; This allows you to track what is doing what.<\/p>\n<p><strong><u>Tip #2<\/u><\/strong><\/p>\n<p>Disable unused NICs.&#160; They just clutter up stuff all over the place.&#160; And they can cause a nightmare in when they are patched into DHCP networks.<\/p>\n<p><strong><u>Tip #3<\/u><\/strong><\/p>\n<p>Do not disable IPv6, even if you have no IPv6 on your network.&#160; MS will support you, but it\u2019s recommended that IPv6 is left bound to all the physical NICs in your cluster nodes.&#160; I recently had that discussion with MCS on a customer site.&#160; A reach out to Redmond gave us this recommendation.<\/p>\n<p><strong><u>Tip #4<\/u><\/strong><\/p>\n<p>Disable everything except for the Hyper-V switching protocol on the host NICs that are used for VM networking once you verify that they are patched into the right network(s).&#160; This is to prevent the host being a n accidental participant on a guest\u2019s network if that VLAN has a DHCP scope.&#160; It also keeps things tidy.<\/p>\n<p><strong><u>Tip #5<\/u><\/strong><\/p>\n<p>Unbind everything except for TCP on the iSCSI network (which should be a dedicated network for iSCSI with dedicated switches).&#160; I found that you can get some weird funnies like CSV suddenly not cooperating if you don\u2019t.<\/p>\n<div style=\"padding-bottom: 0px; margin: 0px; padding-left: 0px; padding-right: 0px; display: inline;
