So if you have two 8Gbps FC links, you can combine them to a nice big 16Gbps FC pipe.  Its similar to ethernet port-channels but you do it with the SAN.<\/p>\n<p>Now, you may have different <a href=\"http:\/\/en.wikipedia.org\/wiki\/VSAN\">VSANS<\/a> that you want to go over this pipe.  Well, if you are in non-trunking mode, you can not do it.  You are only allowed one VSAN.  In UCS, this is the default setting.  No trunking.  This usually works fine and in my environment I have no reason to change it. <\/p>\n<p>However, if I had multiple VSANS then I&#8217;d want to make a trunk out of it.  This requires a bit extra wizardry on UCS.  But it is documented <a href=\"https:\/\/supportforums.cisco.com\/servlet\/JiveServlet\/downloadBody\/14838-102-1-34449\/UCS_1-4-1_F-port_channel-trunk-v1.pdf\">here<\/a>.  <\/p>\n","protected":false},"excerpt":{"rendered":"<p>One of the fun things I get to do is learn about Fiber Channel technologies.
