vSphere Host NIC Design - 10 NICs
EDIT: 11/29/2011
I have no updated these to reflect vSphere 5 changes!
VMware vSphere 5 Host Network Design Layout and Configuration
EDIT: Updated 2/05/2010 - with new pictures of vSphere vSwitch and vDS
**One thing that i completely forgot to mention is that in my diagrams, I have 2 stacked Cisco 3750G switches. I forgot to put the stacking cable in the diagram. But just know that every configuration should be using some sort of stacked switching**
There was some talk going on the past 2 days about Host NIC configurations. @Kiwi_Si is hosting a poll on his site, TechHead.co.uk,to see the most common configuration among our peers. Which inspired me to create this post.
This is what I like to do on my configurations. Use the 2 on-board NICS with 2x4Gb Expansion NICs, giving me a grand total of 10 NICs to play around with. Here is a diagram of how I plan to design my vSphere NIC layout. I still haven't fully configured Fault Tolerance on a set of physical servers, so let me know if you see something is amiss.
Thanks to a pointer from @darylhunter, be careful mixing the On-Board Broadcom NICs w/ the Intel 4x1Gb PCI NICs. There can be issues such as flow control.
