ESXi5 on HP BL685c-G7 Blades- What is the Max # Flex-NICs allowed?

Hi there. This is question for anyone out there with experience installing ESX(i) 4 or 5 on HP Blade Systems.

 

I have experience with BL460's but I have a questions regarding the Full height Blades. We are currently deploying HP BL685c G7 Blades - 8 per c7000 chassis. And plan to run ESXi-5-U1 on the blades. We realize that the BL685's come with 2 dual port CNAs -  which yields 4 LOMs per blade. If we carve out all of the possible bandwiths 4 per LOM then we are left with 16 Flex NICs. 2 Flex Nics will be used for FC.

That leaves 14 Ethernet Flex NICs that can be presented to the ESXi5 OS.

 

If we present all 14 Flex NICs to ESXi5 as VMNICs are we in violation of the VMware-ESXi5 Configuration Maximum of 8 10Gbe NICs allowed to be presented to ESXi5?

Would we be in an VMware Un-supported configuration?

 

Is it best to just carve out the required bandwith and only present 8 ethernet Flex NICs Max to the ESXi5 OS?

 

Thank you inadvance for your help. - Jorge

It would be best if you only carved out the NIC's that you need.

 

At a minimum, you need 2, but you'd probably want at least 4 or 6 depending upon the design.

 

Does your design call for 14 vmnic's? Do you have a design to share?
