Upgrading NIC in FMCv

[Ken Stieers]

So, my vFMC is pretty slow, and the more I'm digging as our project moves forward the more annoying that gets.  So I googled and found an article (https://www.lammle.com/post/make-cisco-virtual-fmc-drastically-faster-5317/) that makes some sense...

I've only got 2 boxes feeding it, so 4cpu and 12gig ought to be enough, but I bumped it up...

As far as swapping the nic out, what's the best way to keep the FMC happy?  The VMware side is simple, remove/add, use the same MAC address...

Will I need to reconfigure the nic?  Should I add a new one, move the IP, remove the old one?

Any advice would be appreciated.

Thanks!!

Virtual FMC performance has been problematic. I can't say I agree with Todd's tweaks as the (admittedly limited) experience I have does not show that maxing out the cores and memory helps appreciably.

Under the covers mysql is using only a single CPU core and that's not something you can change without potentially breaking a lot of things.

I haven't seen network IO be such that a more efficient or faster NIC would help. But if you're doing it as long as you retain the MAC address (it's used in the classic license key), you should be fine transparently changing out the NIC in VMware.

Cisco has been gradually moving the FMC databases to SAP SQL Anywhere and that may help in the longer term.
