What is VM-FEX? VM-FEX is the consolidation of the virtual switch and physical switch into a single management point.
This sounds funny to say, but it amazes me how many people still use standard VMware vSwitches. In the enterprise there are just too many things that can be missed on standard vSwtiches and we need consistency. This consistency is obvious when port group names need to match identically or vMotion will fail. Last time I went through the VMware vSphere: Install, Configure, Manage class we were working on the standard vSwitch configuration, which utilizes some interesting port group failover order setting which include overrides. So, I zipped through my sheet and was waiting for the instructor to ask for answers. After a few other students I spoke up and proceed to explain my complex but accurate vSwitch configuration.
I make no bones about it I love the Cisco Unified Computing System (UCS). Yes, you’re reading a Cisco Blog…so you’d expect nothing less, but understand I came to love the system long before I was ever a Cisco employee. In fact it’s the reason I’m here – well that and the paycheck. You can read a bit about my “conversion” here: Something to Believe In. Or if you’d prefer to watch me talk about the UCS as a GE employee take a peek here
