As part of the vSphere launch and GA activities, we created a set of short “Meet the Engineer” videos. In these videos, the key architects and engineers talk about the vSphere 4 features for which they were responsible. It’s great viewing and provides an insight into the features from the engineers’ point of view. You can see them on the VMwareTV channel on You Tube.
Two videos of note (on networking, of course):
There are plenty of other videos as well, and we will continue to post and update as time goes on. So subscribe to the channel!
Horst Mundt, one of our technical account managers in Germany, recently queried the VMware internal “network” alias for suggestions on a simple virtual appliance that acts as an Ethernet bridge. A flurry of replies ensued. Horst collated the replies into the list below that I thought was worth sharing.
Note: do this in your lab, not in your production network! A bridge will create a loop in your network if run across two uplinks (vmnics). You’ve been warned! Also note, you will need to alter the port security settings on the bridge to allow for forged transmits.
Here is Horst’s list:
1. If you’re also in need of monitoring capabilities, I’d recommend Network Security Toolkit VA http://www.vmware.com/appliances/directory/141
2. Linux bridge module. It can be used to act as a bridge between 2 vnics.
3. Wanem (WAN Emulator) although main purpose is to emulate a wide area network with delay/drop/reordering/etc.
4. You can even use Windows 2003 to bridge multiple NICs. You can highlight multiple interfaces and bridge them. You create the bridge in the "network" window (where you see "Local Area Connection 1", etc. Just shift click on the NICs in question and you can right click and select bridge. (BTW this also works with XP)
5. The community version of Vyatta.
ISO and VA are available.
6. Use a basic linux VM and setup the bridge as follows (to bridge eth1 and eth2):
brctl addbr br0
brctl addif br0 eth1
brctl addif br0 eth2
ifconfig br0 up

This posting comes by way of Rick Vanoever from Virtualization Review:
I am really excited
for the upcoming product from VMware. In my opinion, this is a good time to
make a final decision on ESX vs. ESXi. For current VI3 environments, ESXi has
most of the functionality of ESX and all of the licensed features are
available. This KnowledgeBase article has a good breakdown of the differences
as they exist today. For anything that you can’t do on ESXi directly, chances
are you can do it either via the Remote Command Line or VI Toolkit.
