Blade Physical-Virtual Networking and Virtualization Security

I have been thinking about blades and virtualization security for some time spurred on by a conversation with Brad Hedlund six months ago. Nearly all my customers use Blades and virtualization security is a big concern to them. In my Rethinking vNetwork Security article, I touched on some of the issues in response to Brad’s comments a while back. I would like to now expand that discussion to blades.

There are three sets of blade enclosures I would like to discuss, those that use pass thru networking, those that use standard switching fabric within the enclosures, and those that use flexible interconnects such as HP Flex-10 and Cisco Palo adapters. The last is the so called physical-virtual network device.
