IO Virtualization Approaches: VMworld 2010 Review

There seem to be three styles of IO Virtualization (IOV) taking place within the virtual environment. At VMworld, the IO Virtualization companies were out and talking to people about their wares, products, and approaches to IO Virtualization. These three methods are:

* Converged Network Adapters used within Cisco UCS, HP Matrix, etc.
* Attached IOV top of rack devices such as the Xsigo Device
* PCIe Extenders

Each of these provide unique benefits to your virtual environment but which to use? First, we need to know what each of these approaches brings to the table.


VLANs/FCoE/CNA – Mixed Security Data on One Wire

Over the past year or so I have been thinking pretty heavily about the direction networking is taking within virtualization. In some ways, it appears security has been forgotten or relegated to ‘encrypt’ and forget. However, it takes quite a bit of knowledge and time to properly set up the backbone of an ‘encrypt’ and forget approach to network security, so it does not happen. Instead, we have a proliferation of technologies being used to cut down on cable clutter and thereby consolidate the network. These are all very important concepts. Security practitioners like myself realize that this type of consolidation WILL happen. So what tools are required to either ‘encrypt and forget’ or to protect these consolidated networks?
