Running VMware on legacy infrastructure is like driving a Ferrari on a gravel road. If you look at what is run in most production VMware environments today, the only really new things in the environment is VMware vSphere, and possibly some new monitoring, security and backup tools. We have barely started to reinvent everything that needs to be reinvented in order to properly take virtualization, IT as a Service and public clouds to their logical and most beneficial conclusions.
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.
