The document discusses network-based I/O virtualization (IOV) and its role in modern server design trends. IOV allows servers to access resources through a fabric and is a building block of fabric computing. Customers value IOV capabilities from their existing server vendors and see IOV complementing traditional I/O cards. Ethernet and PCI-Express have provided common connectivity standards that IOV can build upon.

2. Server design trends Scale out architectures are driving efficiency, density, and novel form factors Physical networks converging on Ethernet, with diverse protocols for applications Fabric computing model, where servers can access resources via the fabric Server Design Summit 2010 Santa Clara, CA
