Let MindShare Bring IO Virtualization to Life for You

Virtualization is one of the hot, exciting areas in the PC industry today, generating significant revenue, and solving critical problems in the PC data centre. However, software virtualization techniques add too much overhead to allow virtualization to be used for some applications. This class will look at those problem applications and the hardware solutions defined by the PCI SIG. The course focuses on the Intel processor SoC or Chipset VT-d and VT-d2 elements that support DMA and Interrupt remapping. The course also discusses details of single root IOV (SRIOV) implementation (though not multi-root IOV MRIOV).
