Most vendors in the I/O virtualization space take the PCI Express extender (PCIe) approach. With this implementation, the server's PCIe bus is extended by a cable to a gateway box that houses standard I/O adapters, which are shared among the servers attached to the cage. Users may find this approach beneficial in terms of cost and performance. In this podcast, George Crump, lead analyst for Storage Switzerland, discusses using PCIe bus extenders to implement I/O virtualization.

In this podcast, find out:

• What PCIe bus extenders are and how they're implemented.
• PCIe bus extenders' advantages and disadvantages for users.
• Vendors in the space of PCIe-based I/O virtualization.
• And more.
