Building on the example in Figure 10.5, and assuming a non-high-
availability configuration, Figure 10.6 shows a simplified I/O and network-
ing configuration using PCIe IOV along with converged networks. In Fig-
ure 10.6, instead of 16 PCIe adapters for a non-high-availability
configuration as in Figure 10.5, three adapters are shown.
In Figure 10.5, instead of dedicated PCIe adapters in each server, using
PCIe IOV, a PCIe extension connection extends from each server to a PCIe
adapter enclosure using multiroot IOV mode adapters that can be shared
across physical servers, reducing the number of I/O and networking compo- ...
