Advanced Features

In the dynamic data center environment, managers need flexible solutions that can evolve along with the technology to protect current investments in virtualization and server consolidation. The QLogic NetSlice architecture addresses these requirements by incorporating a unique degree of programmable support for virtualization. The NetSlice architecture creates a platform that exports a number of independent virtual interfaces, with each virtual interface utilizing a share of the existing (hardware) resources. Each virtual interface is serviced in a fair manner. Optionally, each interface can be assigned a priority that determines how much of a share of the underlying resources are allocated to that interface. Strong isolation is built around each interface to ensure that one interface does not adversely affect another. Dynamic power management modulates core frequency and core voltage to keep the controller operating at its ideal thermal and performance profile, increasing the reliability and uptime of the network. This feature provides a built-in warning and shutdown mechanism to protect the adapter in case of an extreme thermal condition. The QLE3142 also uses Single Root I/O Virtualization (SR-IOV), which provides broad interoperability and ease of device configuration/management in a virtualized environment.
