BNA driver fully supported

The Brocade BNA driver for Brocade 10Gb PCIe ethernet Controllers is no longer a Technology Preview. In Red Hat Enterprise Linux 6.3 the BNA driver is fully supported.

SR-IOV on the be2net driver

The SR-IOV functionality of the Emulex be2net driver is considered a Technology Preview in Red Hat Enterprise Linux 6.3. You must meet the following requirements to use the latest version of SR-IOV support:

  • You must run the latest Emulex firmware (revision 4.1.417.0 or later).
  • The server system BIOS must support the SR-IOV functionality and have virtualization support for Direct I/O VT-d.
  • You must use the GA version of Red Hat Enterprise Linux 6.3.
SR-IOV runs on all Emulex-branded and OEM variants of BE3-based hardware, which all require the be2net driver software.
