of the Ethernet forwarding schemes and integrates with existing Fibre Channel networks and management software. Computers connect to FCoE through CNAs. Function A PCIe function. Each function can be configured by HP-UX as a single device: an FCoE device or a LAN device. HP-UX can configure a dual-ported CNA with as many as 8 PCIe functions (up to four per port) in a Flex-10 environment.
More recent revisions of the PCIe standard support hardware I/O virtualization. Port The physical connection to the network. A CNA may have two physical connections; this configuration is often described as “dual-ported.” CNA overview The CNA is a PCIe device that can be configured by HP-UX as a number of LAN and FCoE devices depending on the system configuration. Most CNAs are dual-ported.
are simple but require too many cumbersome cables and create complexity. Blade switches reduce the number of cables but add more management responsibilities for LAN and SAN administrators. In both cases, multiple people are needed to perform very simple server tasks. Only HP offers the third choice — HP Virtual Connect.
2 servers. With this feature, the server does not need to be powered off to perform any of these operations on a network adapter. The feature is supported with the following network adapters on Superdome 2 servers: • AT094A • AT111A • AT118A Support of this feature requires the following be installed on your Superdome 2 server: • The latest version of the NIC (iocxgbe) and Fibre Channel (fcoc) drivers (B.11.31.1209 or later) • HP-UX operating system B.11.31.
Changed features The iocxgbe driver has been enhanced with performance and stability improvements. Problems fixed in this and recent versions This section describes any problems fixed in this and recent releases of the 10GigEthr-03 product.
Problems fixed in recent releases SR number Description QXCR1001311463 LAN connectivity failure when using HPVM Guest based VLANs LAN connectivity failure when using HPVM Guest Based VLANs (GBV) over a vswitch backed by a LAN interface, if there is no VLAN configured on LAN interface on VSP. QXCR1001292744 Install script overwrites the entry in nettlgen.conf unconditionally When updating the product, the corresponding nettlgen.conf entry goes back to the default setting.

Multi-queue enables traffic to be partitioned across CPUs. The CNA supports only receive multi-queue operation. Multiple queues are supported only on the first PCIe function for each port: function 0 (port 0) and function 1 (port 1). The iocxgbe driver sets the number of receive queues for each of these PCIe functions to 5. For each remaining PCIe function, the number of queues is 1 and remains 1.
NOTE: NC552m is only supported on HP Integrity servers with the adapter firmware version indicated in the HP-UX Ethernet Card Support Matrix. If you purchase an NC552m as a standalone product, it might ship with a lower or higher adapter firmware version preinstalled. Before booting HP-UX, you must install the indicated firmware version. Firmware requirements for the newly-supported OL* feature are listed in “New features introduced with 10GigEthr-03 (iocxgbe) B.11.31.1209” (page 7).
