Server-Specific Information
Selectable Network Drivers |

|
The following sections describe network drivers and devices that are selected during installation rather than automatically installed. Asynchronous Transfer Mode (ATM), ATM-00, product supports Classical IP and Lan Emulation over ATM protocols. ATM-00 software is compliant with UNI 3.0, 3.1 and 4.0 versions of ATM Signaling. All the supported ATM adapters work with MC/ServiceGuard to provide local and remote recovery high availability features. ATM adapters also support Online Addition and Replacement (OLAR) of PCI cards. The ATM networking solution is now available on enterprise Itanium-based platforms. Only the ATM adapter A5513A (155Mbps MMF) is supported on Itanium-based platforms. For further information on HP-UX ATM networking connectivity, refer to http://docs.hp.com/hpux/netcom/index.html#ATM. HyperFabric is a high-speed, packet-based interconnect for achieving node-to-node communication. HyperFabric provides higher speed, lower network latency and less CPU usage than other industry standard protocols (e.g. Fibre Channel and Gigabit Ethernet). Instead of using a traditional bus-based technology, HyperFabric is built around switched fabric architecture, providing the bandwidth necessary for high speed data transfer. The HyperFabric hardware consists of host-based interface adapter cards, interconnect cables, and optional switches. The HyperFabric software resides in Application Specific Integrated Circuits (ASIC) and firmware on the adapter cards and includes user space components and HP-UX drivers. The clic_ping(1M) manpage is not delivered in HP-UX 11i v2. The following documents can be found at http://docs.hp.com/hpux/netcom/index.html#HyperFabric:
INTL100 is a LAN driver for Intel 82559 ASIC-based LAN ports. This driver controls the management LAN ports of the HP Integrity rx5670 and rx2600 servers and the management port of the HP zx6000 workstation. INTL100 is required for the HP Integrity rx5670 and rx2600 servers and the HP zx6000 workstation. The Online Addition and Replacement (OLAR) of PCI/PCI-X I/O adapter cards is a feature that provides the capability for adding and replacing of PCI/PCI-X I/O cards while a system is running thus eliminating the need to reboot. This feature is delivered as part of the core HP-UX functionality. The enhanced OLAR functionality delivered in HP-UX 11i v2 is new for Itanium-based systems. It enhances the overall high-availability solution provided since a system can remain active during the addition or replacement of an OLAR capable I/O adapter cards. The new olrad(1M) command provides the command line interface for OLAR functionality. It provides the ability to execute a critical resource analysis routines to ensure that the system integrity is not compromised before performing an OLAR operation as well as the actual OLAR operations. Some systems support the use of Doorbells or Attention-Buttons on its slots that can be used to manually trigger an OLAR operation. This capability is provided by the new hotplugd(1M) daemon. The HP-UX Peripheral Device Tool provides a graphical user interface for performing OLAR operations. For more information, see “HP-UX Peripheral Devices (pdweb)”. The OLAR functionality is now provided on Itanium-based systems with this release of HP-UX. When combined with other high availability products, such as MC/ServiceGuard, the system availability can be improved significantly. The new olrad(1M) and hotplugd(1M) manpages are delivered in HP-UX 11i v2. Additionally, these documents, available at http://docs.hp.com, are introduced in this release:
The PCI Multiplexer (Mux) is a high-speed, serial communications, multiple port product available in two adapters A6748A (8-port Mux) and A6749A (64-port Mux). Along with several different modular components, these adapters provide multiple serial ports which can be configured in a variety of combinations, to satisfy most applications. The PCI Mux networking solution, TermIO-00 version B.11.23.01, is now available on Itanium-based platforms with the release of HP-UX 11i v2. Documentation regarding PCI Mux networking is found at: http://www.docs.hp.com/hpux/netcom/index.html#EISA/PCI%20Multiplexer The PCI Token Ring adapter card, A5783A, is a 32-bit, bus master, high-speed token ring networking solution that supports the IEEE 802.5 Token Ring standard and is delivered with HP-UX 11i v2. The adapter provides networking on PCI-based servers and workstations via the PCI bus specifications in HP-UX and the use of the pcitr driver, J1644AA. The PCI Token Ring adapter runs at 4, 16, or 100 Mb/s over shielded twisted pair (STP) cabling via a 9-pin, D-shell connector and unshielded twisted pair (UTP) via an RJ-45 connector without the need for a user make a selection. No more than one data cable may be connected to the PCI Token Ring adapter at a time. This adapter also operates in full-duplex mode when connected to a full-duplex capable switch or Dedicated Token Ring (DTR). The PCI Token Ring NIC operates at a bus speed of 33 MHz. The PCI Token Ring networking solution is now available on Itanium-based 64-bit platforms with the release of HP-UX 11i v2. The capability to connect to PCI Token Ring networks from an Itanium-based system is now available. More information on the product can be found at: Documentation regarding PCI Token Ring networking is found at: The high-speed PCI Token Ring adapter, A5783A, is the replacement for A4930A, which was discontinued by IBM. The A4930A product, which was discontinued as of June 1, 1999, is supported on V-class machines only. Should an existing A4930A card fail, it should be replaced with the replacement A5783A card. When the A4930A card is replaced with the new A5783A card, the pcitr driver must be upgraded to J1644AA. |
