    10Gbps connections per port in each direction. Each HCA and associated protocol drivers are designed to run in conjunction with an HP Dual-port 4x Fabric Adapter. The HP Dual-port 4x Fabric Adapters feature a full suite of upper-layer protocols and APIs.

  • Page 14: Hca Package Contents

    • Limited Warranty and Material Limitations Documentation About the HCA Drivers The HP Dual-port 4x Fabric Adapters provide a full suite of upper-layer protocols, including IPoIB, SDP, SRP, MPI and uDAPL. IPoIB IPoIB is a required protocol; it allows the IP network to utilize the InfiniBand fabric. It is used by SDP and uDAPL to resolve IP addresses.

  • Page 18: Selecting The Host Connector

    • “Installing HCA Host Drivers” on page 15 Selecting the Host Connector The following types of connectors are supported: • “Selecting PCI-X Connector(s)” on page 6 • “Selecting PCI-Express Connector(s)” on page 7 Selecting PCI-X Connector(s) The HCA requires that specific PCI-X slots be used. When determining which PCI-X slot to use, inspect the server chassis and keep the following in mind: Consider the Speed of the Slot Locate the 133MHz PCI-X (64-bit, 3.3V) or 100MHz PCI-X (64-bit, 3.3V) slots.

  • Page 19: Selecting Pci-express Connector(s)

    Consider Dual HCA Installation Requirements • For dual HCA installation in a single host, it is required to have two completely isolated PCI-X buses to avoid any performance degradation. • If the host has only one PCI-X 100 or 133MHz bus (regardless of the number of connectors), then this mother board should not be used for a dual HCA installation.

  • Page 20: Selecting The Type Of Installation

    • Installation of this HCA should be performed by individuals who are both qualified in the servicing of computer equipment, and trained in the hazards associated with products capable of producing hazardous energy levels. • To reduce the risk of personal injury from hot surfaces, allow the internal system components to cool before touching.

Installing HCA(s) in a 2U+ Host with PCI-Express Connectors The HCA comes preconfigured. You do not have to set any jumpers or connectors. To install the HCA: Note the Global Unique ID (GUID) numbers from the hardware.

    Plug InfiniBand cables from the host to the InfiniBand switch. To plug in an InfiniBand cable, push the connector into the interface until you hear/feel a click. Figure 2-2: Fully Installed IB Cable with Pinch Connector...

  • Page 26

    NOTE: If your host does not provide an ample amount of free space around a given IB port, double-check that your IB cable connector engages fully. Wiggle your connector back and forth to be sure that both sides of the connector have locked firmly into place. To remove a cable with a pinch connector, pinch both sides of the back of the connector and pull the connector away from the port.

    Sample Test Plan The following evaluation test plan will walk you through basic setup of the InfiniBand-based switching fabric, introduce you to some of the ULPs (Upper Layer Protocols) supported on the fabric, and perform some basic tests that showcase the fabric's performance. Overview •...

    low latency aspects of the fabric, a minimum of dual Xeon servers (in the neighborhood of 2.0 GHz) with 133Mhz PCI-X expansion busses are required. • An Ethernet switch should be used to network the two servers together. This switch can be of any speed, but a gigabit version will provide the best platform for comparing high performance communication over Ethernet and InfiniBand.

  • Page 81: Ipoib Setup

    IPoIB Setup About IPoIB IPoIB (IP over InfiniBand) is simply that: IP packets running over the InfiniBand fabric. This protocol is useful for testing connectivity into the fabric between two hosts, and also for taking advantage of the high speed fabric for “legacy” applications that are written to communicate over IP. The drawback to using IPoIB compared to standard Gigabit Ethernet is that the operating system must do packet checksumming, whereas modern NIC cards usually offload this function to hardware.

  • Page 82: Ipoib Performance Vs Ethernet Using Netperf

    IPoIB Performance vs Ethernet Using netperf To test the performance characteristics of IPoIB, use a tool called netperf. This utility runs on both machines with one machine listening on a TCP socket and the other connecting and sending test data. The listening program is called netserver while the test client is called netperf.

  • Page 83: Perform A Latency Test

    Perform a Latency Test To demonstrate the latency advantage of InfiniBand compared to Ethernet, use a netperf test called TCP request/response. This test will send a 1 byte request to the remote machine and the remote machine will issue a 1 byte response. Develop a base case for comparison on Server 1.

    10. Make sure processes include the SDP library when they load. The /etc/ file tells the system's dynamic linker to load the SDP library when processes are started. Create the /etc/ file if the file does not exist. Add the following line to /etc/ on both systems: /lib/ 11.
