Overview of the HP Fabric Clustering System
This document contains the following sections that give installation information for HP Fabric:
• “About HP Fabric Clustering System for InfiniBand‘”
• “HP Fabric Clustering System Hardware Components”
• “HP Fabric Installation Prerequisites”
• “Install Fabric Adapters”
• “Install HP Fabric Software”
• “Install Fabric Switches”
• “Attach Cable Guides & Cables”
• “Internet Protocol over InfiniBand‘ (IPoIB)”
About HP Fabric Clustering System for InfiniBand
InfiniBand is an industry-standard high-speed, packet-based interconnect for node-to-node communications.
HP Fabric Clustering System for InfiniBand provides higher speed, lower network latency and uses less CPU
than other industry standard protocols (for example, Fibre Channel and Gigabit Ethernet). Instead of using a
traditional bus-based technology, HP Fabric is built around switched fabric architecture, providing the
bandwidth necessary for high speed data transfer. For more information on the InfiniBand standard see
“http://www.infinibandta.org”.
HP’s release of this clustering solution delivers the performance and scalability required by the following:
• Technical Computing Clusters supporting HP Message Passing Interface (MPI) based applications
HP Fabric Clustering System Hardware Components
This section describes the various HP Fabric products. For more information on HP Integrity server systems
that support HP Fabric products, see the HP Fabric Clustering System Release Notes, available at
http://www.docs.hp.com/en/netcom.html#Fabric%20Clustering%20System%20for%20InfiniBand.
NOTE This document uses the term HP Fabric Clustering System to refer to the hardware and
software that form the HP Fabric Clustering System interconnect product.

Other Product Elements
Other elements of the HP Fabric product family:
• HP 4X Fabric Copper Cables
— AB346A (5m length)
— AB353A (7m length)
— AB347A (10m length)
• The HP Fabric software consists of HP-UX drivers and user-space components as well as firmware on
fabric adapters and switches.
• Fabric software supports Remote Direct Memory Access (RDMA). RDMA provides higher bandwidth,
lower CPU overhead, and lower latency (the time a message takes to get from one point to another).

Installing HP Fabric Clustering System
The installation procedure for the HP Fabric clustering system installs the Switch, Host Channel Adapter
(HCA), cables, cable guide, and gets the system up and running.
Managing the Switch
The fabric switch can be used without being managed. This Installation Section does not include information
for managing HP Fabric. You can manage it using its Command Line Interface (CLI) - a text-based interface
accessible through a direct serial connection, Telnet over IP, or SSH over IP.
HP Fabric Installation Prerequisites
Before installing the HP Fabric product, ensure that the following hardware and software prerequisites are
met:
•Check the HP Fabric Clustering System Release Notes for known problems, required patches, or other
information needed for installation, available at http://www.docs.hp.com in the Networking &
Communications section.
