Overview |
The main features of the Sun Dual Port 4x QDR IB Host Channel Adapter PCIe ExpressModule are as follows:
FIGURE 1-2 ExpressModule Without Metal Case
The ExpressModule includes the following interfaces:
The Sun Dual Port 4x QDR IB Host Channel Adapter PCIe ExpressModule is compliant with the InfiniBand Architecture Specification, Release 1.2. The ExpressModule has two compliant 4x InfiniBand ports (Port 1 and Port 2), each having four Tx/Rx pairs of SerDes. The ExpressModule provides access to these ports by means of two 4x InfiniBand connectors for external InfiniBand copper cables also compliant with the IBTA specification 1.2. Connector 1 connects to Port 1 of the device, while connector 2 connects to Port 2.
Furthermore, the ExpressModule is embedded with a media detect circuit that supports external InfiniBand active copper and fiber solutions.
The ExpressModule is compatible with the PCI ExpressModule Electromechanical Specification, Revision 1.1. The device can be either a master initiating the PCI Express bus operations, or a slave responding to PCI bus operations.
The ExpressModule has four LEDs located on the InfiniBand ports panel, with two LEDs for each 4x port. See FIGURE 1-3.
FIGURE 1-3 InfiniBand Ports and LEDs
The pair of LEDs for each port have the meanings described in TABLE 1-1.
The ExpressModule receives power from the server or workstation slot connector. All other required power is generated by ExpressModule switch-mode regulators. For power consumption see Appendix A.
A label on the Express Module enclosure displays the 64-bit GUID. This GUID uniquely identifies this device in the server and on the IB fabric.
