Product Features

Sun Dual Port 4x IB Host Channel Adapter PCI-X card features include:

Dual 10 Gb/sec (4x) InfiniBand ports

Integrated serializer/deserializer (SerDes)

PCI-X Revision 2.2-compatible

64-bit or 32-bit 133 MHz PCI-X

InfiniBand Trade Association (IBTA) version 1.1 interoperability

Dual copper connectors (MicroGigaCN)

Hardware Description

The Sun Dual Port 4x IB Host Channel Adapter PCI-X card is an InfiniBand (IB) host channel adapter (HCA) card and is referred to as the IB-HCA in this manual. This adapter is a PCI-X Revision 2.2, 64-bit, 133MHz compatible card with dual 4x MicroGigaCN InfiniBand-compliant connectors for copper cables. FIGURE 1-1 shows the IB-HCA card.

The board characteristics are:

Power: approx. 12 watts total

Low profile PCI form-factor card (approx. 2.5 in. by approx. 6.7 in.)

Requires 4x InfiniBand cables

3.3V PCI-X or PCI slot (Note that the IB-HCA can not be plugged into a 5V connector.)

Link status indication LED

Two 4x InfiniBand (IB) ports

Two faceplate sizes: standard and low profile

The standard PCI/PCI-X interface is used for data traffic, management traffic, and to generate and receive inbound configuration packets.FIGURE 1-1 Sun Dual Port 4x IB Host Channel Adapter PCI-X Card

I/O Interfaces

The IB-HCA includes the following interfaces:

Two 4x InfiniBand copper connectors

PCI-X 64-bit 133 MHz edge connector

InfiniBand Interface

The IB-HCA provides two 4x InfiniBand v1.1 connector (or ports) for external copper cables and is IBTA specification 1.1-compliant.

PCI-X Interface

The PCI-X bus is a PCI-X version 2.2-compliant 64-bit 133 MHz interface. The adapter can be either a master initiating the PCI bus operations or a slave responding to PCI bus operations. The PCI/PCI-X bus can connect to a host CPU in an HCA application.

LED Displays

Two InfiniBand ports connectors are located on the front panel of the adapter. Each port has two LEDs, as shown in FIGURE 1-2. An explanation of the LEDs is given in TABLE 1-1.

TABLE 1-1 IB-HCA LEDs
Color	Meaning
Green	Physical Link - The physical link LED illuminates once the Tavor driver is successfully attached to the port.
Amber	Logical Link - The logical link LED illuminates once the InfiniBand port is in the Up state. This LED also blinks when there is traffic on the port.
