Interfaces

InfiniBand Interface

The network ports of the ConnectX®-5 adapter cards are compliant with the InfiniBand Architecture Specification, Release 1.3. InfiniBand traffic is transmitted through the cards' QSFP28 connectors.

Ethernet QSFP28 Interface

The network ports of the ConnectX®-5 adapter card are compliant with the IEEE 802.3 Ethernet standards listed in Features and Benefits. Ethernet traffic is transmitted through the cards' QSFP28 connectors.

PCI Express Interface

TThe ConnectX®-5 adapter card supports PCI Express Gen 3.0 (1.1 and 2.0 compatible) two PCIe x8 edge connectors; x8 edge connector on the adapter card and x8 edge connector on the auxiliary PCIe connection card accessible through the Slim Line-SAS cable. The device can be either a master initiating the PCI Express bus operations, or a slave responding to PCI bus operations.

• PCIe Gen3.0 compliant, 2.0 and 1.1 compatible

• 2.5, 5.0, or 8.0, or 16.0 GT/s link rate x8

• Auto-negotiates to  x8, x4, x2, or x1

• Support for MSI/MSI-X mechanisms

LED Interface

There is one bi-color (yellow/green) I/O LED per port to indicate link status located on the adapter card.
