What are the Compatible Cables and Transceivers for Mellanox ConnectX-4?

What are the Compatible Cables and Transceivers for Mellanox ConnectX-4?

Overview of Compatible DAC Cables and Transceivers

The selection of DAC and transceivers must complement the integration with the Mellanox ConnectX-4 adapter to provide a seamless experience. This adapter supports several Direct Attach Coppers with cables and optical transceivers that meet known networking standards. In most cases, the recommended transceivers and DAC cables are Mellanox ones or certified by Mellanox because such components have been extensively tested to pass the required performance and reliability criteria necessary for the ConnectX-4 adapter. Depending on the configuration and cable length, this can support data rates of up to 100Gb/s. A supported combination of components that may work in that particular environment can be procured after consulting Mellanox or Lenovo’s specific product documentation and compatibility lists.

Choosing the Right SFP28 for Your Network Needs

Every manufacturer of SFP28 modules guarantees that their equipment is wholly compatible with interfaces of other vendors and easily passes the interoperability tests. SFP28S embedded multi-chip modules applications supporting 25G port architectures, which include Level II interconnects in switch components through a copper wire, are expected to emerge during the middle of this decade. An SFP28 network connection can extend up to 300m over a Nexxia cable or 100m via directly attached copper cables. The complement SFP28 to 802.3bm-subcode is designed for work within data centers interconnected by wires. There are many manufacturers of SFP28 modules, which creates competition, and not a single module guarantees communication interoperability through established protocols.

Installation and Configuration of Transceivers

The first step is to power down the device to which the 25 GB Ethernet adapter will be mounted. After the Machine has been powered down, the 25gbe adapter has to be fixed into the designated slot by sliding it in until it is held firmly in place. This step is crucial as if the transceiver and the port are irreparably damaged due to misalignment during the process. Once the adapter is attached, replacing the power supply to the attachments ensures that the system recognizes the transceiver. Configuration is done by going into the configurations of the host to ensure that the interconnect is correctly configured to the desired bit rate and to the network protocols to be used. Usually, manufacturers develop specific software tools that check the performance of interconnected components and the network transceiver for configuration and monitoring. The entire Transceiver and Adapter installation & Configuration processes should be done with the manufacturers’ provided information documentation so the configurations are done correctly and all functionalities work optimally.
