Product Review

The Mellanox 45W6653 is a 100Gb/s QSFP28 passive copper cable that supports lengths up to 5 meters. It is designed for high-speed interconnects and provides a cost-effective solution for high-bandwidth data center applications. The cable is compliant with SFF-8436 and IEEE 802.3bj standards and can be used in both Ethernet and InfiniBand applications.


The Mellanox 45W6653 is a high-performance network interface card (NIC) that provides two ports of 40 Gigabit Ethernet (GbE) connectivity in a single PCIe 3.0 x8 card. It is designed for high-speed networking and storage applications, including cloud computing, high-performance computing (HPC), and big data analytics. The 45W6653 supports a range of advanced networking technologies, including remote direct memory access (RDMA) over Converged Ethernet (RoCE), Ethernet, TCP/IP, and iSCSI. This makes it ideal for a wide range of data center applications that require high bandwidth and low latency. One of the key features of the 45W6653 is its support for RDMA over RoCE technology. RDMA over RoCE allows data to be transferred directly from the memory of one server to the memory of another server, without involving the CPU or operating system of either server. This results in lower latency, higher throughput, and reduced CPU overhead, making it ideal for high-performance applications such as HPC and big data analytics. The 45W6653 also includes a range of advanced features and technologies to ensure high performance, reliability, and scalability. These include advanced congestion control, network virtualization, and quality of service (QoS) features. Overall, the Mellanox 45W6653 is a high-performance and versatile network interface card that provides advanced networking and storage capabilities for data center applications. Its support for RDMA over RoCE technology, advanced features, and high reliability and scalability make it an essential component for building high-performance and efficient data center networks. The dual-port 40 GbE design of the 45W6653 also provides increased bandwidth and flexibility for data center deployments.
