Product Review

The Mellanox 45W6654 is a dual port Infiniband Host Bus Adapter designed for high-performance computing, cloud computing, and storage applications. It has a PCIe 3.0 x8 interface, supports data transfer rates of up to 56 Gb/s, and features Mellanox's Virtual Protocol Interconnect technology for enhanced performance and scalability. Additionally, it supports RDMA over Converged Ethernet (RoCE) technology for low-latency, high-bandwidth data transfers.


Mellanox 45W6654 is a dual-port, 10 Gigabit Ethernet (GbE) network interface card (NIC) designed for high-performance computing (HPC), cloud computing, and storage applications. It features two SFP+ ports, providing a total bandwidth of up to 20 Gbps. The 45W6654 supports a range of network protocols and technologies, including Ethernet, TCP/IP, iSCSI, RDMA, and RoCE (RDMA over Converged Ethernet). This makes it suitable for a wide range of data center applications, including storage networking, virtualization, and cluster computing. One of the key features of the 45W6654 is its support for Remote Direct Memory Access (RDMA) technology. RDMA 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 45W6654 also includes a range of advanced features and technologies to ensure high performance, reliability, and scalability. These include support for advanced congestion control, network virtualization, and quality of service (QoS) features. Overall, the Mellanox 45W6654 is a high-performance and versatile network interface card that provides advanced networking and storage capabilities for HPC, cloud computing, and storage applications. Its support for RDMA technology, advanced features, and high reliability and scalability make it an essential component for building high-performance and efficient data center networks.
