Product Review

The Mellanox 45W6655 is a 10Gb Ethernet NIC adapter that supports both SFP and SFP+ transceivers. It is designed to provide low-latency and high-bandwidth connectivity for applications such as cloud computing, virtualization, and storage. The adapter uses PCIe 2.0 x8 interface and supports features such as jumbo frames, VLAN tagging, and TCP/IP offloading. It is compatible with Windows, Linux, and VMware operating systems.


Mellanox 45W6655 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 QSFP+ ports, providing a total bandwidth of up to 40 Gbps. The 45W6655 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 45W6655 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 45W6655 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 45W6655 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. The dual-port QSFP+ design of the 45W6655 also provides increased bandwidth and flexibility for data center deployments.
