Product Description
The HP 817750-B21 is a high-performance dual-port network adapter designed to meet the increasing bandwidth demands of modern data centers and enterprise networks. Each port supports speeds of up to 25Gb/s, utilizing SFP28 transceivers, and connects to the host system via a high-throughput PCI Express 3.0 x8 interface. This adapter is engineered for applications that require significant bandwidth and low latency, such as high-performance storage, cloud computing, and data-intensive workloads. The dual-port design allows for network redundancy, load balancing, and increased aggregate throughput, enhancing the overall network resilience and performance. Key features often include support for Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE), which offloads network processing from the CPU and reduces latency. It also typically supports advanced virtualization features like Single Root I/O Virtualization (SR-IOV) for efficient network resource allocation to virtual machines. This makes the 817750-B21 a powerful solution for demanding server environments.
