Lenovo 00D9690 netwerkkaart Intern Fiber 10000 Mbit/s

High-performance computing (HPC) solutions require high bandwidth, low latency components with CPU offloads to get the highest server efficiency and application productivity. The Mellanox ConnectX-3 and ConnectX-3 Pro network adapters for System x servers deliver the I/O performance that meets these requirements.

Mellanox's ConnectX-3 and ConnectX-3 Pro ASIC delivers low latency, high bandwidth, and computing efficiency for performance-driven server applications. Efficient computing is achieved by offloading from the CPU routine activities, which makes more processor power available for the application. Network protocol processing and data movement impacts, such as InfiniBand RDMA and Send/Receive semantics, are completed in the adapter without CPU intervention. RDMA support extends to virtual servers when SR-IOV is enabled. Mellanox's ConnectX-3 advanced acceleration technology enables higher cluster efficiency and scalability of up to tens of thousands of nodes.
