Supermicro Add-on Card AOC-NXB-10GCX4

Supermicro's AOC-NXB-10GCX4 is a 10GbE, low profile PCI Express card with a native CX4 copper interface based on NetXen's NX2031. It is a high performance layer 2 NIC that can support offload of TCP/IP, iSCSI and RDMA protocols, significantly improving throughput of servers, server appliances and storage platforms, while reducing host CPU utilization. This allows overall system performance to scale dramatically.

The AOC-NXB-10GCX4 is a highly integrated, fully programmable Intelligent NIC device designed to offload and accelerate processing tasks. It provides the datacenter with an extremely cost effective, low latency, 10GbE solution that is ideally suited for small clusters and in-rack connectivity.


Key Features

Intelligent NIC designed to offload and accelerate processing tasks Low profile PCIe card enables usage in all server form factors including 1U rack servers Cost effective deployment via CX4 infrastructure Increased application throughput and reduced host CPU utilization due to complete protocol offload Reduced cabling and support costs with a single 10GbE link Optimal use of I/O slots - 10GbE with multiple protocol support Performance scalability for consolidated server environments Reduced latency - better system performance for clustered applications Investment protection - full programmability allows changes to protocols to be implemented in F/W avoiding expensive hardware upgrades Future proofing - 10GbE with the flexibility of field upgradeable features - new features can be added via F/W upgrades in the field Improved reliability and error handling benefits of PCIe Common drivers across all Intelligent NICs in the family - reducing TCO
