IBM 81Y8021 Fiber Optic Network Card

The Chelsio dual-port and quad-port Unified Wire adapters for IBM Intelligent Cluster and IBM iDataPlex are 10 Gigabit Ethernet adapter with PCI Express host bus interface optimized for cloud computing, HPC, virtualization, storage, and other data center applications. These adapters are based on fourth-generation (T4) technology from Chelsio, provide the highest 10GbE performance available, and dramatically lower host-system CPU communications overhead with on-board hardware that offloads TCP/IP, iSCSI, FCoE, and iWARP RDMA processing from its host system. As a result, the server can achieve increased bandwidth, lower latency, and lower power consumption.
