Chelsio T580-CR Network Adapter - PCIe 3.0 x8 - 2 x QSFP28 - 100GbE

The Chelsio T580-CR is a high-performance network adapter designed for data centers and enterprise environments requiring ultra-low latency and high throughput. Leveraging the Chelsio T5 (Terminator 5) controller, this adapter delivers up to 100 Gbps per port, supporting multiple Ethernet standards including 100GbE, 50GbE, 40GbE, 25GbE, 10GbE, and 1GbE. It features two QSFP28 ports and a PCI Express 3.0 x8 host interface, making it ideal for demanding applications such as high-frequency trading, cloud computing, and storage networking.

Advantages

With advanced offload capabilities including TCP/IP Offload Engine (TOE), UDP Offload Engine (UOE), iSCSI, FCoE, RDMA over RoCE, and NVMe-oF, the T580-CR significantly reduces CPU overhead, freeing server resources for application processing. Its support for virtualization technologies like SR-IOV, NPAR, VXLAN, NVGRE, and GENEVE ensures optimal performance in virtualized environments. The adapter also features Data Center Bridging (DCB) and Energy Efficient Ethernet (EEE) for enhanced network efficiency.
