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

The Chelsio T580-LP-CR is a high-performance network adapter designed for demanding data center and enterprise environments. Leveraging the advanced Chelsio T5 (Terminator 5) processor, this low-profile PCI Express 3.0 x8 card delivers exceptional throughput and offload capabilities, making it ideal for virtualized and high-bandwidth applications.

Advantages

With support for 100 Gigabit Ethernet per port, the T580-LP-CR provides blazing-fast connectivity for mission-critical workloads. Its comprehensive offload engine (TOE, iSCSI, FCoE) reduces CPU overhead, while RDMA over Converged Ethernet (RoCEv1/v2) enables low-latency data transfers. Virtualization features like SR-IOV, NPAR, VXLAN, NVGRE, and GENEVE ensure efficient resource sharing in cloud and virtualized environments.

Suitable for

• Data centers requiring high-speed 100GbE connectivity
• Enterprise servers running virtualized workloads (VMware, Hyper-V, KVM)
• High-performance computing (HPC) clusters
• Storage networks (iSCSI, FCoE, NVMe over Fabrics)
• Financial trading and real-time analytics platforms
