Chelsio T520-CR Adaptador de red Dual Port 10GbE SFP+ PCIe 3.0 x8

The Chelsio T520-CR is a high-performance dual-port 10 Gigabit Ethernet network adapter designed for data centers and enterprise environments. Featuring the Chelsio T5 (Terminator 5) ASIC, it delivers aggregate throughput of 20 Gbps and supports advanced offload engines including TCP/IP Offload Engine (TOE), iSCSI, FCoE, and RoCE. The adapter is ideal for virtualized environments with SR-IOV and NPAR support, and it is compatible with major operating systems such as Windows, Linux, FreeBSD, VMware ESXi, and Citrix XenServer.

Advantages

With its low-profile, half-height PCIe 3.0 x8 form factor, the T520-CR fits into a wide range of servers and workstations. The dual SFP+ ports provide flexible connectivity for 10GbE networks, while hardware offloads reduce CPU overhead and improve application performance. Support for NVMe-oF and RDMA over Converged Ethernet (RoCE) enables low-latency storage and high-performance computing workloads.
