Description

The Chelsio T520-CR is a high-performance dual-port 10 Gigabit Ethernet Unified Wire Adapter, built around Chelsio's powerful Terminator T5 Application Specific Integrated Circuit (ASIC). This adapter is engineered to provide exceptional throughput and low latency, making it suitable for the most demanding enterprise and data center environments. The 'Unified Wire' concept signifies its ability to handle multiple network protocols and storage traffic types with significant hardware offloads, reducing CPU utilization and improving overall system efficiency. Key to the T520-CR's performance are its robust offload engines. It supports hardware offloads for TCP/IP processing, iWARP (Internet Wide Area RDMA Protocol), iSCSI, and Fibre Channel over Ethernet (FCoE). This extensive offload capability allows the adapter to handle complex networking tasks directly in hardware, freeing up the host CPU for application processing and enabling higher server density and performance. The adapter features a PCIe Gen 3.0 x8 interface, providing ample bandwidth to support its dual 10GbE ports. It utilizes SFP+ connectors, allowing for flexible deployment with various compatible optical transceivers. The Chelsio T520-CR is an ideal solution for applications requiring high-speed networking, storage consolidation, and efficient data transfer, such as high-performance computing, financial trading, and large-scale storage solutions.
