## Summary description

Chelsio T580-LP-CR is an internal wired network card with a fiber interface supporting up to 40,000 Mbit/s. It connects via PCI Express host interface and is intended for high-speed server and workstation networking, low-latency data transfer, and storage or virtualization environments requiring 40 Gbit/s fiber connectivity.

## Long description

Chelsio T580-LP-CR is an internal dual-port fiber network card that delivers up to 40 Gbit/s per port over a PCI Express host interface. Designed for servers and workstations, this 40 Gigabit Ethernet adapter provides high-bandwidth wired connectivity for data center, storage and virtualization environments requiring low-latency, high-throughput fiber links.
Advantages
The card integrates Chelsio’s fifth-generation T5 architecture and a PCI Express host connection to reduce host CPU overhead by offloading TCP/IP, iSCSI, FCoE and iWARP RDMA processing to on-board hardware. This offload capability results in higher effective bandwidth, lower latency and improved system efficiency without increasing host CPU utilization. The dual-port fiber design supports consolidated networking and storage traffic over a single adapter, enabling denser server configurations and simplified cabling.
Suitable for
High-performance computing (HPC) clusters and compute nodes
Virtualization hosts and hyper-converged infrastructure
Storage servers and SAN front-ends requiring fast fiber links
Cloud and data center network uplinks
Key specifications
Interface: PCI Express host interface (PCIe Gen3 compatible)
Connectivity: dual fiber ports supporting 40 Gbit/s links
Throughput: up to 40,000 Mbit/s per port
Protocol offload: hardware offload for TCP/IP, iSCSI, FCoE and iWARP RDMA
Form factor: low-profile internal adapter suitable for server/workstation PCIe slots
How to use
Install the Chelsio T580-LP-CR into an available PCI Express slot following your server or workstation hardware guidelines, ensuring the system is powered down and grounded during installation. Connect fiber transceivers and optical cabling to the card’s fiber ports configured for 40 Gbit/s operation. Install the appropriate Chelsio drivers and firmware for your operating system, then configure network settings, link aggregation or storage protocols as required by your environment. Verify link status and performance through system management tools and vendor-provided utilities.
Usage recommendations
For optimal performance, use compatible 40G fiber transceivers and multimode or single-mode fiber as specified by your network design, keep drivers and firmware up to date, and enable protocol offloads where supported by your operating system and applications to minimize host CPU load and maximize throughput.
