Chelsio T6 Dual Port 40G/50G/100GbE Adapter

The Chelsio T6 Dual Port 40G/50G/100GbE Adapter is a high-performance network interface card designed for next‑generation data centers. As part of the Terminator series, this PCIe Gen3/Gen4-ready adapter delivers a unified fabric over a single wire by simultaneously running multiple networking protocols. It is optimized for storage, virtualization, cloud computing, and HPC workloads, enabling converged networking that simplifies cabling, reduces TCO, and accelerates critical applications. Built to meet the demands of multi-tenant, hyperscale, and enterprise environments, the T6 combines robust throughput with low latency, high reliability, and flexible management across diverse OS and hypervisor platforms. Through hardware offloads and intelligent traffic handling, it helps intelligent data centers squeeze maximum value from server and storage infrastructure while supporting modern workloads like virtualization, containerization, and large-scale data analytics.

• Blazing-fast multi-protocol offload and scalable NIC architecture: The Chelsio T6 Dual Port 40G/50G/100GbE Adapter leverages advanced hardware offloads to move data with minimal CPU intervention. It supports concurrent protocol stacks, including iSCSI/TCP offload for storage, Fibre Channel over Ethernet (FCoE), and NVMe over Fabrics acceleration, along with virtualization offloads for SR-IOV and VM traffic. This combination delivers dramatically reduced CPU overhead, lower latency, and consistent throughput as workloads scale. With multiple transmit and receive queues and deep packet offload capabilities, administrators gain fine-grained control over performance characteristics for databases, analytics, and virtualized environments. The result is smoother application performance, improved VM density, and better server consolidation in dense data centers.
• Unified fabric on a single wire for storage, compute, and virtualization: This adapter is engineered to converge networking protocols across Ethernet onto a single, streamlined fabric. By running storage, compute networking, and virtualization traffic concurrently, it reduces cabling complexity and simplifies lifecycle management in modern data centers. The Terminator series enables consistent performance across diverse traffic types—VM migration, live backup, storage traffic, and data movement—without requiring separate adapters or NICs for each workload. This single-wire architecture supports hyper-converged infrastructure (HCI) and cloud deployments, delivering predictable latency and throughput at scale, while enabling easier upgrades, easier policy enforcement, and tighter coordination between servers, storage, and network fabrics.
• Broad OS and hypervisor compatibility with easy deployment: The T6 is designed for seamless integration with leading operating systems and virtualization platforms. It ships with optimized drivers for Linux distributions, Windows Server, VMware ESXi, Hyper-V, and other major hypervisors, ensuring fast, pain-free deployment and consistent performance. With extensive configuration options, administrators can tailor NIC features to match workload profiles, including RSS (Receive Side Scaling), multiple transmit/receive queues, and offload engines. The adapter supports hot-plug operation and robust error handling, minimizing downtime during maintenance and upgrades, while simplifying ongoing management in mixed environments that include bare-metal servers, virtual machines, and containerized workloads.
• Performance, latency optimization, and quality of service: The Chelsio T6 delivers ultra-low latency paired with high throughput—critical for latency-sensitive applications and high-velocity data paths. It provides multi-queue RSS to evenly distribute traffic across CPU cores, hardware offloads for virtualization, encryption, and data integrity, and QoS features to guarantee predictable performance for databases, VDI, analytics, and real-time services. This combination reduces CPU overhead, increases core utilization efficiency, and maintains stable performance even as workload diversity and density rise in modern data centers.
• Reliability, scalability, and efficient operation: Built for the rigors of dense data centers, the T6 emphasizes reliability with solid thermal management, power efficiency, and scalable PCIe connectivity to accommodate growing workloads. Dual ports offer redundancy and flexible cabling for future expansion, while the architecture supports scalable throughput as network demands increase. The adapter integrates with server management and monitoring tools so operators can observe throughput, latency, and utilization in real time. Its energy-conscious design helps lower operating costs in hyperscale environments, where small efficiencies multiply across hundreds or thousands of servers.

How to install Chelsio T6 Dual Port 40G/50G/100GbE Adapter

• Power down the server and disconnect all cables. Ground yourself to discharge any static electricity before handling the card.
• Open the chassis and locate an appropriate PCIe slot with sufficient bandwidth for dual 40G/50G/100GbE operation. Remove the slot cover if needed and insert the Chelsio T6 card firmly into the slot; ensure it is seated straight and fully engaged.
• Reconnect power and boot the server. If the system does not automatically detect the card, enter BIOS/UEFI to confirm the PCIe slot is enabled and properly configured for PCIe Gen3/Gen4 operation.
• Install the latest drivers and management software from Chelsio or the vendor repository that matches your operating system and hypervisor version. Follow on-screen prompts to complete the driver installation and restart if required.
• Configure the NIC settings according to workload requirements. Enable desired offloads (e.g., iSCSI/TCP offload, SR-IOV, RSS), set up network teams or bonds for redundancy, and apply QoS policies if supported by your network environment. Verify link status and performance through diagnostic tools and benchmarks.
• Connect the appropriate cables (QSFP28 fiber or DAC) to your network switch or storage array. Confirm negotiated link speeds and duplex settings, and perform a basic connectivity test using ping, iPerf, or vendor-provided test utilities to ensure stable, high-throughput operation.
