The Lenovo ThinkSystem DM Series 100Gb iWARP 2 Port Ethernet Card is engineered to deliver extraordinary bandwidth and reliability for modern data centers. This dual-port 100 Gigabit Ethernet adapter is built to meet the demanding needs of high-performance computing, virtualization, and large-scale networking without spiraling hardware costs. By combining extremely high throughput with iWARP offload capabilities, this card reduces CPU overhead, minimizes latency, and accelerates data-intensive applications—from AI inference and analytics to in-memory databases and cloud-native services. When deployed in ThinkSystem DM Series servers, it enables scalable, fabric-ready networking that can grow with your workloads, ensuring your infrastructure remains responsive under peak demand while maintaining an efficient total cost of ownership. In environments where latency matters as much as bandwidth—datacenters, hyperscale clusters, and enterprise data floors—the DM Series 100Gb iWARP card provides a dependable foundation for fast, predictable connectivity, robust management, and straightforward expansion.

  • Ultra-high throughput and low latency: With 2 x 100 GbE iWARP-capable ports, this adapter delivers line-rate performance for latency-sensitive workloads. It accelerates data transfers across virtual machines, containerized services, databases, analytics pipelines, and AI workloads by offloading memory-to-memory operations from the CPU, reducing interrupt storms, and keeping applications responsive even under heavy load.
  • Hardware offload and CPU efficiency: The iWARP RDMA offload engine on this card minimizes CPU overhead, enabling higher virtual machine density, smoother multi-tenant environments, and improved overall server efficiency. By handling RDMA operations at the adapter level, users experience lower latencies, faster data access, and a more predictable performance profile for demanding enterprise applications.
  • Seamless Lenovo ThinkSystem integration: Designed and tested for ThinkSystem DM Series servers, this Ethernet card is optimized for Lenovo management ecosystems, including Lenovo XClarity and ThinkSystem Manager. The integration enables streamlined firmware updates, health monitoring, and centralized configuration across an expanding network fabric—helping IT teams reduce operational complexity while maintaining maximum uptime.
  • Flexible connectivity and scalable design: The two 100 GbE interfaces commonly utilize QSFP28 connectors, enabling dense, scalable cabling for data center networks. The card supports network fabric features such as NIC teaming, link aggregation, and RDMA-aware software stacks, empowering you to build resilient, scalable networks that can grow with your business needs without requiring a complete network overhaul.
  • Reliability, manageability, and lifecycle support: Built for enterprise environments, the DM Series 100Gb iWARP card emphasizes reliability, robust error handling, and straightforward lifecycle management. In addition to standard protection features, Lenovo’s supported ecosystem helps ensure firmware compatibility across your data center, reducing maintenance risk and providing solid vendor support for critical networking upgrades.

How to install Lenovo ThinkSystem DM Series 100Gb iWARP 2 Port Ethernet Card

  • Power down the server, unplug power, and ground yourself to prevent static discharge; remove the chassis cover to access the server’s PCIe slots.
  • Identify an appropriate PCIe slot with sufficient bandwidth (typically a PCIe x8 or higher slot) in the ThinkSystem DM Series server based on your hardware configuration and expansion plans.
  • Line up the card with the chosen PCIe slot and firmly insert it until the retention latch engages. Ensure the card is seated evenly and secured.
  • Attach the QSFP28 network cables to the card’s connectors, making sure to follow proper orientation and avoid excessive cable bending to preserve signal integrity.
  • Secure the card with the slot screw and reseal the chassis. Reconnect power and boot the server.
  • Enter the system firmware or BIOS post-boot to verify that the new NIC is recognized and enumerated by the system.
  • Install or update the required drivers and firmware through Lenovo XClarity Administrator or ThinkSystem Manager, following the on-screen prompts or your organization's standard imaging process.
  • Configure the network settings in the operating system or software-defined networking stack (MTU, VLANs, NIC teaming, SR-IOV if supported, and RDMA parameters) to align with your data center fabric and performance goals.

Frequently asked questions

  • What is the Lenovo ThinkSystem DM Series 100Gb iWARP 2 Port Ethernet Card?
    The card is a dual-port 100 GbE network adapter with iWARP RDMA offload designed for Lenovo ThinkSystem DM Series servers. It provides high-bandwidth connectivity with low latency, enabling more efficient data center networking and improved performance for virtualization, analytics, and memory-intensive workloads.
  • Which workloads benefit most from iWARP RDMA on this card?
    iWARP RDMA offloads memory-to-memory transfers from the CPU, delivering lower latency and higher throughput for virtualization platforms, large-scale databases, in-memory processing, HPC workloads, and real-time analytics in dense server environments.
  • How do I manage and monitor the card?
    Management is streamlined through Lenovo’s XClarity Administrator and ThinkSystem Manager. These tools provide firmware update orchestration, health monitoring, configuration management, and integration with your existing data center monitoring framework.
  • Is this card hot-swappable?
    In supported ThinkSystem DM Series servers, the card is designed for enterprise reliability, including hot-swap maintenance options. Always consult your server’s hardware maintenance guide for exact hot-swapping procedures and compatibility.
  • What cabling and switches are required for 100 GbE operation?
    The card uses QSFP28 connectors for 100 GbE connectivity. Ensure your network fabric—including switches and cables—supports 100 GbE and is configured to leverage iWARP RDMA features for best results.

Fairly priced but the finish leaves something to be desired
Color: Black Walnut
This wrist rest looks very nice, but I'd give the finish of the wood a C. There are a few rather rough patches, one that feels like it will develop into splinters eventually if it's not refinished. I'm using it for now, but I'm definitely going to refinish it at some point and it's inspired me to make my own wrist rests from scratch out of hardwood. I gave this two stars because it's very pretty and it's fairly comfortable to use. The wood used is pretty expensive, so I'd say that the price of this item is rather fair. I just wish they put a better finish on materials that are so nice.

Built to Last
Color: Black
When purchasing little practical and intentional pieces... it's easy to pick something of lesser value. Looking at all other styles and options, you see buttons and Velcro and magnets and they look enticing. But at the end of the day, you want the satisfaction of knowing you made the right choice. Pay a little extra and get what you want. This little tray will be in your possession for years to come. It's clean and sturdy and classy. Maybe a 2-tone color palette would be a nice option for future builds.

Light Weight CarryAll
Color: Brown
Being Retired I'm always home and throughout my day i settle in different spots in my house to do different tasks or activities like exercise. I found myself either carrying a bunch of small things from room to room or having to walk all the way back to my previous, I call "perch," to fetch my phone, reading glasses, stylus, pillbox, tumbler of tea, and yes, pen & paper! Now with this catch all, I just load it up in seconds and I'm good to go!!!
