The HPE FlexFabric 12900E 24-Port 400GbE QSFP-DD Type H2 Module is a high-density, performance-driven expansion module designed for the heart of modern data centers. Built to support virtualized environments, private and public clouds, and the evolving needs of large-scale interconnects, this module delivers the bandwidth, scalability, and reliability required by today’s demanding workloads. When deployed in the HPE FlexFabric 12900E switch series, it unlocks a scalable fabric that can accommodate accelerating workloads, storage traffic consolidation, and microservices architectures with ease. This module is engineered to maximize efficiency in spine-leaf topologies, enabling fewer, more productive hops between racks while maintaining deterministic latency and predictable performance.

Designed for resilience and long-term value, the 12900E series emphasizes modularity, intelligent fabric management, and robust compute-to-network convergence. The Type H2 QSFP-DD module integrates seamlessly with HPE’s software-defined networking stack, delivering advanced traffic engineering, QoS, and telemetry that empower IT teams to orchestrate multi-tenant environments with confidence. The result is a flexible, future-proof foundation that accelerates cloud initiatives, simplifies network operations, and reduces total cost of ownership through consolidated cabling, streamlined upgrades, and centralized management.

Whether you’re building a private cloud, scaling a public cloud footprint, or accelerating a data center modernization project, the HPE FlexFabric 12900E 24-Port 400GbE QSFP-DD Type H2 Module helps you achieve higher throughput with lower latency. The module’s high-density design reduces space requirements while delivering the performance needed for real-time analytics, high-frequency trading, AI/ML inference, and other bandwidth-intensive workloads. In practice, this means fewer bottlenecks, improved application response times, and greater headroom to expand capacity as your data center grows. The module also supports virtualization-friendly features, enabling efficient work consolidation and streamlined network isolation to meet compliance and security requirements in multi-tenant deployments.

  • Ultra-high-density 24 x 400GbE QSFP-DD Type H2 ports deliver immense backbone bandwidth and collapse multiple adjacency links into a single, scalable fabric. Ideal for spine-leaf architectures and high-performance interconnects, this module enables aggressive growth without sacrificing manageability or efficiency.
  • Low latency and high-throughput performance support demanding workloads and real-time applications. The module’s design prioritizes fast forwarding, consistent throughput, and predictable timing, which is essential for virtualization, database clustering, and data-intensive analytics pipelines.
  • Advanced buffering, QoS, and traffic engineering empower precise control over service levels. With intelligent queueing, congestion management, and policy-based routing, you can isolate workloads, guarantee bandwidth for mission-critical apps, and optimize the data plane for multi-tenant environments.
  • Modular, hot-swappable design for high availability minimizes downtime and maintenance windows. The Type H2 module is designed for rapid replacement in live environments, with secure seating, latch mechanisms, and compatibility with standard data center operating procedures.
  • Reliability, security, and seamless management integration are built into every aspect of the module. From robust error detection and fault containment to telemetry-enabled monitoring and firmware compatibility with HPE management tools, this module supports proactive operations and safer, streamlined lifecycle management in enterprise-scale deployments.

How to install HPE FlexFabric 12900E 24-Port 400GbE QSFP-DD Type H2 Module

  • Prepare the environment by following data center best practices for hot-swappable components, including ESD precautions and ensuring the switch supports hot-swapping for the targeted module slot.
  • Identify the correct module slot in the HPE FlexFabric 12900E chassis. Verify that the slot supports a 400GbE QSFP-DD Type H2 module and that any required firmware prerequisites are met.
  • Power down the path where required or follow hot-swap procedures if your data center policy permits. If performing a hot swap, carefully release the retention latch and disengage the existing module, avoiding contact with sensitive connectors.
  • Align the new 24-port QSFP-DD Type H2 module with the slot connectors and firmly seat it into place until the latch engages securely. Gently verify that the module is seated evenly and locked.
  • Reconnect any cables to the QSFP-DD ports, ensuring clean, strain-free connections. After installation, power up (if needed) and access the switch management interface to confirm module detection, link status, port counts, and health indicators. Run a quick verification test to confirm expected throughput and latency characteristics.

A must have for wildlife lovers
Format: Paperback
Wow! What an excellent and thorough compilation of scat and tracks. Nice reference for when you take pics and bring the image back to the book for comparison. Also, great information about tracking.

Good but index needs improvement
Format: Paperback
This is a good, comprehensive guide to tracks and sign. However, there is no index of where to find each family, so in order to find a species you have to flip through the entire book looking for the right page. This makes it annoying to use if you are trying to look up information on a particular species or family.

This is a very useful field manual for those interested in detailed traking methodology.
Format: Paperback
I spent many years as interpreter and ranger for the Colorado State Park System, now called CPW—Colorado Parks and Wildlife. We were annually tasked with surveying a given species' presence, density, and range in the park system and surrounding areas. Detailed field manuals were critical to the accuracy of our work, and HOW I WISH I HAD THIS BOOK DURING THAT PART OF MY CAREER. There are few other books I've come across providing detailed, yet very accessible information on how trail sign reflects animal behavior across different conditions, landscapes, and seasons (both weather seasons and mating seasons). One particular aspect of this book I found significantly intriguing was the section on predation—how does a mountain lion take down a mule deer vs. how wolves bring one down. The locations on a prey animal where a certain predator is most likely to attack, showing illustrations, is a remarkable piece of work, and there authors are clearly masters of interpreting tracks and sign! If you want learn about how mammals behave in their native environment, adding this book to your field manual packet will greatly expand your horizons! Busy it, read it, and get outside! Thank you Mr. Elbroch and Mr. McFarland for adding to the wildlife canon!

Great book and very useful tool to have
Format: Paperback
I had the older edition and lived it, but someone at my last job *borrowed* it and I never saw it again. This edition sends even better than the last, and I have that one five stars. Great pictures and the number of species covered means it's good in at least all states I've worked in.

Simply unputdownable
Format: Kindle
B N William’s field guide is fascinating. The book uncovers the bizarre reality beneath the polished propaganda of the Second World War, exploring the wonderfully weird truths where the line between brilliant innovation and sheer insanity vanishes completely. Every unusual piece of information has been verified using official declassified archives. I loved the story of Wojtek, a Syrian brown bear, who became a beloved and legendary figure, known for his unique story as an enlisted soldier. Read many more such stories and episodes in this book. You will enjoy them thoroughly.
