1. H3C Named a Representative Vendor in Gartner's 2026 Market Guide for Data Center Switching

On March 16, 2026, Gartner published its 2026 Market Guide for Data Center Switching, recognizing H3C (New H3C Technologies) as a Representative Vendor. This follows H3C's inclusion in Gartner's Magic Quadrant for Data Center Switching in 2025, marking back-to-back recognition from one of the industry's most closely watched research firms.

The report notes that the global data center networking market is undergoing a structural shift driven by AI growth, splitting into two distinct tracks: general-purpose networks focused on automation and reliability, and AI networking architectures tailored for large-scale GPU clusters requiring extreme bandwidth, ultra-low latency, and lossless transmission.

H3C is positioned across both tracks. On the AI networking side, the company's DDC (Diversified Dynamic-Connectivity) architecture uses cell-based switching to decouple GPUs from network cards, delivering 107% improvement in effective bandwidth over traditional networking and achieving performance comparable to InfiniBand - while remaining compatible with 400G and 800G access. On the software side, H3C continues to develop its Comware OS and AD-DC management platform for end-to-end automated management. H3C's data center solutions are deployed across government, finance, telecoms, and internet sectors globally, with international deployments at UNICON in Kazakhstan and U-NEXT in Japan among its notable references.

2. H3C Launches the S9828-128EP 800G AI Switch at the 9th Future Network Development Conference

The 9th Future Network Development Conference, themed "Global Networking, Winning the Future," was recently held in Nanjing, bringing together chairs of the Internet Research Task Force (IRTF), academicians from the Chinese Academy of Sciences and Chinese Academy of Engineering, and top global networking experts. H3C used the occasion to unveil its next-generation 800G AI computing switch - the H3C S9828-128EP.

The S9828-128EP is built around an industry-leading 102.4T switching chip, features a compact 4RU form factor, and supports up to 128 full-speed 800G OSFP ports. H3C claims the product delivers across-the-board improvements in performance, latency, energy efficiency, and operations. It is designed to simplify intelligent computing cluster architecture and reduce total cost of ownership (TCO) for large-scale AI training and inference deployments.

At the same conference, H3C Senior Vice President and President of the Network Product Line Qiao Yan put the company's networking philosophy plainly: an optimized network can boost overall computing capacity by more than 20-30%, making the network a critical variable - not just an overhead cost - in AI infrastructure investment.

3. HPE Exits H3C With a $1.4B Stake Sale, Doubling Down on Juniper and AI

Hewlett Packard Enterprise (HPE) has confirmed plans to divest its remaining 19% stake in H3C for approximately US$1.4 billion. The proceeds will be directed toward reducing the leverage taken on from HPE's landmark $14 billion acquisition of Juniper Networks in late 2025. The move formally ends a partnership between HPE and H3C that stretched back over two decades.

With the Juniper integration now its central focus, HPE is repositioning as an AI-native networking company, leveraging Juniper's Mist AI platform across its campus, branch, and data center portfolio. Analysts note that geopolitical tensions between the US and China have also accelerated HPE's strategic retreat from the Chinese market.

For H3C, the exit clears the way for its parent company Tsinghua Unigroup (which holds roughly 81% of H3C through Unisplendour International) to set H3C's direction independently. H3C currently holds approximately 32.9% of China's Ethernet switch market and 30.9% of the enterprise router market (IDC data), and has ranked first in China's enterprise WLAN market for fifteen consecutive years.

4. IDC 2026: AI Networking Adoption Stalls, Yet 89% of Data Centers Plan Bandwidth Expansion

The 2026 IDC AI in Networking Special Report, published just days ago, delivers a candid assessment: despite sustained organizational intent, enterprise AI adoption in networking has barely moved over the past 18 months. Organizations that were at the "selective use" stage have stayed there. "2026 is when organizations find out if AI in networking delivers real operational impact - or remains stuck in pilot mode," said IDC Research Director Mark Leary.

Three obstacles dominate: security concerns (also cited as the top AI use case), integration complexity with legacy systems, and a shortage of skilled talent. As a result, 81% of surveyed organizations say they are increasing spending on managed service providers to fill the gap.

Despite slow adoption, the pressure on physical infrastructure is real and immediate. 89% of data centers expect to increase bandwidth by at least 11% within the next year, driven by AI workloads, with cloud connectivity bandwidth projected to grow by an average of 49%. This creates direct demand for high-performance switching and routing hardware - the core of H3C's enterprise portfolio. IDC's prescription for network leaders: target high-impact use cases first, shift from reactive to proactive operations, and lean on external expertise where internal resources are thin.

5. REDnote and H3C Complete the World's First Commercial DDC Architecture AI Cluster Deployment

Chinese social platform REDnote (Xiaohongshu) has partnered with H3C to complete the world's first large-scale commercial deployment of an AI computing network cluster based on the DDC (Diversified Dynamic-Connectivity) architecture - a milestone that moves DDC from lab validation into production-grade infrastructure.

REDnote's requirements were unambiguous: achieve maximum load balancing, eliminate the configuration and maintenance complexity of traditional lossless networks, ensure the architecture could scale for future growth, and pass rigorous stability testing. After comparing multiple vendors, REDnote selected H3C's DDC solution as the foundation for its intelligent computing network.

H3C's DDC architecture achieves 100% network load balancing through cell switching technology, slicing data streams into standardized 512-byte segments and distributing them evenly across all available paths. Combined with VOQ+Credit intelligent traffic scheduling, the solution eliminates packet loss and head-of-line blocking - meeting the strict requirements of large model training and inference. Because this was the first DDC cluster deployment of its kind globally, the two teams jointly developed a new acceptance testing framework from scratch, drawing on traditional RoCE network standards and adapting them to DDC's lossless transmission characteristics.
