Reshaping AI Infrastructure: HPE Closes Juniper Acquisition
HPE has completed its US$14bn acquisition of Juniper Networks, creating a networking vendor with US$7bn in annual revenue and establishing a direct competitor to Cisco across enterprise, data centre and service provider markets.
The transaction, which closed in July 2025, doubles HPE’s networking business and positions the company to address infrastructure challenges created by AI workloads. It also aims to bring together HPE’s enterprise networking capabilities with Juniper’s data centre and service provider expertise under a single organisation.
Rami Rahim, former CEO of Juniper Networks, now leads HPE’s combined networking business as President and General Manager of HPE Networking.
“Today begins a new era for HPE – we are now at the epicentre of the transformation of IT, where AI and networking are converging,” says Antonio Neri, President and CEO of HPE.
“In addition to positioning HPE to offer our customers a modern network architecture alternative and an even more differentiated and complete portfolio across hybrid cloud, AI and networking, this combination accelerates our profitable growth strategy as we deepen our customer relevance and expand our total addressable market into attractive adjacent areas.”
Targeting AI infrastructure bottlenecks
The combined entity plans to address infrastructure limitations that emerge when organisations deploy machine learning workloads on networks designed for different requirements.
Training large language models (LLMs) requires moving terabytes of data between hundreds of GPUs, creating demands that often exceed the capacity of existing enterprise networks.
Most enterprise networks were built when applications followed predictable patterns and data movement occurred in structured flows and now they are struggling with the resource demands and traffic patterns generated by AI applications, forcing companies to implement expensive upgrades or complex workarounds.
“HPE and Juniper have a unique opportunity to disrupt the networking industry at the most important and relevant time,” says Rami. “Together, we'll be able to provide customers and partners with a secure network that is purpose-built with AI and for AI.”
The acquisition has now created a vendor with presence across multiple market segments previously served by separate suppliers. HPE now competes with Cisco in enterprise wireless, data centre fabric, campus networking and wide area networks through a unified sales organisation.
HPE GreenLake integrates Juniper networking capabilities
HPE plans to incorporate the combined networking capabilities into its GreenLake cloud services platform, creating what the company describes as cross-domain operations through a single interface.
This integration addresses challenges faced by companies implementing hybrid cloud strategies, where applications distributed across on-premises data centres and public clouds require consistent performance and security policies.
- HPE’s $14 billion Juniper acquisition doubles its networking revenue to $7 billion annually
- Combined networking division expected to contribute over 50% of HPE’s total operating income
- Deal creates competitor spanning enterprise, data centre and service provider markets
Combining the platform aims to provide consistent interfaces regardless of where applications run, simplifying hybrid cloud implementation by unifying management across different components.
GreenLake will serve as the foundation for delivering these integrated capabilities to customers.
Companies implementing hybrid cloud architectures face specific networking challenges when connecting distributed applications across on-premises data centres and public clouds. To mitigate this, HPE hopes integrating Juniper’s data centre expertise with its networking products will provide more unified policy management and consistent operational interfaces.
Driving HPE revenue growth
The combined networking division is expected to contribute over 50% of HPE’s total operating income, representing a significant shift for the company.
It speaks to the scale of how the data centre networking market is booming, as AI infrastructure investment continues to surge.
The acquisition also puts pressure on other networking vendors to either expand their portfolios or accept smaller market positions. Cisco remains the largest networking vendor by revenue, but now faces a competitor with broader market reach and increased financial resources for research and development.
HPE is now serving enterprise, data centre and service provider customers through a unified organisation, potentially simplifying procurement and support processes for customers operating across these segments.
“The network is the core foundation of a hybrid IT infrastructure, and the world today requires a strong innovator at scale,” says Antonio. “Our acquisition underscores the imperative of networking as we enter a new era in IT defined by the unprecedented convergence of networking, hybrid cloud and AI.
“Whether building the right network to pursue strategic AI initiatives or using AI to optimise network ops, customers will benefit from both HPE Aruba Networking and HPE Juniper Networking products and solutions that are part of a next-generation technology architecture to deliver the power, performance and ease of management that AI requires.”
