The modern data center faces a dual challenge: delivering the performance and agility required by AI, cloud-native, and mission-critical workloads—while also standing resilient against ransomware and advanced threats. Traditional perimeter defenses and bolt-on security layers are no longer enough.

This is why HPE Networking places security at the very heart of the fabric itself. With the HPE CX 10000 (CX10K), customers gain a distributed services switch that combines high-performance ToR switching with near line-rate microsegmentation, L4 stateful inspection, and DDoS protection built directly into the hardware.

Building on this foundation, HPE Networking has now introduced the CX 10040, a next-generation Distributed Services Switch (DSS) with 32 x 100 GbE and 6 x 400 GbE ports, designed to extend Security-First Networking into the era of AI and high-density workloads. Together, the CX10K and CX10040 provide a continuum of innovation—from today’s enterprise-scale data centers to tomorrow’s AI-driven infrastructures.

In contrast to many solutions that depend on software overlays or host-level agents—approaches that introduce additional complexity, consume compute resources, and enforce policies through in some cases one step removed from where traffic actually flows—the CX10K takes a different path. Microsegmentation, L4 inspection, and DDoS protection are embedded directly in the switch hardware, operating at the Top of Rack where workloads connect. This eliminates dependency on host resources or overlay constructs and enforces security closer to the VM and application traffic itself.

When combined with HPE VM Essentials (VME), these capabilities extend even further. VME provides a lightweight virtualization platform with full VM lifecycle management—provisioning, migration, high availability, and role-based governance—while natively integrating with Aruba CX Distributed Services Switch (CX10K) for microsegmentation. This means that segmentation policies defined in VME are enforced directly in the Top of Rack switch hardware, bringing security closer to workloads without the overhead of software overlays or host agents.

By aligning ToR enforcement with VMs, containers, and application boundaries, organizations gain consistent protection across environments. This approach reduces operational complexity and provides a clear foundation for Zero Trust, with security that is embedded, automated, and performance-resilient.

Microsegmentation, Reimagined

At the heart of this approach is the HPE Aruba CX 10000 (CX10K), the industry’s first distributed services switch that unites high-performance switching with hardware-accelerated security services. It delivers near line-rate microsegmentation, L4 stateful inspection, and DDoS protection—all at the Top of Rack (ToR).

Now, with the introduction of the HPE Aruba CX 10040, that vision extends even further. Offering 32 x 100 GbE and 6 x 400 GbE ports, the CX10040 brings the same distributed services architecture to the scale and bandwidth requirements of AI-driven, cloud-scale, and high-density data centers. With CX10K and CX10040, you can handle the demands of today’s workloads while building in the performance and security headroom your future applications will require.

Traditionally, microsegmentation relied on hypervisor controls or overlay software, which added complexity, consumed host resources, and enforced policy one step removed from application traffic. With HPE VM Essentials (VME) integrated into the CX Distributed Services Switch family, microsegmentation is now achieved directly at the Top of Rack, aligning enforcement with VMs, containers, and application boundaries.

If you’re navigating the uncertainty of the VMware ecosystem, HPE VM Essentials gives you a future-proof virtualization path. It lets you align security with application agility—without tying you to hypervisor-dependent overlays or kernel-bound agent models that limit flexibility.

From Detection to Containment: Closing the Loop on Ransomware

Zero Trust is more than access control—it is about designing for breach and minimizing its impact. In this model, the network fabric becomes a decisive control point. Through ecosystem integration, CX10K microsegmentation can now be combined with Zerto’s ransomware detection, orchestrated by OpsRamp. Zerto identifies suspicious activity by monitoring the statistical properties of data blocks. Using entropy analysis to measure data randomness, Zerto can detect when encryption is underway—since encrypted data exhibits a distinct, more random statistical distribution. A sudden spike in entropy serves as an early and reliable signal of ransomware in progress.

The workflow is illustrated below, showing how CX10K, Zerto, and OpsRamp work together to detect, isolate, and recover from ransomware events.

Once an event is detected, OpsRamp automation dynamically enforces isolation policies on the CX10K fabric. The affected workload is quarantined instantly, preventing lateral spread and buying critical time for response.

This tight integration of detection, orchestration, and network-level enforcement transforms ransomware from a business-halting crisis into a contained and recoverable event. By pairing Zerto’s journal-based recovery with CX10K’s hardware-embedded microsegmentation, organizations achieve both operational continuity and security confidence.

How It Works in Practice

This solution delivers value through tight integration across the stack, as shown in Figure 2. It creates an automated chain of defense that progresses through five steps:

1. Detection: Zerto monitors block-level changes and uses entropy analysis to identify encryption patterns characteristic of ransomware.
2. Alerting: When suspicious behavior is detected, Zerto generates an encryption detection alert.
3. Orchestration: OpsRamp ingests the alert and triggers a pre-defined automation workflow.
4. Policy Enforcement: Through lightweight scripts and API calls to the CX10K Policy Services Manager (PSM), OpsRamp dynamically updates segmentation policies, instantly isolating the compromised workload.
5. Recovery: With the threat contained, Zerto’s journal-based recovery rolls workloads back to a clean state, minimizing downtime and data loss.

This end-to-end flow ensures ransomware is not only detected, but also contained, remediated, and recovered from automatically—reducing response times from hours to seconds and preserving business continuity.

Security-First, Future-Ready

In today’s climate, resilience is not optional—it is the baseline expectation. Outages, ransomware, and shifting virtualization landscapes demand an infrastructure that is secure by design and agile by default.

By embedding advanced security services directly in the switch fabric, extending them through virtualization with VM Essentials (VME), and integrating with Zerto’s journal-based recovery orchestrated by OpsRamp, HPE Aruba Networking delivers an architecture purpose-built for enterprises that refuse to compromise on security or agility.

This is not about adding yet another layer of defense. It is about reimagining the network itself as the foundation of cyber resilience. With policy enforcement at the Top of Rack, microsegmentation aligned to applications, and automated ransomware containment, organizations gain the ability to minimize impact, accelerate recovery, and protect business continuity even under the most aggressive attack scenarios.

With CX10K, CX10040, VME, OpsRamp, and Zerto, you’re not just defending against ransomware—you’re strengthening the continuity of your applications, protecting your data, and reinforcing the trust your business depends on in a digital-first world.
