NAE isn’t just a reporting tool; it intelligently monitors network health, identifies anomalies, and can even trigger automated actions to resolve issues before they impact users. This proactive approach significantly reduces operational complexity and improves network uptime.

Power over Ethernet (PoE) Capabilities for a Clutter-Free Environment

Imagine powering your IP phones, wireless access points, security cameras, and other network devices directly through your Ethernet cables. That’s the magic of Power over Ethernet (PoE), and Aruba switches offer robust PoE capabilities, including PoE+ and even high-power PoE++ (802.3bt) for more demanding devices. This eliminates the need for separate power outlets and adapters, simplifying deployments, reducing cabling clutter, and saving energy thanks to features like Energy Efficient Ethernet (EEE).

High Availability and Scalability: Growing with Your Ambitions

Your network needs to grow and adapt with your business. Aruba switches are built for both. Features like Link Aggregation (LAG) and Redundant Power Supplies (RPS) ensure high availability, minimizing downtime and guaranteeing uninterrupted operation of critical services. For increased density and simplified management, many Aruba switches support Virtual Switching Framework (VSF) or Virtual Switching Extension (VSE), allowing multiple physical switches to operate as a single logical unit, enhancing resilience and simplifying upgrades. Whether you’re a small startup or a large enterprise, Aruba offers scalable solutions that allow your network to expand seamlessly as your needs evolve.

“In my two decades in network architecture, Aruba switches have consistently impressed with their blend of robust performance and intelligent automation. The AOS-CX operating system, especially with its Network Analytics Engine, transforms complex network operations into a streamlined, proactive experience. It’s not just about connecting devices; it’s about building a truly smart network.” – David Pham, Senior Network Architect at VGLan.
