Dell's data center switches are high-performance network switches designed for modern data centers. They provide the foundation for scalable, automated, and secure networking, helping you handle demanding workloads and drive business innovation.

Dell PowerSwitch delivers high-density, low-latency connectivity from 1GbE to 800GbE to eliminate network bottlenecks. Their open, standards-based architecture supports massive fabric scaling and seamless integration, ensuring your infrastructure can grow efficiently with your business demands.

The "-ON" (Open Networking) suffix indicates that the switch supports a choice of third-party operating systems, giving you the flexibility to build a network that fits your specific operational model.

The PowerSwitch Z-Series, particularly the Z9864F-ON, is engineered for high-performance data center spines and super-spines. It offers industry-leading 800GbE density and throughput to support the most demanding cloud, AI/ML, and large-scale enterprise workloads.

Dell PowerSwitch Layer 3 switches provide advanced routing capabilities to direct traffic efficiently across different network segments, which is critical for modern data center design. Many models in the S-Series offer flexible SFP+ ports for high-speed 10GbE fiber connectivity.

Yes, the Dell PowerSwitch E-Series includes multi-gigabit switches with 48-port configurations that support high-power PoE. These switches are ideal for powering devices like wireless access points, IP cameras, and VoIP phones.

A Top-of-Rack switch connects servers and storage within a single rack to the broader data center network, simplifying cabling and improving performance. The Dell PowerSwitch S- and Z-Series offers a range of 1 to 800 GbE switches that are perfectly suited for Top-of-Rack deployments, providing high-density connectivity and low latency.

Dell's data center switches like PowerSwitch provide the high-bandwidth, low-latency fabric essential for large data transfers in AI training and inference workloads. With support for up to 800GbE and advanced features, they ensure your network can keep pace with accelerated computing and storage.

Dell PowerSwitch incorporates a multi-layered security approach, including features like port security, access control lists (ACLs), Hardware Root of Trust features, Secure Boot, Trusted Platform Module TPM 2.0 and authentication protocols to safeguard your network. Open Networking models also support advanced security software to help you build a Zero Trust-ready architecture.

Yes, PowerSwitch is designed for modern, automated environments and support a wide range of management tools. They offer standard CLI, REST APIs, and support for automation frameworks like Ansible, allowing for seamless integration into your existing DevOps and NetOps workflows. They also offer SmartFabric Manager for SONiC, enabling simplified deployment, orchestration, monitoring and life cycle management of SONiC fabrics through a single pane of glass.
