This blog is co-authored by Petri Virsunen, Dell Technologies

Artificial intelligence (AI) is revolutionizing industries, driving innovation and reshaping the way we live and work. As organizations delve deeper into AI-driven initiatives, the need for robust and reliable networking infrastructure becomes paramount. Dell Technologies is at the forefront of this transformation, with groundbreaking innovations in networking technology. This blog explores how Enterprise SONiCDistribution by Dell Technologies4.4and the Dell PowerSwitchZ9864F-ON are revolutionizing AI fabrics and empowering generative AI (GenAI) initiatives.

Ethernet: The Backbone of AI Fabrics

SONiCSoftware for Open Networking in the Cloud continues to redefine the networking landscape, becoming the go-tooperating systemfor modern enterprises across various industries. With Ethernet emergingas the preferred backbone for AI fabrics, the demand for scalable high-performance networking solutions has never been greater.For AI fabrics serving as the backbone for GPU-to-GPU connectivity, Dell'OroGroup forecasts exponential growth, reaching $15.2 billionby 2027, with Ethernet taking up more than 30% of that footprint.

Enterprise SONiC Distribution by Dell Technologies 4.4: A Leap Forward

Enterprise SONiC Distribution by Dell Technologies 4.4. SONiC 4.4 brings substantial advancements in AI fabrics enablement. Dell provides a first in industry USGv6r1 compliant version of Enterprise SONiC Distribution¹. With feature additions such as RDMA over Converged Ethernet (RoCEv2), Dynamic Load Balancing with Adaptive Routing, and Enhanced User-defined Hashing, this release empowers organizations to leverage AI fabrics more effectively. RoCEv2 with Enhanced Hashing provides better packet entropy and optimal traffic distribution. Adaptive Routing with Dynamic Load Balancing ensures optimal utilization of links within an AI fabric, enhancing forwarding behavior and maximizing the performance and efficiency of network resources. Tail-latency sensitivity is one of the key characteristics of the AI fabrics as these AI workloads can't afford delays, so technologies like RoCEv2, Priority Flow Control (PFC), and Enhanced Transmission Selection (ETS) are essential. These features ensure smooth data flow, while Explicit Congestion Notification (ECN) helps manage and mitigate congestion in the network. Enterprise SONiC Distribution by Dell Technologies 4.4 introduces the Dell SmartFabric Manager, a comprehensive solution for fabric lifecycle management. With a single pane of glass interface, organizations can seamlessly manage AI fabrics along with storage, application fabrics and out-of-band management. This unified approach streamlines operations, enhances visibility and simplifies the management of complex network infrastructures.

Dell PowerSwitch Z9864F-ON: Engineered for AI Workloads

Today marks the release of PowerSwitch Z9864F-ON, a cutting-edge 800GbE platform. Featuring 64 ports of 800GbE connectivity and built on the latest Broadcom^® Tomahawk^™5 chipset, it is purpose-built for intensive compute and storage traffic and "elephant flows" typical for AI. In data center networking, AI workloads can involve transferring vast amounts of data between GPUs (Graphics Processing Units) for extended periods, which are essential for training complex machine learning models. As part of the Dell AI Factory offers, the PowerSwitch Z9864F-ON caters to the most demanding networking environments and scales to 8,000 GPU clusters in a two-tier CLOS topology.

The Importance of Networking in GenAI

In the era of GenAI where innovation is the currency of success, organizations must invest in networking solutions that can keep pace with the demands of AI-driven workloads. Every step in the AI workflow relies on a fast, reliable and resilient networking infrastructure. By leveraging cutting-edge technologies in Dell PowerEdge servers and Dell PowerSwitch Z9864F-ON, organizations can build robust Ethernet-based fabrics for their AI initiatives, unlocking new levels of performance, scalability and efficiency.

SONiC Distribution by Dell Technologies 4.4 represents a pivotal advancement in networking technology, empowering organizations to embrace the convergence of Ethernet and AI fabrics. With unparalleled scalability, performance and interoperability, SONiC enables enterprises to unlock new possibilities in AI-driven innovation while driving down costs and mitigating vendor lock-in.
