Dell has spent years positioning itself at the center of the shift from individual servers to fully integrated racks for AI factories. At Dell Technologies World 2026, the company unveiled expanded PowerRack portfolio, combining compute, networking, and storage into a single rack-scale system.
Arun Narayanan, senior vice president for compute and networking product management at Dell, emphasized that rack-level rethink is unavoidable given skyrocketing power density. He noted that two years ago the largest rack was 80 kilowatts; today's racks reach 235 kilowatts, and future racks will hit one megawatt.
Dell has retooled its cooling strategy moving from hybrid to fully liquid-cooled architecture. The company is exploring two-phase cooling and immersion cooling for future requirements. While not every enterprise can retrofit for direct liquid cooling, Dell continues to offer air-cooled portfolio.
According to Alison Biers, global marketing senior director, Dell ranked No. 1 among rack-scale infrastructure providers in 2025 by IDC. The PowerRack delivers factory-tested, turnkey system that goes from delivery to full production in about six hours.
On networking, Narayanan described SONiC as the future operating system for AI infrastructure. He compared SONiC to Linux, saying it will transform AI networking with lightweight, high bandwidth, low latency network operating systems.
