Leading OEMs Embrace 21-Inch Open Rack Designs
Dell and HPE have embraced the modular server design architecture proposed by the Open Compute Project, known as the Data Center Modular Hardware System (DC-MHS). They are at the forefront of developing this standard, aligning their design work with Open Compute Project principles. Omdia’s analysis of Dell’s product roadmap suggests that up to 90% of new server shipments could adopt the 21-inch Open Rack Enclosures, with Dell focusing on rack-level compute and storage solutions.
AI Servers Drive Demand for Advanced Rack Infrastructure
Rack-scale AI-optimized designs feature numerous copper connectivity cables, direct-to-chip liquid cooling capabilities, and robust power distribution systems, all benefiting from the spacious 21-inch racks.
Cloud Providers Propel Adoption of 21-Inch Racks
Major cloud service providers like Microsoft, Amazon, Meta, Google, and others have standardized on 21-inch racks. ODMs servicing these providers confirm a sustained investment trend, with companies like Wiwynn experiencing strong demand for AI servers, necessitating expansion of manufacturing facilities to meet orders through 2027.
21-Inch Open Rack Enclosures Offer Engineering Advantages
The wider 21-inch Open Rack Enclosures provide improved airflow for efficient thermal management, accommodating larger fan arrays. These racks also facilitate future upgrades by allowing component replacements while maintaining I/O compatibility, ensuring compatibility with more powerful processors down the line.
Growth in the Data Center Rack Market is Accelerating
The industry shift towards 21-inch Open Rack Enclosures is expected to drive accelerated shipments and revenue growth, particularly as cloud providers adopt rack-scale server designs. This transition will lead to the phase-out of 19-inch EIA-310 Rack Enclosures, with data center rack shipments projected to outpace server growth for the first time in years.
