Supermicro X11DAi-N Workstation Motherboard - Intel C621 Chipset - Socket P LGA-3647 - Extended ATX

The Supermicro X11DAi-N is a high-performance, dual-socket workstation motherboard built around the Intel C621 chipset and the Socket P LGA-3647 platform. Engineered for demanding enterprise workloads, this Extended ATX board delivers exceptional multi-processor computing power, expansive memory capacity, and flexible I/O to power virtualization, data analytics, HPC, and memory-intensive applications. Designed for reliability and scalability, the X11DAi-N combines enterprise-grade features with ease of deployment in data centers, research labs, and professional studios, making it a foundational cornerstone for professional-grade workstations and server-class deployments.

• Dual Xeon Scalable processing for unrivaled compute power. The X11DAi-N supports two Intel Xeon Scalable processors, delivering substantial multi-core performance and parallel processing capabilities. This configuration is ideal for virtualization hosts, databases, simulation workloads, and AI/ML pipelines that demand sustained throughput across multiple cores and threads. With the powerful combination of two CPUs, users can allocate isolated resources, run dense virtual environments, and accelerate batch processing without compromising stability or reliability.
• Massive memory capacity for memory-intensive workloads. Equipped with 24 DIMM slots, the board supports up to 3TB of DDR4 memory at 2666MHz with ECC protection. This expansive memory footprint is particularly beneficial for in-memory databases, large-scale virtualization, scientific computing, and real-time analytics. ECC memory helps detect and correct common data errors, improving data integrity and system stability during long-running workloads.
• Versatile PCIe I/O and expansion for GPUs, accelerators, and storage. The X11DAi-N provides abundant PCIe expansion opportunities to house GPUs for rendering or AI inference, high-speed adapters for networking, NVMe storage controllers, and other accelerators. The PCIe architecture supports high-bandwidth devices, enabling you to design a tailored system for your workload—whether you’re building a powerful render node, a densely virtualized server, or a data-analytic powerhouse.
• Robust management and security features for data center-grade operations. Integrated IPMI 2.0 with remote management capabilities enables remote monitoring, firmware updates, and KVM over IP. This reduces on-site maintenance and accelerates troubleshooting, while secure management options help protect firmware integrity and system configuration across deployment fleets. IT teams benefit from proactive health monitoring, event logging, and rapid recovery workflows.
• Enterprise-grade reliability with flexible storage and deployment options. The Extended ATX design supports a broad array of storage configurations, including SATA and SAS controllers, to accommodate diverse data requirements. Built to endure continuous operation in demanding environments, the X11DAi-N is an optimal choice for data centers, HPC racks, and professional workstations that need dependable performance, scalable I/O, and straightforward integration into existing IT infrastructures.
