Chapter 1: Introduction
1.1 Processor and Chipset Overview
Built upon the functionality and capability of the Intel Xeon Scalable-SP series and 2nd
Gen Intel Xeon Scalable-SP series processors with the Intel C621 chipset, the X11DPX-T
motherboard provides system performance, power eciency, and feature sets to address the
needs of next-generation computer users. This motherboard is ideal for high-performance
computing, I/O intensive storage and application, and industry embedded appliances.
The Intel C621 chipset provides Enterprise SMbus support and includes the following features:
• DDR4 288-pin memory support on Socket P
• Support for MCTP Protocol
• Support for Management Engine (ME)
• Support of SMBus speeds of up to 400KHz for BMC connectivity
• Improved I/O capabilities to high-storage-capacity congurations
• SPI enhancements
• Intel Node Manager 4.0 for advanced power monitoring, capping, and management for
BMC enhancement
• The BMC supports remote management, virtualization, and the security package for en-
terprise platforms
Note: Node Manager 4.0 support is dependent on the power supply used in the system.
Features Supported by Intel Xeon Scalable-SP Processors
Intel Xeon Scalable-SP processors support the following features:
• Intel AVX-512 instruction support to handle complex workloads
• 1.5x memory bandwidth increased to 6 channels
• Hot plug and enclosure management with Intel Volume Management Device (Intel VMD)
• Rich set of available IOs with increased PCIe lanes (48 lanes)
