Description
The Supermicro X8DAH+ motherboard, part of the 5500/5600 Series Processor platform, offers high-end system performance and advanced features for dual-processor/IOH-based systems, particularly well-suited for High-Performance Computing (HPC) and Cluster platforms. Powered by the 5520 chipset, it includes the IOH 36D (I/O Hub) and the ICH10R (South Bridge) to deliver exceptional performance and scalability.
The Intel QuickPath Interconnect (QPI) controller integrated into the 5520 platform replaces the Front Side Bus Technology, greatly enhancing system performance. The IOH-36D connects to each processor via independent QPI links, each providing 20 pairs of unidirectional differential lanes for high-speed data transfer. A full-width QPI link pair includes 84 signals.
The chipset supports up to 36 PCI Express Gen2 lanes, facilitating peer-to-peer read and write transactions. It offers a variety of RAS (Reliability, Availability, and Serviceability) features, including memory interface ECC, error correction, and memory mirroring.
The Supermicro X8DAH+ motherboard boasts impressive features like four processor cores in each processor with 8MB shared cache, two full-width Intel QPI links with up to 6.4 GT/s data transfer rate, and support for Virtualization Technology and Integrated Management Engine. It also incorporates ACPI features for power management and reliability, including a Slow Blinking LED for Suspend-State Indicator and Main Switch Override Mechanism.
In terms of power supply, it can accommodate 24-pin ATX power supplies and requires two 12V 8-pin power connections for adequate power supply. Using a high-quality power supply that meets ATX power supply Specification 2.02 or above is recommended, along with installing a line filter and power surge protector for noise and surge protection.
The Super I/O chip on the motherboard provides various functions, including floppy disk drive control, serial communication ports (UARTs), and ACPI support for legacy and ACPI power management. With its robust features and capabilities, the X8DAH+ motherboard is designed to meet the demands of high-performance computing environments.
