Shenwei 1621 CPU ICH2-free nest plate server mainboard

Abstract

The invention discloses a Shenwei 1621 CPU ICH2-free nest plate server mainboard. The mainboard comprises a CPU, a BIOS chip, a memory slot, a mainboard time sequence control chip, a PCIE bus extension chip, a BMC management chip, a network chip, an SATA chip, an SAS chip, a USB chip and a PCIE slot. The BIOS chip, the memory slot, the BMC management chip and the PCIE bus expansion chip are directly connected with the CPU. The CPU supports two groups of PCI-EX8 signals; one group of PCI-EX8 signals is used as the input of the SAS extension chip, and two groups of Mini-SASX4 interfaces are provided for the outside; The other group of PCI-E X8 signals are connected with the input end of the PCI-E bus expansion chip; the PCIE bus expansion chip provides one path of PCIE3.0 X16, three paths ofPCI-E3.0 X8, two paths of PCI-EX4 and four paths of PCI-EX1 as output, and the PCIE bus expansion chip is used for expanding various low-speed data ports, high-speed data ports and low-speed data ports. The domestic Shenwei SW1621 CPU is adopted to carry the domestic deep operation system, and the Shenwei 1621 CPU ICH2-free nest plate server mainboard has the advantages of being high in processing speed, flexible in interface expansion, high in cost performance, high in safety level and the like.

Description

technical field [0001] The invention relates to the technical field of server motherboards, and more specifically relates to a Shenwei 1621CPU server motherboard without ICH2 chips. Background technique [0002] After the Huawei and ZTE incidents, the localization of the information industry has gradually been put on the agenda. As the top priority of the information industry, the independent and controllable server industry is very important. In recent years, the country has increased investment in the domestic independent and controllable information industry, and major server manufacturers have also launched a batch of domestic independent and controllable servers with Shenwei SW1621 CPU as the core, but most of these server manufacturers use ICH2 chips. The design scheme is not only expensive, but also subject to great constraints in performance. [0003] Therefore, how to provide a Shenwei 1621CPU server motherboard without ICH2 chip set with low price and excellent pe...
