Problems solved by technology

However, compared to the Romley platform, existing blade server motherboards have certain disadvantages in terms of the number of CPU cores, QPI, number of memory channels, and PCIExpress interface. The motherboard is integrated with a SAS controller (Serial Advanced SCSI). Unnecessary consumption of cost

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] figure 1 It is a schematic block diagram of a partial structure of a blade server motherboard based on a Romley platform according to an embodiment of the present invention.

[0032] Such as figure 1 As shown, the mainboard of the blade server is a two-way platform, and the mainboard of the blade server includes two CPUs, specifically a first CPU10 and a second CPU12. The first CPU 10 and the second CPU 12 are interconnected through two QPI buses. Each CPU supports four-channel DDR memory, such as four-channel DDR3 memory, and each channel can be connected to two memory 20 or 22. DDR specifically refers to double data rate synchronous dynamic random access memory (Double Data Rate Synchronous Dynamic Random Access Memory sdram). In the embodiment of the present invention, the first CPU 10 and the second CPU 12 can support U / R DDR3 memory or LV DDR ...

Abstract

The invention discloses a blade server motherboard, which comprises two CPUs (central processing units), a Southbridge chip and a host channel adapter HCA card. The two CPUs are connected through two rapid channel interconnection buses; each CPU can support a four-channel DDR (double data rate) memory, and two DDR memories are inserted into each channel; the Southbridge chip is respectively connected with the CPUs through a PCIE (peripheral component interface express) bus and a DMI (direct memory interface) bus; and the host channel adapter HCA card is connected with the CPUs through PCIE buses. The invention also correspondingly provides a blade server system. By adopting the blade server motherboard and the blade server system, high-performance computation can be supported, and the capacity of expansion can also be well supported.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a blade server motherboard and a blade server system. Background technique [0002] The Romley platform is Intel's new-generation x86 architecture CPU. The Romley blade server mainboard supports dual-channel CPUs. For example, the CPU code-named Sandy Bridge launched by Intel. Romley platform processors will utilize all Sandy Bridge cores, with two Quick Path Interconnects (QPI) between sockets to improve performance for symmetric multiprocessing workloads, and four memory channels per socket , each channel has three dual-in-line memory modules to obtain higher memory capacity and bandwidth, and each slot has 40 PCI Express 3.0 for peripheral expansion. PCI Express (hereinafter referred to as PCIE) is a next-generation I / O interface standard proposed by Intel. [0003] Most existing blade server motherboards are based on Intel's previous generation x86 architecture Westmere pla...
