Problems solved by technology

[0005] The embodiment of the present invention provides a system device and configuration method based on PCIe SWITCH, which is used to solve the requirement of compatible single-channel and dual-channel shipments by selecting the number of CPUs in the server based on x86 architecture in the prior art, because each CPU corresponds to Part of the performance of the whole machine, so there is a technical problem that when only one CPU is installed, the performance of the whole machine is cut off, resulting in a single-socket server that cannot support all functions of the whole machine, and is only applicable to CPU manufacturers that support socket mounts.

Embodiment 1

[0027]The embodiment of the present invention provides a system device based on PCIe Switch, such asfigure 1 As shown, the apparatus comprises:

[0028]First central processor 1;

[0029]PCIe Switch3, the PCIe Switch 3 is connected to the first central processor 1;

[0030]The control chip 4 is connected to the first central processor 1, wherein the first central processor 1 transmits the first central processor 1 in a bit signal to the control chip 4;

[0031]The first firmware chip 5, the first firmware chip 5 is connected to the PCIe Switch3 by the control chip 4;

[0032]The first peripheral interface 7, the first outer interface 7 is connected to the PCIe Switch3;

[0033]The second peripheral interface 8 is connected to the PCIe Switch3.

[0034]Specifically, the English name of the central processor is Central Processing Unit, a referred to as a CPU, the central processor as a computing and control core of a computer system, and is the final execution unit of information processing and program ru...

Embodiment 2

[0042]Embodiments of the present invention also provide a system configuration method based on PCIe Switch, such asfigure 2 As shown, the method includes:

[0043]Step 110: Get the work mode of the server, where the working mode includes a single server and a dual server;

[0044]Step 120: Determine if the working mode of the server is the single circuitry;

[0045]Step 130: If the operation mode of the server is the single server, the first central processor 1 transmits the first central processor 1 in the bit signal to the control chip 4;

[0046]Step 140: The control chip 4 switches the firmware interface of the PCIe Switch3 to the first firmware chip 5;

[0047]Step 150: The first central processor 1 provides the first outer interface 7 and the second peripheral interface 8 through the PCIe Switch 3.

[0048]Further, it is further determined whether the working mode of the server is the single server, and further includes: if the working mode of the server is the single server, simply install th...

Abstract

The invention provides a PCIe SWITCH-based system device and a PCIe SWITCH-based configuration method. The PCIe SWITCH-based system device comprises: a first central processing unit; a PCIe SWITCH which is connected with the first central processing unit; a control chip which is connected with the first central processing unit; a first firmware chip, wherein the first firmware chip is connected with the PCIe SWITCH through the control chip; a first peripheral interface, wherein the first peripheral interface is connected with the PCIe SWITCH; and a second peripheral interface, wherein the second peripheral interface is connected with the PCIe SWITCH. The PCIe SWITCH is added between the CPU and the peripheral equipment, so that the compatibility of a single-path server and a double-path server is realized, the single-path shipment of the CPU is supported, the consistency of the functions of the whole single-path server and the whole functions of the whole multi-path server is kept, the delivery and maintenance work of the same series of whole machines is greatly simplified, and the technical effect of higher system expansibility is achieved.

Description

Technical field[0001]The present invention relates to the field of single-double server configuration, and more particularly to a system device and a configuration method based on PCIe Switch.Background technique[0002]The current X86 architecture-based server, mainstream CPU vendor is Intel and AMD vendors, usually using the Socket mounting seat to connect between CPU and motherboard, with two CPU sockets on the motherboard. When there is a dual shipment demand, both CPUs need to be installed; when there is a single shipping demand, just install a CPU, such a motherboard can be compatible with the shipping needs of the dual and single servers.[0003]However, in the process of implementing the technical solution in the present application embodiment, the inventor of the present application discovered at least the following technical problems:[0004]The X86 architecture server based on the X86 architectural server is compatible with the number of monocular and dual shipments by optional...
