Description

computer system

technical field

The invention relates to the field of computers, in particular to a computer system.

Background technique

Existing computers or servers will have peripheral expansion interfaces PCI, PCI-X or PCI-E, and users can add peripheral component expansion cards according to their needs, such as display cards, network cards, sound cards, TV cards, etc. Among them, PCI is the abbreviation of Peripheral Component Interconnect (peripheral component interconnection standard). It is the most widely used interface in personal computers at present. Almost all motherboard products have this kind of slot. There are the largest number of slot types; PCI-X is an updated version of the PCI specification; PCI-E is the abbreviation of PCI Express, which is a new generation of bus interface technology. PCIExpress interfaces vary according to the bus width, including X1, X4, X8, and X16. Shorter PCI Express cards can be inserted into longer PCI Express slots. The PCI Express interface can support hot plugging.

There are currently two types of expansion cards on the market, one is a low profile card and the other is a full height card. The interface and bezel height of half-height cards and full-height cards are the same, but the "card body" height of half-height cards is usually shorter than that of full-height cards. At present, the application of full-height cards is relatively common in the market.

Common computers and servers are limited by the size of the chassis, such as 2U servers, there is not enough space at the top of the PCI slot, and when installing a full-height card, you will find that it cannot be installed. Therefore, only half-height PCI/PCI-X/PCI-E expansion cards can be supported. The system structure as shown in Figure 1, it comprises the cabinet 2 that has rear window 1, is provided with main board 3 in cabinet 2, is inserted with half-height card 4 on the main board 3, in this system, due to being affected by the height of the cabinet Restrictions, only half-height cards can be installed, not full-height cards.

In this way, for existing common computers and servers, when users need to add expansion cards, they can only choose half-height cards instead of full-height cards. sexual choice.

Detailed ways

The embodiment of the present invention aims to provide a solution that enables a system structure that only supports half-height cards to also support full-height cards, thereby improving the interchangeability and flexibility of users in selecting expansion cards. Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

The computer system of the embodiment of the present invention, as shown in FIG. 2 , includes a case 20 with a rear window 10 , and a motherboard 30 is arranged inside the case 20 .

Among them, five PCI and/or PCI-E slot interfaces 40 are arranged on the main board 30. Due to the limitation of the internal space of the chassis, only half-height expansion cards, such as sound cards, can be plugged into these five slot interfaces. , network card, TV card, etc. In addition to the five slot interfaces 40, a slot interface 50 is extended on the motherboard 30, wherein the slot interface 50 is a PCI slot interface or a PCI-E slot interface. The expanded slot interface 50 cooperates with one of the five slot interfaces to form a group of first slot interfaces consisting of two slot interfaces of different specifications and capable of transmitting PCI and PCI-E signals. Slot interface group 60 . In the embodiment of the present invention, the expanded slot interface 50 is a PCI-E slot interface, which cooperates with one of the five slot interfaces to form the first PCI and PCI-E signal transferable slot interface. Slot interface set 60. The openings of the two slot interfaces in the first slot interface group 60 face upward and are arranged at intervals, and the two slot interfaces are in the same plane perpendicular to the board surface of the main board 30 .
