Description
Technical Field
The present invention relates to a server system, and more particularly, to a server system with a bandwidth switching function.
Background
Generally, the existing servers are usually designed to be scalable and upgradable in hardware, so as to meet the needs of different clients. The extensible upgrade of hardware is mostly the expansion of storage devices, and because the existing servers are mostly developed and designed based on the X86 platforms of AMD and Intel, a certain number of slots or ports and other plug-in components are usually reserved on the motherboard when designing the architecture of the server, so as to adjust the performance of the server through different hardware configurations, thereby meeting the requirements of customers.
However, no matter the AMD or Intel platform, the plug-in components that can be installed therein are limited, and further expansion and upgrade of hardware are limited, so that most of the existing server systems have some problems in expansion and upgrade, such as insufficient development and application of processors, too single configuration of hardware, failure to meet the requirements of some clients, too long development cycle, and too high development cost of the server system.
Please refer to the first and second figures, wherein the first figure is a system block diagram of a conventional server system in the prior art; the second diagram is a schematic plan view showing a prior art server system. As shown in the first and second figures, a conventional server system PA100 includes a processor PA1, a plurality of default connectors PA2 (only one is shown in the first figure, only one is shown in the second figure), an expansion connector PA3, and an expansion connector PA 4.
The processor PA1 is a Central Processing Unit (CPU). The default connector PA2 is electrically connected to the processor PA1 for inserting and installing an electronic device PA 200. The expansion connectors PA3 and PA4 are respectively electrically connected to the processor PA 1; the expansion connector PA3 is used for plugging and mounting an expansion electronic device PA300, and the expansion connector PA4 is used for plugging and mounting an expansion electronic device PA 400.
As mentioned above, the default connector PA2 is, for example, a PCIe slot of X8 specification, and the electronic device PA200 is, for example, an NVMe backplane of X8 specification, for mounting an NVMe hard disk. The expansion connector PA3 is, for example, a PCIe slot of X8 standard, the expansion electronic device PA300 is, for example, an expansion card of X8 standard, and the expansion card of X8 standard includes an external electronic device such as a hard disk backplane or a network card. The expansion connector PA4 is, for example, a PCIe slot of X16 standard, the electronic device PA400 is, for example, an expansion card of X16 standard, and the expansion card of X16 standard includes an external electronic device such as a hard disk backplane or a network card.
As described above, based on the X86 platform of AMD or Intel, the number of pins of the processor PA1 is fixed, and the available bandwidth is limited, so that the server system PA100 can meet most of the customer requirements, usually the expansion connectors PA4 and PA3 of the X16 specification and the expansion connectors PA 8 specification are reserved for expansion and upgrade, and then the remaining bandwidth is divided into a plurality of preset connectors PA2, so that in actual use, the expansion connectors PA3 and PA4 of the X8 specification and the X16 specification can be provided for users to plug in the expansion electronic devices PA300 and PA400 of the X16 specification, thereby meeting the requirements of most of users.
However, if the expansion electronic device PA400 that the user wants to install is of the X8 specification, although the expansion connector PA4 is downward compatible, the bandwidth of the expansion connector PA4 cannot be fully used; on the contrary, if the expansion connector PA4 is originally designed to be of the X8 specification, although the bandwidth of X8 can be released to set another default connector PA2, it cannot be supported when the user wants to install the expansion electronic device PA400 of the X16 specification. Therefore, in the prior art, no matter how the server system PA100 is designed, it cannot satisfy users with different requirements at the same time, and thus, it is necessary to design multiple types of numbers to meet the different requirements of the users, which results in an increase in manufacturing cost.
Disclosure of Invention
In view of the prior art, because the existing server system is mainly developed and designed based on the X86 platform of AMD and Intel, the expansion and upgrade functions of the server are limited, the flexible configuration space of the server system is relatively reduced, and the supported customer requirements are also reduced, and in order to meet other customer requirements, additional development and design are required, which increases the development cost of the whole server system; therefore, a primary objective of the present invention is to provide a server system with a bandwidth switching function, which can increase the flexible configuration space of the server system, and further support more kinds of client requirement configurations.
The present invention provides a server system with bandwidth switching function, which comprises a processor, a flexible expansion connector and a circuit switching connector.
The flexible expansion connector is electrically connected to the processor by an M channel and has a bandwidth expansion port. The circuit switching connector is electrically connected with the processor through the N channels.
When the circuit switching connector is electrically connected with a default connector through a first N-channel transmission cable, the elastic expansion connector is used for connecting a first expansion electronic device in a connecting mode and electrically connecting the first expansion electronic device with the processor through an M channel; when the circuit switching connector is electrically connected to the bandwidth expansion port through a second N-channel transmission cable, the flexible expansion connector is used for connecting a second expansion electronic device, and electrically connecting the second expansion electronic device to the processor through an L channel, wherein L is M + N.
In a subsidiary technical means derived from the above-mentioned essential technical means, wherein M is N.
In a subsidiary technical means derived from the above-mentioned essential technical means, wherein L is 16 or 32.
In an auxiliary technical means derived from the above-mentioned necessary technical means, the server system with bandwidth switching function further comprises a basic expansion connector, wherein the basic expansion connector is electrically connected to the processor through N channels and is used for connecting an expansion electronic device.
In an auxiliary technical means derived from the above-mentioned necessary technical means, the flexible expansion connector is an ocp (open computer project)3.0 slot.
In an auxiliary technical means derived from the above-mentioned necessary technical means, the server system with bandwidth switching function further comprises a default connector, and the default connector is electrically connected to the processor through N channels and is used for connecting a first electronic device.
As described above, the present invention mainly utilizes the design of the circuit switch to allow the user to connect the circuit switching connector and the bandwidth expansion port through the second N-channel transmission cable, so that the bandwidth of the flexible expansion connector is upgraded from M channel to L channel for the installation of the second expansion electronic device with L channel specification; or, when the second expansion electronic device is an M channel, the first N channel transmission cable is connected to the circuit switching connector and the default expansion connector, so that the preset expansion connector can be used for installing the N channel second electronic device.

Referring to the third to fourth drawings, the third drawing is a system block diagram showing a circuit switching connector electrically connected to a default expansion connector by a first N-channel transmission cable in a server system with a bandwidth switching function according to a preferred embodiment of the present invention; the fourth diagram shows a system block diagram of the circuit switching connector electrically connected to the bandwidth expansion port via the second N-channel transmission cable in the server system with bandwidth switching function according to the preferred embodiment of the present invention.
As shown in the third and fourth figures, a server system 100 with bandwidth switching function includes a processor 1, a plurality of default connectors 2 (only one is labeled), a basic expansion connector 3, an elastic expansion connector 4, a circuit switching connector 5, and a default expansion connector 6.
The processor 1 is a Central Processing Unit (CPU). The default connector 2 is electrically connected to the processor 1 by N channels and is used for connecting a first electronic device 200. Wherein N is 8 in the present embodiment, that is, the predetermined connector 2 is, for example, a PCIe slot with a channel number of X8 specification, and the first electronic device 200 is, for example, a hard disk backplane with a port of X8 specification.
The basic expansion connector 3 is electrically connected to the processor 1 by N channels and is used for connecting an expansion electronic device 300. The basic expansion connector 3 is, for example, a PCIe slot with a channel number of X8 specification, and the expansion electronic device 300 is, for example, a hard disk backplane with a port of X8 specification.
The flexible expansion connector 4 is electrically connected to the processor 1 by an M channel, and the flexible expansion connector 4 has a bandwidth expansion port 41. Wherein M is 8 in the embodiment, and the bandwidth expansion port 41 is an N-channel port, so the flexible expansion connector 4 can be used for a first expansion electronic device 400a with the number of plugging channels of X8 (i.e. 8 channels) or a second expansion electronic device 400b with the number of plugging channels of X16. In addition, in practical applications, the flexible expansion connector 4 is, for example, an ocp (open computer project)3.0 slot.
The circuit switching connector 5 is electrically connected to the processor 1 by N channels. However, when the circuit switching connector 5 is electrically connected to the predetermined expansion connector 6 through a first N-channel transmission cable C1 as shown in the third diagram, the flexible expansion connector 4 is used to connect the first expansion electronic device 400a and electrically connect the first expansion electronic device 400a to the processor 1 through the M channel; when the circuit switching connector 5 is electrically connected to the bandwidth expansion port 41 through a second N-channel transmission cable C2, the flexible expansion connector 4 is used to connect the second expansion electronic device 400b, and electrically connect the second expansion electronic device 400b to the processor 1 through an L channel, where L is M + N, in this embodiment, since N and M are both 8, L is 16, but in other embodiments, this is not limiting, and when N and M are both 16, L is 32.
With reference to the fifth and sixth figures, the fifth figure is a schematic plan view showing that in the server system with bandwidth switching function according to the preferred embodiment of the present invention, the circuit switching connector is electrically connected to the predetermined expansion connector by the first N-channel transmission cable; the sixth view is a schematic plan view showing that in the server system with bandwidth switching function provided in the preferred embodiment of the present invention, the circuit switching connector is electrically connected to the bandwidth expansion port by the second N-channel transmission cable.
As shown in the third and fifth figures, in practical use, if a user wants to install the first electronic expansion device 400a with the M-channel specification in the server system 100 with the bandwidth switching function of this embodiment, since the flexible expansion connector 4 is electrically connected to the processor 1 by the M-channel by default, and M is 8, when the first electronic expansion device 400a is plugged into the flexible expansion connector 4, the first electronic expansion device 400a with the channel number of X8 specification can be electrically connected to the processor 1 by 8 bandwidths. In addition, the first N-channel transmission cable C1 is plugged into the circuit switching connector 5 and the predetermined expansion connector 6, so that the predetermined expansion connector 6 can be electrically connected to the processor 1 by N-channels, and thus the predetermined expansion connector 6 can be used to plug a second electronic device (not shown) having N-channels.
On the other hand, as shown in the fourth to sixth figures, in practical use, if a user wants to install the second electronic expansion device 400b with the L-channel specification in the server system 100 with the bandwidth switching function of this embodiment, although the flexible expansion connector 4 is electrically connected to the processor 1 by the M-channel by default, the second N-channel transmission cable C2 is plugged into the circuit switching connector 5 and the bandwidth expansion port 41, so that the transmission bandwidth between the flexible expansion connector 4 and the processor 1 can be upgraded to the L-channel by the original M-channel plus the N-channel provided by the circuit switching connector 5, and therefore the second electronic expansion device 400b with the L-channel specification can be electrically connected to the processor 1 by the L-channel.
In summary, in the server system with bandwidth switching function of the present invention, the elastic expansion connector is electrically connected to the processor by default through the M channel, and the bandwidth expansion port of the N channel is reserved, and the server system is provided with the circuit switching connector electrically connected to the processor by the M channel, so that a user can select the first N channel transmission cable to connect the circuit switching connector and the default expansion connector when the second expansion electronic device with the M channel specification is to be installed, so that the preset expansion connector can be used for plugging the second electronic device with the N channel specification; on the other hand, when the user wants to install the second expansion electronic device with the specification of the L channel, the user can select the second N-channel transmission cable to connect the circuit switching connector and the bandwidth expansion port, so that the bandwidth between the flexible expansion connector and the processing is upgraded to the L channel from the accumulation of the M channel and the N channel, and the second expansion electronic device with the specification of the L channel is further installed.
As described above, the present invention mainly utilizes the design of the circuit switch to allow the user to connect the circuit switching connector and the bandwidth expansion port through the second N-channel transmission cable, so that the bandwidth of the flexible expansion connector is upgraded from M channel to L channel for the installation of the second expansion electronic device with L channel specification; or, when the second expansion electronic device is an M channel, the first N channel transmission cable is connected to the circuit switching connector and the default expansion connector, so that the preset expansion connector can be used for installing the N channel second electronic device. Compared with the prior art in which the expansion connectors of the server system are all designed with a fixed bandwidth, the invention can increase the flexible configuration space of the server system by flexibly switching the bandwidth of the flexible expansion connector, thereby supporting more kinds of configuration required by the client.
The above detailed description of the preferred embodiments is intended to more clearly illustrate the features and spirit of the present invention, and is not intended to limit the scope of the present invention by the preferred embodiments disclosed above. On the contrary, it is intended to cover various modifications and equivalent arrangements included within the scope of the claims.
