Thereby, the convenience of usage is substantially improved.
As shown in FIG. 1, since the central power supply module 14 and the integrated network controller module 16 of this embodiment are disposed inside a same casing, the connector modules 130 of the servers 100 are configured for being electrically connected to the central power supply module 14 and the integrated network controller module 16 simultaneously by connecting to the casing directly. Thereby, the server rack system 10 is configured for providing both power and network information for the servers 100.
Although only two layers of the rack 12 of the server rack system 10 are illustrated in FIG. 1, a number of the layers of the rack 12 should not be construed as a limitation to the disclosure. Each of the layers of the rack 12 can accommodate the server 100 as shown in FIG. 1. In other words, all the servers 100 in the rack 12 may be respectively electrically connected to the central power supply module 14 and the integrated network controller module 16 of the server rack system 10 through the connector modules 130 in order that the server rack system 10 is configured for providing both power and network communication for the servers 100.
When the servers 100 are disposed in the rack 12 of the server rack system 10, the power distribution circuit 132 is electrically connected to the central power supply module 14, and the network distribution unit 134 is connected to the integrated network controller module 16 of the rack 12. Therefore, the server rack system 10 is configured for providing both power and network communication for the servers 100. Also, the dispositions of power and network communication devices are not required inside the cases 110 of the servers 100. Thereby, more space inside the cases 110 of the servers 100 may be available and provided for the motherboard modules 120 or other elements in order to enhance the computational density and performance of the servers 100.
Furthermore, as shown in FIG. 1, each of the servers 100 further comprises a plurality of expansion units 150 electrically connected to the motherboard modules 120 respectively.

Thereby, the connector modules 130 of the servers 100 is connected to the central power supply module 14 and the integrated network controller module 16 of the server rack system 10 directly. Furthermore, since the output interfaces 152 or the input interfaces 154 of the expansion units 150 are exposed on the second lateral side 116 of the cases 110, the second lateral side 116 is disposed at an outer side of the rack 12 when the servers 100 are disposed in the rack 12. Thereby, it is more convenient for the user to insert external devices into the output interfaces 152 or the input interfaces 154 disposed on the second lateral side 116.
Also, in this embodiment, each of the servers 100 further comprises a plurality of storage units 160.

As shown in FIG. 2, some of the storage units 160 are disposed between the first lateral side 114 of the case 110 and the motherboard modules 120. In other words, the storage units 160 are disposed above the interconnecting plates 140. Since a thickness of the interconnecting plates 140 is relatively thin and an excessive space is available above the interconnecting plates 140, the storage capacity of the servers 100 is configured for being enhanced through the disposition of the storage units 160 in the excessive space. As shown in FIG. 2, the storage units 160 disposed above the interconnecting plates 140 are 3.5 inch hard disks and four of the storage units 160 are disposed above the two interconnecting plates 140. Nevertheless, a quantity and type of the storage units 160 should not be construed as limitations to the disclosure.
In FIG. 2, the motherboard modules 120 of the servers 100 are covered by the casing. Please refer to FIG. 3 and FIG. 4 in order to understand the disposition of the motherboard modules 120. FIG. 3 is a perspective view of one of the motherboard modules of the server in FIG. 1. FIG. 4 is a perspective view of another one of the motherboard modules of the server in FIG. 1. Each of the motherboard modules 120 comprises at least one heat source 126 and at least one heat dissipation module 128.
In this embodiment, each of the motherboard modules 120 has two of the heat sources 126, and the heat sources 126 are central processing units. Nonetheless, a type of the heat sources 126 should not be construed as a limitation to the disclosure. The heat dissipation modules 128 of this embodiment comprise heat dissipation fins disposed near the heat sources 126 for eliminating the heat produced by the heat sources 126 by thermal contact. The heat sources 126 in FIG. 3 are disposed on the motherboard module 120 in an interlacing arrangement. The two heat dissipation modules 128 are disposed by a side of the two heat sources 126 respectively. The heat sources 126 in FIG. 4 are disposed side by side to each other on the motherboard module 120. The four heat dissipation modules 128 are disposed by two sides of the two heat sources 126 respectively. FIG. 3 and FIG. 4 are merely used for showing the two ways of how the heat sources 126 and the heat dissipation modules 128 are disposed on the motherboard module 120. The way of disposition of the heat sources 126 and the heat dissipation modules 128 on the motherboard module 120 should not be construed as a limitation to the disclosure.
In FIG. 3, the storage units 160 are 3.5 inch hard disks. In FIG. 4, the storage units 160 are 2.5 inch hard disks or solid state drives. But the type and quantity of the storage units 160 should not be construed as limitations to the disclosure. A passage is disposed between the two storage units 160 in FIG. 4 for the heat produced by the heat sources 126 to depart through the passage. Nevertheless, the disposition of the storage units 160 on the motherboard module 120 should not be construed as a limitation to the disclosure.
Additionally, in this embodiment, some of the storage units 160 are disposed by one side of the heat sources 126 and the heat dissipation modules 128 on the motherboard module 120, and the expansion units 150 are disposed by another side of the heat sources 126 and the heat dissipation modules 128 on the motherboard module 120. In other embodiments, however, the storage units 160 may also be disposed by the two sides of the heat sources 126 and the heat dissipation modules 128 on the motherboard module 120. In other words, the expansion units 150 is configured for being replaced by the storage units 160 based on requirements in order to enhance the storage density of the server 100. Nonetheless, the disposing relationship between the storage units 160, the expansion units 150 and the motherboard module 120 should not be construed as a limitation to the disclosure.
As a conclusion, the server rack system of the disclosure obtains the power from exterior power source through the central power supply module and distributes the power to the servers disposed in the rack, and manages the network data of exchange information of the motherboard modules of the servers disposed in the rack through the integrated network controller module. Furthermore, the motherboard modules of the servers of the disclosure are connected to the central power supply module and the integrated network controller module of the server rack system through the connector modules.
