Description
Technical Field
The invention relates to a server system and a switching method thereof.
Background
With the progress of communication technology, the network and the application devices thereof are increasingly used, and the convenience in life is further improved by virtue of the remote data transmission and processing efficiency provided by the network and the application devices.
However, servers are an important component of network architecture. In order to ensure the stability of the server operation, two network ports that are redundant to each other are generally provided for network connection, and usually the two network ports are connected to the same network controller, and the network controller is connected to the south bridge chip of the server, so as to implement the network function of the server.
Referring to fig. 1, a server system is shown. As shown in fig. 1, the server system 100 includes a main board 110. The main board 110 includes a Central Processing Unit (CPU)115, a north bridge 120, a south bridge 130, a bios 140, a Baseboard Management Controller (BMC) 150, a first network controller 160, and a second network controller 174.
The first network controller 160 is electrically connected to the south bridge chip 130, and is connected to a first network port 180 and a second network port 190, and the central processing unit 115 is connected to the network through the first network controller 160 and any one of the first network port 180 and the second network port 190. Since the bandwidth of the data transmission interface for connecting the south bridge chip 130 and the first network controller 160 is only about 476.8MB/S, the network speed of the first network port 180 and the second network port 190 is limited, and thus a better and suitable data transmission speed cannot be provided.
On the other hand, currently, a general server has a baseboard management controller for monitoring and managing the operating status of the server. Referring to fig. 1, the bmc 150 is electrically connected to the south bridge chip 130 and the bios 140. The baseboard management controller 150 is independent of the computing system composed of the central processing unit 115, the north bridge chip 120 and the south bridge chip 130; more specifically, it is a monitoring management system for monitoring and managing the operating state of the server system 100. No matter whether the computing system with the central processing unit 115 as a core is in a power-on state or a power-off state, the baseboard management controller 150 is in a working state, and one basic function of the baseboard management controller 150 is to perform remote monitoring and management through a network. Thus, as shown in FIG. 1, baseboard management controller 150 is coupled to a separate second network controller 174 and management port 172 dedicated to monitoring and managing server system 100 remotely over a network. Thus, the management port, whether functional or connected in a server system, is distinct from the first network port 180 and the second network port 190.
However, it is relatively expensive to provide two network controllers and more than two network ports in one server. And different users have different requirements on configuration and cost. Therefore, how to provide flexible configuration options for a server system to meet different market demands without affecting the basic functions of the server system has become an urgent problem to be solved.

Detailed Description
In order to make the description of the present invention more complete and complete, reference is made to the various embodiments described below and the accompanying drawings, in which like numerals represent the same or similar elements.
Referring to fig. 2, a server system according to an embodiment of the invention is shown. As shown in fig. 2, the server system 100 at least includes a main board 110. The main board 110 includes a Central Processing Unit (CPU)115, a north bridge 120, a south bridge 130, a bios 140, a BMC (baseboard management controller)150, and a first network controller 160. The server system 100 further includes an intelligent platform management interface (IPMI Card)170 plugged into the motherboard 110 and electrically connected to the bmc 150. The north bridge 120 is electrically connected to the central processing unit 115, the south bridge 130 is electrically connected to the north bridge 120, and the bios 140 is electrically connected to the south bridge 130, thereby forming an operating system with the central processing unit 115 as a core. The first network controller 160 is electrically connected to the north bridge 120 through a data transmission interface, and is connected to a first network port 180 and a second network port 190, and the central processor 115 is connected to the network through the first network controller 160 and any one of the first network port 180 and the second network port 190. The baseboard management controller 150 is electrically connected to the south bridge chip 130 and the BIOS 140. The bmc 150 is a system independent from the cpu 115, and is configured to monitor and manage the operating state of the server system 100, including the operating temperature and the operating voltage of each part of the server system 100, and control and adjust the operation of the fan according to each operating temperature, that is, the bmc 150 generates a management data, which covers data related to the system state, such as temperature, voltage, and fan speed. And the bmc 150 is always in an active state regardless of whether the server system 100 is in an on state or an off state. The bmc 150 is also electrically connected to the first network controller 160.
Furthermore, the first network controller 160 is electrically connected to the north bridge 120, so as to implement the functional characteristics of having two network ports. In one embodiment of the present invention, the first network controller 160 is a network controller
82576 Gigabit ethernet controller and using PCI-E x4 bus interface as data transmission interface to receive network data from north bridge chip 120 for transmission to first network port 180 and second network port 190. Since the bandwidth of PCI-E x4 is about 15258.9Mbps, the transmission speed of network data can be greatly increased.
Referring to fig. 2, the ipmi external card 170 is inserted into the motherboard 100 and electrically connected to the bmc 150, and includes a second network controller 174 and a management port 172, wherein the management port 172 is connected to the second network controller 174. Wherein, the bios 140 detects whether the ipmi card 170 is plugged into the motherboard 110, and when the ipmi card 170 is not plugged into the motherboard 110 and is not electrically connected to the bmc 150, the bios 140 notifies the bmc 150 to transmit management data to the second network port 190 through the first network controller 160 to communicate with a remote control; when the external smart card 170 is inserted into the motherboard 110 and electrically connected to the bmc 150, the bios 140 notifies the bmc 150 to communicate with the remote controller through the management port 172 of the external smart card 170. At this time, the first network port 180 and the second network port 190 are all used as network communication ports of the central processing unit 115, and are redundant to each other, when a problem occurs at the first network port 180, the central processing unit 115 is connected to the network through the second network port 190, and vice versa.
More specifically, the SMI add-in card 170 has a second network controller 174 for transmitting the management data generated by the BMC 150 to the management port 172. In addition, the smart management interface card 170 further has a presence signal pin 176 electrically connected to the south bridge chip 130, and the south bridge chip 130 reads the state of the presence signal pin 176 and stores a state value in a register of the south bridge chip 130. Then, the bios 140 reads a register in the south bridge chip 130 to determine whether the ipmi card 170 is inserted into the motherboard 110 and electrically connected to the bmc 150.
In addition, when the bios 140 detects that the ipmi card 170 is plugged into the motherboard 110, a first control signal is transmitted to the bmc 150, so that the bmc 150 transmits management data via a Reduced Media Independent Interface (RMII) according to the first control signal, and the management data is then analyzed by the second network controller 174 and transmitted to the management port 172 of the ipmi card 170.
However, when the bios 140 does not detect that the ipmi card 170 is plugged into the motherboard 110, a second control signal is transmitted to the bmc 150, so that the bmc 150 transmits management data through a Network Controller side band interface (NC-SI) according to the second control signal, and the management data is then parsed by the first Network Controller 160 and transmitted to the second Network port 190. At this time, the first network port 180 is still used as a network communication port of the cpu 115 system, so as to ensure that the cpu 115 is connected to the network through the first network port 180.
Referring to fig. 3, a flow chart of a switching method of a server system according to an embodiment of the invention is shown. The switching method of the server system in this embodiment is, for example, applied to the server system 100 according to an embodiment of the present invention. As shown in FIG. 3, the switching method of the server system includes the following steps (S1-S4 b).
First, in step S1, the bios 140 is provided to detect whether the ipmi card 170 is inserted into the motherboard 110, and is electrically connected to the bmc 150.
More specifically, in an embodiment of the present invention, when the external smart platform management interface card 170 is inserted into the motherboard 110 and electrically connected to the bmc 150, a presence signal is provided from a presence signal pin 176 of the external smart platform management interface card 170 to a south bridge chip 130, and a status value of the presence signal is stored in a register of the south bridge chip 130. Then, the BIOS 140 reads a register of the south bridge chip 130 to detect whether the IPMI card 170 is properly inserted on the motherboard 110.
In step S2a, when the bios 140 detects that the ipmi card 170 is plugged into the motherboard 110 and further electrically connected to the bmc 150, the bios 140 provides a first control signal to the bmc 150; however, in step S2b, when the bios 140 detects that the ipmi card 170 is not plugged on the motherboard 110, the bios 140 provides a second control signal to the bmc 150.
In step S3, the bmc 150 determines whether the first control signal or the second control signal is received, and switches the generated management data.
In step S4a, when the bmc 150 receives the first control signal, the bmc 150 switches and uses a management port 172 of the ipmi card 170 to communicate with a remote control according to the received first control signal. Moreover, the north bridge 120 switches and transmits a network data using the first network port 180 and the second network port 190 through the first network controller 160.
In addition, in step S4b, when the bmc 150 receives the second control signal, the bmc 150 switches and communicates with the remote controller using the second network port 190 according to the received second control signal. On the other hand, the north bridge 120 switches and transmits a network data using the first network port 180.
Therefore, the server system and the switching method thereof according to the embodiments of the present invention can properly and flexibly meet different requirements of users on network ports, and can also increase the transmission speed of network data thereof in a customized manner, thereby increasing market competitiveness and popularity.
Hereinbefore, specific embodiments of the present invention are described with reference to the drawings. However, those skilled in the art will appreciate that various modifications and substitutions can be made to the specific embodiments of the present invention without departing from the spirit and scope of the invention. Such modifications and substitutions are intended to be included within the scope of the present invention as defined by the appended claims.
