Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.

It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.

While the present invention may be embodied in various forms, there is shown in the drawings and will hereinafter be described some exemplary and non-limiting embodiments, with the understanding that the present disclosure is to be considered an exemplification of the invention and is not intended to limit the invention to the specific embodiments illustrated.

In view of the above object, a first aspect of the embodiments of the present invention proposes an embodiment of a blade hardened server system based on a VPX architecture, where the blade hardened server system based on the VPX architecture includes:

a plurality of computer units;

Fig. 1 is a schematic structural diagram of an embodiment of a blade reinforcement server system based on a VPX architecture provided by the present invention. In the embodiment shown in fig. 1, the multi-unit server as a technical verification platform includes 2 power supply units, 2 switching units, 8 computer units and 3 plug-in units. Wherein, 2 switching units are used as system core main control units and respectively used as main and slave nodes (namely a main control switching unit and a slave control switching unit).

Fig. 2 is a schematic connection diagram of an embodiment of a blade reinforcement server system based on a VPX architecture according to the present invention. In the embodiment shown in fig. 2, the VPX-architecture multi-unit server is used as a technical verification platform, and the whole system is divided into three layers, namely a common layer (Utility Plane), a Management Plane (Management Plane) and a Data Plane (Data Plane): the common layer mainly refers to common signals, power supply, etc., and in some embodiments of the present invention, the power supply voltage of the common layer is + 12V; the management layer mainly manages control signals for the IPMB; the data layer is primarily SRIOX4 high speed data transfer signals.

Each computer unit has 2 paths of SRIOX4 interfaces, which are connected with 2 switching units SRIO switching paths respectively, and a data layer double star structure is formed on the 2 switching units. The hardware architecture of 2 switching units is completely the same, and can carry out different slot position replacement, but the working mode has the branch of master-slave, the default that the slot position number is small is the master switching unit, the default that the slot position number is large is the slave switching unit. When the master control exchange unit works normally, only the master control exchange unit carries out data distribution and system state management, once the master node fails, the slave control exchange unit obtains the failure state of the master control exchange unit through a data path and a management path between the two exchange units and takes over the functions of the master control exchange unit and the air exchange unit actively.

As shown in fig. 2, the data layer and the management layer are designed based on a dual star redundant topology, the working method is similar, and the data layer is taken as an example to explain the embodiment: in some embodiments of the present invention, in a data layer, each switching unit provides 10 external SRIOX4 interfaces, where 8 external SRIOX4 interfaces are respectively connected to 8 computers, 1 external SRIOX interface is connected to a post-switching unit, and 1 external SRIOX interface is used for interconnecting two switching units, so as to form all paths of a dual-star structure and complete interconnection and intercommunication between 2 star structures.

In some embodiments of the present invention, during normal operation, data enters the main control switching unit from the outside through the data add-drop unit, the main control switching unit performs packet processing and distribution on the data, and distributes the data to 8 computer units through the SRIO data path, the computer units process the received data, and send the processed data to the main control switching unit, and the data is transmitted to the outside through the data add-drop unit after switching.

In the embodiment of the invention, the temperature in the system is increased after a large amount of data operation, and therefore, a reserved unit is arranged in the system, is mainly used for cooling the system, and can also be used as a standby position for emergency supplement of each unit.

Because the switching unit is used as a system core main control unit, the ambient temperature of the switching unit is higher, and the performance of the switching unit is negatively influenced when the switching unit is in a high-temperature environment for a long time. For this purpose, the reservation unit is preferably arranged close to the switching unit.

In some embodiments of the present invention, the backplane is selected to be a high-speed interconnect backplane with a higher thermal capacity, so that data transmission is safer.

According to the embodiment of the blade reinforcing server system based on the VPX architecture, the slave control switching unit responds to the normal operation of the master control switching unit, maintains the standby state and monitors whether the master control switching unit fails.

In some embodiments of the present invention, the slave switching unit is always in a standby state although the data path is connected to the master switching unit and the computer unit, and continuously monitors the health state of the master switching unit in the standby state. When the master control exchange unit fails, the slave control exchange unit acquires the fault information of the master control exchange unit through a data path between the master control exchange unit and the slave control exchange unit, and actively takes over the data transmission and distribution functions of the master control exchange unit, so that the data transmission is not affected, the high-reliability data transmission is realized, and the function failure and data loss of the whole product are effectively avoided.
