For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The application provides a method for isolating data transmission faults, which is applied to a processor in a server, wherein the server also comprises a first bus and a second bus which are both connected with the processor, referring to fig. 1, fig. 1 is a schematic structural diagram of the method for isolating data transmission faults, and the method comprises the following steps:

Specifically, when the bus is idle (other devices are all connected to the bus in a high impedance state) and one device is to communicate with the destination device, the device initiating the communication drives the bus, issuing the address and data. Other devices connected to the bus in a high impedance state receive the data on the bus if they receive (or are able to receive) address information corresponding to themselves.

determining a virtual partition corresponding to the physical partition according to the information of the virtual partition corresponding to the physical partition in the fault control signal;
and allocating the physical partition which is free of faults and in an idle state to the virtual partition, wherein the size of the physical partition which is free of faults and in the idle state is not smaller than the size of the virtual partition.
5. The method of isolating a data transmission failure of claim 4, wherein a size of the physical partition that is free of failure and in an idle state is equal to a size of the virtual partition.
6. The method of isolating a data transmission failure of claim 1, further comprising:
and the control prompt module prompts the information of the physical partition.
7. The method for isolating a data transmission failure according to any of claims 1 to 6, wherein reassigning a new physical partition to a virtual partition corresponding to the physical partition according to the failure control signal comprises:
determining a virtual partition corresponding to the physical partition according to the information of the virtual partition corresponding to the physical partition in the fault control signal;
determining standby physical partitions except the physical partitions corresponding to the virtual partitions according to the mapping relation between the preset physical partitions and the virtual partitions;
a new physical partition is selected from the spare physical partition to be allocated to the virtual partition.
8. An apparatus for isolating data transmission failures, comprising:
a memory for storing a computer program;
a processor for implementing the steps of the method of isolating a data transmission failure according to any of claims 1 to 7 when said computer program is executed.
9. A computer readable storage medium, characterized in that it has stored thereon a computer program which, when executed by a processor, implements the steps of the method of isolating a data transmission failure according to any of claims 1 to 7.
10. A server comprising the server itself and further comprising the means for isolating data transmission failures of claim 8.
