Detailed Description
The core of the invention is to provide an NVMe disk hot plug management method and related components of the NVMe backboard, so that servers using different platforms can use the same NVMe backboard, resource waste caused by repeated development is avoided, and development and operation cost is reduced.
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a flowchart of an NVMe disk hot plug management method of an NVMe backboard according to the present invention, the method includes:
s11, a first CPLD on an NVMe backboard acquires the type of a platform running on a server;
s12, detecting whether a first CPLD stores NVMe disk hot-plug data transmission strategies corresponding to the type of the platform, wherein the first CPLD stores the NVMe disk hot-plug data transmission strategies corresponding to a plurality of types of platforms in advance, and the positions of bit signals of the NVMe disks in hot-plug data corresponding to different NVMe disk hot-plug data transmission strategies in the hot-plug data are different, if yes, entering S13;
and S13, when the NVMe disk is plugged in or pulled out from an NVMe disk interface on the NVMe backboard, corresponding hot plug data are sent to a CPU (central processing unit) of a main board in the server according to an NVMe disk hot plug data transmission strategy corresponding to the type of the platform, so that the CPU uses the NVMe disk according to the hot plug data.
When platforms running on the server are different, the hot plug data transmission strategies of the NVMe disk are also different, so that different platforms cannot directly use the same NVMe backboard.
In order to solve the above technical problem, first, a first CPLD (Complex Programmable Logic Device ) on an NVMe backplane stores in advance NVMe disk hot plug data transmission policies corresponding to multiple types of platforms, for example, NVMe disk hot plug data transmission policies storing platforms such as Intel, AMD (Advanced Micro Devices, super-power semiconductor), ARM (Advanced RISC Machine, advanced RISC microprocessor), and homemade Loongson, which is not particularly limited in the present application.
And secondly, the first CPLD can acquire the type of the platform running on the server so as to facilitate the subsequent detection of whether the first CPLD has an NVMe disk hot plug data transmission strategy corresponding to the type of the platform running on the server. Because the CPU on the main board of the server needs to carry out data transmission with the NVMe disk, the CPU needs to know whether the NVMe disk is in place or not, and when the NVMe disk is in place, the CPU can establish connection with the NVMe disk and carry out data transmission; when the NVMe disc is out of place, the CPU is temporarily disconnected from the NVMe disc and no data transmission is performed. Therefore, the first CPLD needs to send the in-place signal of the NVMe disc to the CPU, and the transmission strategies of the hot plug data of the NVMe discs for transmitting the in-place signal of the NVMe discs by different platforms are different, for example, the hot plug data are all 8 bits, one hot plug data can only control one corresponding NVMe disc, the 5 th bit in the hot plug data of some platforms is used for transmitting the in-place signal of the NVMe disc, but the 6 th bit in the hot plug data of other platforms is used for transmitting the in-place signal of the NVMe disc, so that the transmission strategies of the hot plug data of the NVMe discs of different platforms are different, and therefore different platforms cannot use the same NVMe backboard. According to the invention, the first CPLD stores the NVMe disk hot-plug data transmission strategies corresponding to a plurality of types of platforms in advance, and if the first CPLD has the NVMe disk hot-plug data transmission strategies corresponding to the types of the platforms running on the server, when the NVMe disk is plugged in or pulled out from the NVMe disk interface, the NVMe disk hot-plug data transmission strategies corresponding to the types of the platforms are executed, so that the NVMe disk can be replaced under the condition that the server is started to run under the condition that different platforms are used.
It should be noted that, the hot plug data includes, in addition to the in-place signal of the NVMe disc, a signal of which position the hot plug data specifically controls the NVMe disc.
In summary, the invention can enable servers using different platforms to use the same NVMe backboard, avoid resource waste caused by repeated development, and reduce development and operation cost.
