Description
Technical Field
The invention belongs to the technical field of servers, and particularly relates to a method and a system for quickly switching Expander configuration.
Background
In the design of the server SAS Expander, in order to adapt to different application scenarios, a plurality of firmware versions of different versions are designed and developed in the same hardware system, and different functions are realized by swiping different firmware. The SAS expanders collocated with firmware of different versions cannot be distinguished from the appearance because of sharing a hardware design scheme, and in order to avoid mixed use in production and use, the SAS expanders of each firmware version can independently correspond to one PCBA number.
The SAS Expander firmware is burned in a memory named as EMMC, an internal memory space of the EMMC can be divided into a plurality of partitions, and the partitions can be used for burning the same firmware as backup. Two burning modes are usually adopted, and the SAS Expander is usually produced by using the offline mode, so that the burning mode is simple and convenient for large-scale processing; the other is online burning, and the SAS Expander installed in the server can burn new firmware in band through Host, or burn new firmware out of band through debug interface carried by the main IC of the SAS Expander.
For the finished SAS Expander needing to switch configuration, new firmware is generally burned in the following two ways, the first way is an in-band burning way, the SAS Expander in the server is installed with relevant tools under an OS, and then corresponding firmware files are selected to be burned in an instruction way, so that the burning speed is high; the second mode is an out-of-band burning mode, and new firmware is burned by connecting the firmware of the notebook computer through a debug interface of the SAS Expander main IC and a debug tool. Although the two burning modes can realize firmware burning of the finished product SAS Expander, the efficiency is too low compared with the method for burning offline in batch; for the sold server, if the client wants to modify the configuration without replacing the Expander, the online burning mode will affect the time efficiency of modifying the configuration, so that the client satisfaction is reduced, and the large-scale one-time deployment cannot be realized. This is a technical problem in the prior art.
