Problems solved by technology
Many devices now use 4-way wide link, which allows up to 4 narrow ports to be aggregated into one wide port. If the cable is faulty or aging, the link cannot be connected, which may cause the entire system to be unstable or paralyzed.
[0003] Currently, multiple SAS cable links directly out of the same wide port, if the cable lengths are not uniform, or if the rate of a certain cable is too much and the rate is reduced, the rate of several links will be inconsistent and the link will be disconnected
The normal operation of the system cannot be guaranteed when the rates of several links are inconsistent

The present invention provides a speed balancing method, system, terminal and storage medium of a hub cable, comprising: collecting the transmission rates of multiple hub cables at a hub port; confirming that the transmission link where the hub port is located is abnormal, then Screen the minimum transmission rate from the transmission rates of multiple hub cables; determine whether the minimum transmission rate is lower than the rate lower limit threshold of the hub cable: if yes, output a cable fault prompt; if not, then output The transmission rates of all the hub cables of the hub port are adjusted to the minimum transmission rate. The present invention guarantees that the whole system can run by adjusting the speed, and guarantees the running of the system while gaining time for maintenance personnel to solve problems, and reduces the risk of data loss.
Description
technical field [0001] The present invention relates to the technical field of storage data transmission, in particular to a method, system, terminal and storage medium for balancing the rate of a hub cable. Background technique [0002] With the continuous acceleration of digitization, the application of the storage industry will grow explosively. The basis of data storage is a collection of a large number of hard disks. In the process of building a storage system, it is necessary to use a sas cable to connect the JBOD / JBOF in series through the sas port. Many devices now use 4-way wide links, allowing up to 4 narrow ports to be aggregated into a wide port. If the sas on a link is running during system operation The failure or aging of the cable causes the link to fail, which may cause the entire system to become unstable or paralyze the entire system. [0003] Currently, for multiple SAS line links going straight out of the same wide port, if the line lengths are not unif...
