1. A system, comprising:

  • a rack;

    a data storage module coupled to the rack, the data storage module comprising;

    a first backplane;

    at least one first mass storage device coupled to the first backplane;

    at least one second backplane;

    at least one second mass storage device coupled to the at least one second backplane; and

    a control device configured to;

    access status information indicating;

    a first current temperature of at least one of the first backplane or the at least one first mass storage device;

    a second current temperature of at least one of the at least one second backplane or the at least one second mass storage device;

    determine that the first current temperature exceeds a first threshold temperature and that the second current temperature does not exceed the first threshold temperature;

    responsive to the first current temperature exceeding the first threshold temperature, emit at least one signal to cause a shutdown of the at least one first mass storage device coupled to the first backplane while the at least one second mass storage device remains operative; and

    subsequent to the shutdown of the at least one first mass storage device;

    responsive to a determination that the first current temperature is greater than a second threshold temperature and less than the first threshold temperature, wherein the second threshold temperature is less than the first threshold temperature, maintain the shutdown of the at least one first mass storage device; and

    responsive to a determination that the first current temperature is less than the second threshold temperature, emit at least another signal to cause a restart of the at least one first mass storage device.
