Zone write distribution method and system based on ZNS solid state disk

The invention provides a zone write distribution method and system based on a ZNS solid state disk. The method comprises the steps that S1, a WDM core monitors the number of active zone resources andthe number of idle super block resources of each LKM core at the rear end in real time; s2, the WDM c...

Summary:The invention provides a zone write distribution method and system based on a ZNS solid state disk. The method comprises the steps that S1, a WDM core monitors the number of active zone resources andthe number of idle super block resources of each LKM core at the rear end in real time; s2, the WDM core obtains the LKM core with the largest number of active zone resources and the LKM core with thesmallest number of active zone resources in all the LKM cores, and calculates the difference value of the active zone resources of the LKM core and the LKM core; s3, the WDM core obtains the LKM corewith the largest number of the real-time idle super block resources and the LKM core with the smallest number of the real-time idle super block resources in all the LKM cores, and calculates the difference value of the idle super block resources; and S4, when the WDM core receives the write distribution task of the front-end DM core, balancing is performed according to the active zone resource difference value and the idle
