STORAGE DEVICE AND AN OPERATING METHOD OF A STORAGE CONTROLLER THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 17967626 titled 'STORAGE DEVICE AND AN OPERATING METHOD OF A STORAGE CONTROLLER THEREOF

Simplified Explanation

The abstract describes an operating method for a storage controller that involves receiving a permanent write protection command and checking the distribution of data in a specific namespace. Based on certain metrics related to non-volatile memory devices, the method sets one or more memory regions as protected memory regions. It then migrates a portion of the data stored in a different memory region to the protected memory region.

  • The method involves a storage controller receiving a permanent write protection command.
  • The distribution of data in a target namespace is checked.
  • Based on metrics related to non-volatile memory devices, one or more memory regions are designated as protected memory regions.
  • A portion of the data stored in a memory region other than the protected memory region is migrated to the protected memory region.

Potential Applications

  • This technology can be applied in various storage systems, such as solid-state drives (SSDs) or storage area networks (SANs).
  • It can be useful in scenarios where certain data needs to be permanently write-protected for security or compliance reasons.

Problems Solved

  • The method addresses the need for permanent write protection of specific data in a storage system.
  • It solves the problem of efficiently distributing and migrating data to designated protected memory regions.

Benefits

  • The method provides a way to permanently protect specific data from being overwritten or modified.
  • It allows for efficient migration of data to protected memory regions, ensuring data integrity and security.
  • By utilizing metrics related to non-volatile memory devices, the method optimizes the allocation of protected memory regions.


Original Abstract Submitted

An operating method of a storage controller includes receiving a permanent write protection command; checking a distribution of first data included in a target namespace corresponding to the permanent write protection command; setting at least one memory region as a protected memory region, based on at least one metric corresponding to each of a plurality of non-volatile memory devices; and migrating at least a portion of the first data, which is stored in a remaining memory region different from the protected memory region, to the protected memory region
