STRIPE MANAGEMENT METHOD, STORAGE SYSTEM, STRIPE MANAGEMENT APPARATUS, AND STORAGE MEDIUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18151848 titled 'STRIPE MANAGEMENT METHOD, STORAGE SYSTEM, STRIPE MANAGEMENT APPARATUS, AND STORAGE MEDIUM

Simplified Explanation

The present disclosure is about methods and systems for managing stripes in storage systems. It introduces a new approach to stripe management using erasure codes. Here are the key points:

  • The patent application describes a method for managing stripes in a storage system.
  • Stripes are groups of data units and check units that are stored across multiple storage devices.
  • The method involves obtaining check units from a plurality of stripes, where each stripe has a different erasure code ratio.
  • A new check unit is generated based on the check units from the different stripes.
  • The new check unit and data units from the different stripes are combined to form a new stripe.
  • The new stripe has a different erasure code ratio than the original stripes, with more data units.
  • The quantity of data units corresponding to the first erasure code ratio is less than the quantity of data units corresponding to the second erasure code ratio.

Potential applications of this technology:

  • This stripe management method can be applied in various storage systems, such as cloud storage, data centers, and distributed file systems.
  • It can improve the efficiency and reliability of data storage and retrieval processes.
  • The method can be used to optimize storage capacity and performance in large-scale storage systems.

Problems solved by this technology:

  • Traditional stripe management methods may not efficiently utilize storage capacity or provide sufficient fault tolerance.
  • This technology addresses these issues by dynamically generating new stripes with different erasure code ratios, optimizing data storage and recovery.

Benefits of this technology:

  • Improved storage efficiency by dynamically adjusting the erasure code ratio based on the data units and check units.
  • Enhanced fault tolerance by generating new check units and combining them with data units from different stripes.
  • Increased storage capacity by utilizing more data units in the new stripe compared to the original stripes.


Original Abstract Submitted

The present disclosure relates to stripe management methods, storage systems, stripe management apparatuses, and storage mediums. In one example method, check units in a plurality of stripes are obtained. A first stripe of the plurality of stripes complies with a first erasure code ratio. A new check unit is generated based on the check units in the plurality of stripes. The new check unit and data units in the plurality of stripes belong to a new stripe, the new stripe complies with a second erasure code ratio, and a quantity of data units corresponding to the first erasure code ratio is less than a quantity of data units corresponding to the second erasure code ratio.
