DATA RETENTION EVENT PREPARATION/RECOVERY SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240303167 titled 'DATA RETENTION EVENT PREPARATION/RECOVERY SYSTEM

The patent application describes a data retention event preparation/recovery system that includes a chassis, multiple NAND subsystems within the chassis, and a data retention event preparation/recovery subsystem connected to the NAND subsystems.

  • The data retention event preparation/recovery subsystem identifies NAND subsystems at risk of a data retention event, locates overprovisioned blocks within the NAND subsystems, and transfers data from vulnerable NAND subsystems to the overprovisioned blocks before powering off the NAND subsystems to initiate the data retention event.

Key Features and Innovation:

  • System for preparing for and recovering from data retention events in NAND subsystems.
  • Identification of at-risk NAND subsystems and transfer of data to overprovisioned blocks.
  • Efficient and proactive approach to managing data retention events in storage systems.

Potential Applications:

  • Data centers
  • Enterprise storage systems
  • Cloud storage providers

Problems Solved:

  • Mitigating data loss during data retention events in NAND subsystems.
  • Improving the reliability and resilience of storage systems.

Benefits:

  • Enhanced data protection and integrity.
  • Minimized risk of data loss.
  • Improved system performance and longevity.

Commercial Applications:

  • Data storage companies can offer more reliable and secure storage solutions to their customers.
  • Technology companies can integrate this system into their storage products to enhance data protection.

Questions about Data Retention Event Preparation/Recovery System: 1. How does the system determine which NAND subsystems are at risk of a data retention event? 2. What are the advantages of transferring data to overprovisioned blocks before a data retention event occurs?

Frequently Updated Research: Research on advancements in NAND technology and data retention event management in storage systems may provide insights into further improvements in this area.


Original Abstract Submitted

a data retention event preparation/recovery system includes a chassis, a plurality of nand subsystems included in the chassis, and a data retention event preparation/recovery subsystem that is included in the chassis and coupled to the plurality of nand subsystems. the data retention event preparation/recovery subsystem determines that the plurality of nand subsystems will experience a data retention event and, in response, identifies a first subset of the plurality of nand subsystems that exceed an error threshold, identifies at least one overprovisioned block in the plurality of nand subsystem, copies data that is stored on the first subset of the plurality of nand subsystems to the at least one overprovisioned block in the plurality of nand subsystems, and power offs the plurality of nand subsystems to begin the data retention event.
