OPERATION METHODS OF STORAGE DEVICES, AND OPERATION METHODS OF STORAGE SYSTEMS INCLUDING HOSTS AND STORAGE DEVICES - A simplified explanation of the abstract
This abstract first appeared for US patent application 17864653 titled 'OPERATION METHODS OF STORAGE DEVICES, AND OPERATION METHODS OF STORAGE SYSTEMS INCLUDING HOSTS AND STORAGE DEVICES
Simplified Explanation
The patent application describes an operation method for RAID (Redundant Array of Independent Disks) systems. RAID is a technology that combines multiple disk drives into a single logical unit to improve data storage performance and reliability.
- The method involves generating RAID parity data in response to a RAID enable request and a write request from an external host.
- The RAID enable request includes a stream identifier and a RAID enable indication, indicating the start of RAID operation.
- The write request includes the stream identifier and the data to be written.
- The first data and the RAID parity data are stored based on the stream identifier, ensuring data redundancy and fault tolerance.
- A second write request with a different stream identifier triggers the storage of second data.
- The method also allows for the disabling of RAID operation through a RAID disable request, which includes the stream identifier and a RAID disable indication.
Potential applications of this technology:
- Data storage systems: The method can be applied in various data storage systems that utilize RAID technology, such as servers, network-attached storage (NAS), and storage area networks (SAN).
- Cloud computing: RAID systems are commonly used in cloud computing environments to ensure data availability and reliability. This method can enhance the performance and fault tolerance of cloud storage systems.
Problems solved by this technology:
- Data redundancy: The method addresses the need for redundant data storage to protect against disk failures and data loss.
- Stream-based organization: By using stream identifiers, the method allows for efficient organization and retrieval of data based on different write requests from the external host.
Benefits of this technology:
- Improved data reliability: The use of RAID parity data and redundancy ensures that data can be recovered in case of disk failures.
- Enhanced data performance: RAID systems can improve data access and transfer speeds, leading to faster data processing and retrieval.
- Simplified management: The method provides a streamlined approach to enable and disable RAID operation, making it easier to manage and maintain RAID systems.
Original Abstract Submitted
Disclosed is an operation method including generating RAID parity data based on first data in response to an RAID enable request and a first write request, the RAID enable request and the first write request being received from an external host, the RAID enable request including a first stream identifier and a RAID enable indication, and the first write request including the first stream identifier and the first data, storing the first data and the RAID parity data based on the first stream identifier, storing second data based on a second stream identifier in response to receiving a second write request from the external host, the second write request including the second stream identifier and the second data, and receiving an RAID disable request from the external host, the RAID disable request including the first stream identifier and a RAID disable indication.
