MULTI-DOMAIN AND MULTI-TIER SCALE-OUT ARCHITECTURE FOR CLUSTERED FILE SYSTEMS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17877132 titled 'MULTI-DOMAIN AND MULTI-TIER SCALE-OUT ARCHITECTURE FOR CLUSTERED FILE SYSTEMS
Simplified Explanation
Embodiments of a multi-domain and multi-tier architecture for clustered network file systems are described in this patent application. The system allows users to create sub-clusters of physical nodes called domains, and file system resources are allocated only from the nodes within each domain. This limits the impact of system failures to the files within a specific domain. A file system redirection service manages a global namespace that spans the domains and redirects file accesses to the appropriate domain where the file is stored. Each domain has different classes of storage tiers with varying cost and performance characteristics. Files can be placed on different tiers based on a storage level agreement (SLA) specified for each file. Examples of tiers include a higher performance tier consisting of SSDs and a lower performance tier of HDDs.
- Users can create sub-clusters of physical nodes called domains.
- File system resources are allocated only from the nodes within each domain.
- System failures only impact the files within a specific domain.
- A file system redirection service manages a global namespace and redirects file accesses to the appropriate domain.
- Different classes of storage tiers with varying cost and performance characteristics are available in each domain.
- Files can be placed on different tiers based on specified storage level agreements (SLAs).
- Examples of tiers include SSDs for higher performance and HDDs for lower performance.
Potential applications of this technology:
- Clustered network file systems for large-scale data storage and management.
- Distributed file systems for cloud computing environments.
- High-performance computing clusters requiring efficient file access and management.
Problems solved by this technology:
- Minimizes the impact of system failures on file availability by limiting failures to specific domains.
- Provides a scalable and flexible architecture for managing large-scale file systems.
- Allows for efficient file access and management across multiple domains and tiers.
Benefits of this technology:
- Improved fault tolerance and reliability by isolating system failures to specific domains.
- Enhanced performance and cost optimization by placing files on appropriate storage tiers.
- Scalable and flexible architecture for managing large-scale file systems.
- Efficient file access and management across multiple domains and tiers.
Original Abstract Submitted
Embodiments are described for a multi-domain and multi-tier architecture for clustered network file systems. This system allows a user to create sub-cluster of physical nodes, called domains, and file system resources for the data placed in a domain are allocated only from the nodes in the domain. It limits the impact of system failures to the files within a domain. A file system redirection service manages a global namespace spanning the domains and redirects file accesses to the appropriate domain where it is stored. In each domain, there are different classes of storage, tiers, with different cost and performance characteristics. Files can be placed on a set of tiers depending on a storage level agreement (SLA) specified for a file. Tier examples include a higher performance tier consisting of SSDs and a lower performance tier of HDDs.
