Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems face performance bottlenecks in data read and write operations due to inefficient interaction with storage devices, particularly in handling large data volumes and requiring additional processing steps that impact latency and throughput.
Innovation Solution
The implementation of a system that allows applications to directly interact with memory devices through a portable operating system interface (POSIX), bypassing the storage stack, using Non-Volatile Memory Express (NVMe) over Fabric (NVMe-oF) and persistent memory over Fabric (PMEMoF) protocols, enabling in-line deduplication, error detection, data protection, and encryption while maintaining transparent data management across a scalable storage pool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If applications interact with storage devices through the storage stack, then data management and security features are provided, but data access latency increases and throughput decreases
Solution Approach 1:
The system segments the storage architecture into two paths: a high-performance path using NVMe-oF for latency-sensitive operations and a managed path using the storage stack for security and data management. This segmentation allows applications to bypass the storage stack for time-critical data access while still utilizing its services when needed.
Solution Approach 2:
The patent introduces an intermediary layer (NVMe-oF interface) that mediates between applications and storage devices, enabling direct access while maintaining connection to the storage stack for security and management functions. This intermediary allows simultaneous access to both performance and management capabilities.
2Reliability
If additional processing steps are implemented for data security and management, then data protection is enhanced, but system throughput decreases
Solution Approach 1:
Security and management features are pre-configured and cached in the NVMe-oF interface, allowing data to be accessed directly without real-time processing through the storage stack. Encryption keys, access controls, and management policies are established beforehand, enabling high-speed data transfer without compromising security.
Solution Approach 2:
The system maintains continuous data protection capabilities through the NVMe-oF path by pre-establishing security contexts and maintaining encrypted channels, allowing data protection to operate continuously without interrupting the high-speed data flow that would otherwise require batch processing through the storage stack.
3Speed
If the storage stack is bypassed for direct memory access, then data access performance improves, but data management capabilities are reduced
Solution Approach 1:
The NVMe-oF interface is designed with multi-functionality, serving both as a high-performance data access path and as a manager of data security and storage operations. This universal interface consolidates multiple functions into a single component that can handle both speed-critical and management-critical operations.
Solution Approach 2:
The system implements feedback mechanisms where the NVMe-oF interface continuously monitors data access patterns and automatically adjusts management operations, caching strategies, and security contexts. This feedback loop ensures that the bypassed path maintains full data management capabilities through intelligent automation rather than manual intervention.
Data Source
AI summary
A method for storing data, the method comprising receiving, by an offload component in a client application node, a request originating from an application executing in an application container on the client application node, wherein the request is associated with data and wherein the offload component is located in a hardware layer of the client application node, and processing, by the offload component using an advanced data services pipeline, the request by a file system (FS) client and a memory hypervisor module executing in a modified client FS container on the offload component, wherein processing the request results in at least a portion of the data in a location in a storage pool.
