Buffer Tenure Management for Data Storage Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data storage systems face performance bottlenecks and inefficiencies due to the varying physical and performance characteristics of different types of data memory, which complicates the management and transfer of data across multiple memory types.
Innovation Solution
A buffer manager that intelligently directs data between on-chip and off-chip buffers based on predicted and actual data tenure, optimizing data transfer and storage performance by leveraging the efficient characteristics of each memory type.

Engineering Contradiction Analysis
1Speed
If data is stored in on-chip buffer, then data access speed is improved, but buffer capacity is limited
Solution Approach 1:
The buffer system is segmented into multiple buffers with different characteristics (on-chip buffers for speed, off-chip buffers for capacity). The buffer manager divides data storage tasks across these segmented buffers based on data tenure requirements, allowing the system to simultaneously achieve fast access for short-term data and large capacity for long-term data.
2Productivity
If data is transferred frequently between buffers, then optimal performance is maintained, but system complexity increases
Solution Approach 1:
The buffer management system is dynamic rather than static. The buffer manager continuously monitors data tenure characteristics and dynamically adjusts data placement and transfer decisions. This dynamic approach optimizes performance by transferring data only when necessary (e.g., when tenure threshold is exceeded) rather than following a fixed schedule, reducing unnecessary transfers while maintaining optimality.
Solution Approach 2:
The system incorporates feedback mechanisms where the buffer manager monitors data access patterns, tenure characteristics, and buffer status. Based on this feedback, the buffer manager makes intelligent decisions about data placement and transfer timing, adapting to changing workloads and optimizing performance without requiring complex manual management.
3Productivity
If buffer tenure management is implemented, then data storage efficiency is improved, but management overhead is increased
Solution Approach 1:
The buffer management system operates autonomously without requiring external intervention. The buffer manager automatically monitors data tenure, determines optimal buffer placements, and executes data transfers based on predefined policies and observed data characteristics. This self-service capability improves storage efficiency through intelligent management while keeping overhead manageable by eliminating the need for complex external control mechanisms.

AI summary
A data storage device with one or more buffers can employ buffer tenure management with at least a data storage device having a first buffer, a second buffer, a buffer manager, and a non-volatile memory. The first buffer can be located on-chip while the second buffer is located off-chip. The first buffer may be filled with data having a tenure of less than a predetermined tenure threshold as directed by the buffer manager.
