SYSTEM FOR MONITORING AND CONTROLLING HOST SELECTION FOR A MULTI-HOST CAPABLE PCI-E DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18075475 titled 'SYSTEM FOR MONITORING AND CONTROLLING HOST SELECTION FOR A MULTI-HOST CAPABLE PCI-E DEVICE
The storage system described in the patent application utilizes multiple CPU hosts and PCI-E multi-host capable devices, with link selection controllers to map shared memory addresses to individual PCI-E links. This ensures that each address is accessed through only one of several PCI-E links, improving efficiency and performance.
- Addresses are grouped into same-size segments, each containing addresses mapped to the same PCI-E link.
- Link selection controllers monitor for state changes affecting PCI-E link availability.
- In case of a failure, the controllers coordinate a response that includes re-mapping affected addresses.
Potential Applications: - High-performance storage systems - Data centers - Cloud computing infrastructure
Problems Solved: - Efficient utilization of PCI-E links - Improved performance and reliability in storage systems
Benefits: - Enhanced data access speed - Increased system reliability - Optimal resource utilization
Commercial Applications: "Optimizing Data Access in High-Performance Storage Systems: Market Implications"
Prior Art: There may be prior art related to link selection controllers in storage systems, but further research is needed to determine specific examples.
Frequently Updated Research: Stay updated on advancements in PCI-E multi-host capable devices and link selection technologies for storage systems.
Questions about the Technology: 1. How does the use of link selection controllers improve data access in storage systems? 2. What are the key advantages of grouping memory addresses into segments for PCI-E link mapping?
Original Abstract Submitted
A storage system that includes multiple CPU hosts and PCI-E multi-host capable devices uses link selection controllers to map shared memory addresses to individual PCI-E links such that each address is accessed via only one of a plurality of PCI-E links. The addresses may be grouped into same-size segments, each of which contains only addresses mapped to the same PCI-E link. The link selection controllers monitor for state changes that affect PCI-E link availability and, in response to detection of a failure, coordinate a response that includes re-mapping the affected addresses.
