NVMf Protocol Server Startup Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current server system startup methods using iSCSI protocol are inefficient due to slow read and write speeds and high storage access latency, affecting the overall performance of servers without local hard disks in cloud computing environments.
Innovation Solution
A server system starting method utilizing NVMf protocol for communication between a host and a network card, enabling faster data reading and lower access latency by obtaining mirror image data for the root file system from a storage cluster, which reduces storage access latency and improves startup efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If iSCSI protocol is used for network storage communication, then server systems can access storage clusters without local hard disks, but data read/write speeds are slow and storage access latency is high
Solution Approach 1:
The patent changes the communication protocol parameter from iSCSI to NVMf, which fundamentally alters the data transmission mechanism. NVMf uses NVMe over Fabrics with RDMA technology, changing how data is accessed and transmitted over the network, thereby achieving faster read/write speeds and lower latency without requiring local hard disks
2Adaptability or versatility
If servers use network storage clusters instead of local hard disks, then cloud computing scalability is improved, but system startup efficiency deteriorates due to slow mirror image data retrieval
Solution Approach 1:
The patent changes the storage access protocol parameter to NVMf, which enables faster retrieval of mirror image data during system startup. This protocol change maintains the scalability benefits of network storage while dramatically improving startup efficiency through optimized data transmission and access mechanisms
3Reliability
If iSCSI protocol is used for storage access, then compatibility with existing storage systems is maintained, but overall server performance deteriorates
Solution Approach 1:
The patent changes the communication protocol parameter from iSCSI to NVMf, which provides better performance characteristics while maintaining compatibility through standardized interfaces. The NVMf protocol preserves storage system compatibility while enabling faster data access and improved server overall performance
Data Source
AI summary
The embodiments of the present disclosure relate to a server system starting method, apparatus, electronic device and storage medium. A host sends a block device access request to a network card for obtaining mirror image data corresponding to a root file system based on a NVMf communication connection; the network card obtains the mirror image data corresponding to the root file system from a target storage node of a storage cluster, and sends the mirror image data corresponding to the root file system to the host based on the NVMf communication connection; the host mounts the root file system to complete system startup.
