AI Technical Summary
Technical Problem
In existing distributed storage systems, metadata servers become a bottleneck, limiting system size and scalability, and hash mapping methods restrict the flexibility of data block distribution and storage balance.
Method used
Data blocks are managed using placement groups (PGs). Data blocks are allocated to placement groups through a metadata service, and placement group information is cached on the client side, reducing the load and interaction of the metadata service and enabling flexible storage resource management.
Benefits of technology
It enhances the scalability of distributed storage systems, reduces the load on metadata services, and improves storage resource utilization and the flexibility of data block location management.
