Ratcheting Up Global Namespace Performance
Download as PPT, PDF0 likes462 views
The document discusses using centralized storage caching to improve the performance of global namespaces in NAS environments. Centralized caching can accelerate global namespaces by handling high-volume operations from cache, reducing load on file servers and allowing low-volume operations to still access files. This improves namespace performance and scalability when expanding clients and file servers using a shared global namespace across multiple file systems.
