Ratcheting Up Global Namespace Performance

  1. 1. Ratcheting Up Global Namespace Performance with Centralized Storage Caching
  2. 2. NAS and SAN Architectures File System 1 File System 1 File System 2 File System 3 Block-based SAN device File-based NAS device SAN Architecture NAS Architecture System 3 Space System 2 Space System 1 Space
  3. 3. NAS Lends Itself To Client Growth and Sharing File System 1 File-based NAS device Easily add clients with shared file system approach Eventually, new NAS devices are required, but they maintain unique file systems and must be managed independently 2 3
  4. 4. Global Name Spaces Ease NAS Expansion File-based NAS devices Global Name Space Easily add clients with global namespace approach Easily add file servers with global namespace approach File System 1 File System 2 File System 3 File System 4 File System 5 File System n
  5. 5. Caching and Namespace Performance Low Latency IOPS Throughput Global Namespace Disks Shared Namespace File System Performance Capacity Namespace performance Memory Caching performance
  6. 6. Walking the Directory Tree Global Namespaces Can Add to Performance Concerns Requested content: dog.file /quick /brown /fox /jumped Sample NFS directory lookup / quick / brown / fox / jumped / over / the / lazy / dog.file Additional NFS operation
  7. 7. Centralized Storage Caching Accelerates Global Name Spaces Application Servers Scalable Caching Appliance NFS File Systems with Global Namespace <ul><li>Legend </li></ul><ul><ul><li>High volume operations from cache </li></ul></ul><ul><ul><li>Low volume operations to/from filers </li></ul></ul>
