Many NAS customers need greater scalability and performance than their current solutions provide, but do not want the disruption of replacing their entire storage architecture. A new option allows them to complement their existing NAS configuration with scalable caching appliances. This provides an immediate performance increase without requiring changes to file systems, data management software, or other elements of their existing storage architecture.

4. A Tale of New Choices Many customers enjoy their current NAS solutions but need greater scalability and performance. Today’s choices: Change entire architecture Change storage architecture New choice: Complement current configuration 1 2 3

5. Typical Enterprise NAS Configuration Application Servers Network Controller Storage “disk shelves” Scenario Stable NAS configuration Comfort with current procedures, operating system, and management software Requirements Need additional IOPs Need lower latency

6. Change Choice 1: New architecture throughout Application Servers (software drivers) Network Controller Storage “disk shelves” Required upgrades Controller heads Disk shelves Suggested upgrades Server-side drivers Other Impacts New file system New data management software New backup/recovery software Training and Installation Parallel file system with new back-end storage, and server side drivers

7. Change Choice 2: Change storage architecture Application Servers Network Integrated Clustered NAS Required upgrades Controller heads Disk shelves Other Impacts New file system New data management software New backup/recovery software Training and Installation Clustered file system and full storage hardware change out

8. New Choice: Complement and Extend Existing Servers Existing Network Existing Controllers Existing Storage Accelerated storage through centralized storage caching Required hardware change out None Benefits Retain current file system Retain current data management software Receive immediate performance increase with existing architecture Scalable Caching Appliance

9. Before and After Centralized Storage Caching Before: Performance boost required infrastructure change-out After: Complement infrastructure with scalable caching appliances Retain existing NFS storage Stick with proven storage operating systems Maintain current data management practices Snapshot, Backup, Recovery, Provisioning, Access Control, Replication Avoid massive over-provisioning of disk-based solutions Achieve superior performance with high-speed, centralized cache
