  • 1. A Tale of New Choices Increasing Performance of Existing NAS Installations
  • 2. Background Information
    • Network Attached Storage (NAS) market at 77% year-over-year growth*
    • More customers looking to scalable, performance-oriented NAS solutions
      • Isilon, IBRIX, BlueArc, NetApp Ontap GX
    • NAS users moving towards transactional applications
      • More than 5,000 enterprises worldwide use the Oracle® on NetApp solution*
    • Source: NetApp news release 15 November 2006
  • 3. Large Installed Base NAS Market Share Most NAS Deployments from NetApp and EMC Source: NetApp Analyst Day 2006: http://www.netapp.com/go/analyst2006/presentations/ad2006-danw.pdf
  • 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
