A Tale of New Choices

  1. 1. A Tale of New Choices Increasing Performance of Existing NAS Installations
  2. 2. Background Information <ul><li>Network Attached Storage (NAS) market at 77% year-over-year growth* </li></ul><ul><li>More customers looking to scalable, performance-oriented NAS solutions </li></ul><ul><ul><li>Isilon, IBRIX, BlueArc, NetApp Ontap GX </li></ul></ul><ul><li>NAS users moving towards transactional applications </li></ul><ul><ul><li>More than 5,000 enterprises worldwide use the Oracle® on NetApp solution* </li></ul></ul><ul><li>Source: NetApp news release 15 November 2006 </li></ul>
  3. 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. 4. A Tale of New Choices <ul><li>Many customers enjoy their current NAS solutions but need greater scalability and performance. </li></ul><ul><li>Today’s choices: </li></ul><ul><ul><li>Change entire architecture </li></ul></ul><ul><ul><li>Change storage architecture </li></ul></ul><ul><li>New choice: </li></ul><ul><ul><li>Complement current configuration </li></ul></ul>1 2 3
  5. 5. Typical Enterprise NAS Configuration Application Servers Network Controller Storage “disk shelves” <ul><li>Scenario </li></ul><ul><li>Stable NAS configuration </li></ul><ul><li>Comfort with current procedures, operating system, and management software </li></ul><ul><li>Requirements </li></ul><ul><li>Need additional IOPs </li></ul><ul><li>Need lower latency </li></ul>
  6. 6. Change Choice 1: New architecture throughout Application Servers (software drivers) Network Controller Storage “disk shelves” <ul><li>Required upgrades </li></ul><ul><li>Controller heads </li></ul><ul><li>Disk shelves </li></ul><ul><li>Suggested upgrades </li></ul><ul><li>Server-side drivers </li></ul><ul><li>Other Impacts </li></ul><ul><li>New file system </li></ul><ul><li>New data management software </li></ul><ul><li>New backup/recovery software </li></ul><ul><li>Training and Installation </li></ul>Parallel file system with new back-end storage, and server side drivers
  7. 7. Change Choice 2: Change storage architecture Application Servers Network Integrated Clustered NAS <ul><li>Required upgrades </li></ul><ul><li>Controller heads </li></ul><ul><li>Disk shelves </li></ul><ul><li>Other Impacts </li></ul><ul><li>New file system </li></ul><ul><li>New data management software </li></ul><ul><li>New backup/recovery software </li></ul><ul><li>Training and Installation </li></ul>Clustered file system and full storage hardware change out
  8. 8. New Choice: Complement and Extend Existing Servers Existing Network Existing Controllers Existing Storage Accelerated storage through centralized storage caching <ul><li>Required hardware change out </li></ul><ul><li>None </li></ul><ul><li>Benefits </li></ul><ul><li>Retain current file system </li></ul><ul><li>Retain current data management software </li></ul><ul><li>Receive immediate performance increase with existing architecture </li></ul>Scalable Caching Appliance
  9. 9. Before and After Centralized Storage Caching <ul><li>Before: </li></ul><ul><ul><li>Performance boost required infrastructure change-out </li></ul></ul><ul><li>After: </li></ul><ul><ul><li>Complement infrastructure with scalable caching appliances </li></ul></ul><ul><ul><ul><li>Retain existing NFS storage </li></ul></ul></ul><ul><ul><ul><li>Stick with proven storage operating systems </li></ul></ul></ul><ul><ul><ul><li>Maintain current data management practices </li></ul></ul></ul><ul><ul><ul><ul><li>Snapshot, Backup, Recovery, Provisioning, Access Control, Replication </li></ul></ul></ul></ul><ul><ul><ul><li>Avoid massive over-provisioning of disk-based solutions </li></ul></ul></ul><ul><ul><ul><li>Achieve superior performance with high-speed, centralized cache </li></ul></ul></ul>
