  • 2. What is Storage Virtualization ? Pooling of physical Storage Devices Single Storage Pool Better Storage Utilization Simplified Storage Management Dynamic Allocation of Capacity Virtual What You Want Logical Pool Reality Virtualization Layer What You Have Physical Systems © 2008 NetApp. All rights reserved. 2
  • 3. Reasons for Storage Virtualization VM1 VM2 VM3 Moving to Virtualized Servers Storage Challenges Storage Opportunities Need cost-effective storage Pools of shared storage Storage reliability becomes Data deduplication critical Simplified DR across all Server-based backups no applications longer practical Common physical & virtual Need rapid storage storage environment provisioning for VMs © 2008 NetApp. All rights reserved. 3
  • 4. Controller-based Virtualization First Choice CIFS / NFS FC SAN Multi Protocol Controller File Services Virtualization Consolidation of File- and iSCSI Block-Workloads within common system – NFS, CIFS – iSCSI, FCP Support of heterogenous NetApp storage Arrays HDS Arrays IBM Arrays Fujitsu Arrays 3PAR Arrays HP Arrays EMC Arrays © 2008 NetApp. All rights reserved. 4

  • 8. Thin Provisioning Allows to „oversubscribe“ physical diskspace LUNs and Volumes do not contain data immediately when created Typically filled with data over time Physical diskspace is really needed when data is written to LUN „Buy storage when it is really needed !“ © 2008 NetApp. All rights reserved. 8
