2 Auto Serving Capacity: Thin-Provisioning Very large virtual disk assigned to each server Small fraction of real capacity allocated to each virtual disk DataCore automatically allocates additional space when used Servers ‘think’ they have all the storage they want… …but they only get what they need. Flexible Virtual Storage

3 Auto-Provisioning Saves Time and Effort Traditional Disk Provisioning 1.Determine which Application is running out of space 2.Determine how to add storage (extend Volume/LUN, add LUN, etc.) 3.Determine how much storage to add. 4.Determine where to get storage. 5.Allocate storage from Pool. 6.Set protection (LUN masks) for Applications to see correct storage. 7.Set switch zoning and HBA settings if applicable. 8.Add storage to App. LUN or create new App. LUN Note: Typically requires reboots and downtime 9.Perform Volume formatting, Volume Management, Configure OS and Apps. to be able to use the larger LUN or new LUN 10.Replenish Pool (add disks) DataCore Automates the Process 1.Create a virtual volume 2.Drag and Drop the volume on the server channel 3.Apply SANmelody does the rest

9 Free Space Free Space Free Space Free Space Wasted Capacity Wasted Capacity Wasted Capacity Downtime Virtual Volumes Current approach: Causes downtime Wastes storage resources Expensive to scale and manage DataCore’s approach: Automate common tasks Maximize asset utilization Grow resources gracefully Manage centrally Automate Capacity - Thin Provisioning

10 Go Green with DataCore! Thin Provisioning Allocate-On-Write (Use only when needed) On average, deploy only 1TB for every 2.5TB required with traditional storage arrays Reduce Power & Cooling Reduce Carbon Footprint by 60% Tiered Storage Match storage needs to application requirements Archive to less power-consuming drives Replication Changed blocks only; minimize capacity utilization Consolidation & Optimal Utilization Eliminate SAN islands; reduce power consumption
