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 Servers ‘think’ they have all the storage they want…storage they want…

……but they only get what they but they only get what they need.need.

Flexible Virtual Storage

Auto-Provisioning Saves Time and Effort Traditional Disk Provisioning 1. Determine which Application is

running out of space2. 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

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
