Dynamic Capacity™

Thin Provisioning That Improves Capacity Utilization

Compellent's Thin Provisioning, called Dynamic Capacity, delivers the highest storage utilization possible by eliminating allocated but unused capacity. Dynamic Capacity completely separates storage allocation from utilization, enabling users to allocate any size virtual volume upfront yet only consume actual physical capacity when data is written by the application. And, with Compellent’s Thin Import and Free Space Recovery, you can extend the benefits of Dynamic Capacity to convert legacy volumes into thin provisioned data or optimize space utilization in Windows® environments.

Compellent's Thin Provisioning eliminates the allocated, but unused capacity of traditional storage allocations, allowing you to:

Reduce Disk Spending.
Delay future storage purchases and leverage storage price erosion by better utilizing disk storage upfront and adding disks incrementally as needed. Buy up to 50 percent less drives when importing data from legacy systems.

Automate Time Intensive Capacity Planning Activities.
Spend less time provisioning storage, expanding and assigning volumes, and manually tracking volume utilization. Advanced monitoring and trending further simplifies capacity planning. Automatically reclaim deleted file space in a Windows® OS.

Increase Availability and Performance.
Expand volumes online; utilizing actual instead of allocated disk space improves all volume-level operations such as copy, replication and rebuild.

Key Benefits

Reduce storage costs by delaying storage purchases and eliminating allocated but unused disk space typical for businesses
Save administrative time by automating common management tasks including capacity planning
Increase availability by eliminating downtime due to volume expansion
Improve performance by creating smaller volumes and writing only actual data
Support a greater number of servers without additional storage capacity
Reduce the space, power and cooling costs of maintaining allocated but unused capacity
Assign capacity to allow for future growth without having the physical disk in your SAN
Eliminate the wasted capacity of legacy storage when importing data
Automatically reclaim space in Windows® OS

The Compellent Advantage

Compellent	Others Typically
Assign any application disk capacity for future growth without having the physical disk in your SAN	Force you to over purchase resulting in wasted capacity
Volume expansion performed on-line at any time	Require you to shut down data access to make changes
Scale from 1 TB to 100 TB on the same product platform	Require a forklift upgrade to different product line to grow capacity
Reduces disk drive requirements by up to 50 percent and help IT departments reclaim storage resources	Copy existing data ‘as is’ causing space to be wasted when converting to a new SAN
Enables the unused space from a Thin Provisioned volume to be utilized again	Continue to report that the space is unavailable after Windows files are deleted from a thin provisioned volume
