Dell Compellent Thin Provisioning delivers the highest enterprise storage utilization possible by eliminating pre-allocated but unused capacity. The software, Dynamic Capacity, completely separates allocation from utilization, enabling users to provision any size volume upfront yet only consume disk space when data is written. Thin Write technology assesses the incoming payload and designates capacity for each write on demand, leaving unused disk space in the storage pool for other servers and applications.


How to Optimize Disk Utilization with Dynamic Capacity

Eliminate the pre-allocated but unused disk capacity inherent to traditional network storage systems
Expand volumes online and add capacity on the fly to accommodate change without disruption or downtime

Convert legacy volumes to virtual volumes when introducing them to the storage pool using Thin Import
Use Free Space Recovery to reclaim disk space after files are deleted in Windows? environments
Automate storage consumption monitoring and trend analysis with capacity threshold alerts and history reports

Reduce the capacity needed to store existing data up to 40% when migrating to Dell Compellent

戴爾康貝的精簡配置通過消除預分配空間實現(xiàn)了最高的存儲利用率。動態(tài)空間軟件把分配和使用分離開來，使得用戶可以預先建立任意大小的卷，只在有數(shù)據(jù)寫入時才會消耗磁盤空間。精簡配置技術評估寫入負載并按需為每次寫入分配空間，將未使用的磁盤空間留在存儲池供其他服務器和應用使用。


怎樣用動態(tài)空間優(yōu)化磁盤使用？

消除預分配空間。
windows系統(tǒng)下，在文件被刪除后回收磁盤空間。
自動的監(jiān)控存儲消耗并進行趨勢分析，作出容量極限警報和歷史報表。
數(shù)據(jù)遷移到戴爾康貝后，容量需求降低達40%。
