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

戴尔康贝的精简配置通过消除预分配空间实现了最高的存储利用率。动态空间软件把分配和使用分离开来，使得用户可以预先建立任意大小的卷，只在有数据写入时才会消耗磁盘空间。精简配置技术评估写入负载并按需为每次写入分配空间，将未使用的磁盘空间留在存储池供其他服务器和应用使用。


怎样用动态空间优化磁盘使用？

消除预分配空间。
windows系统下，在文件被删除后回收磁盘空间。
自动的监控存储消耗并进行趋势分析，作出容量极限警报和历史报表。
数据迁移到戴尔康贝后，容量需求降低达40%。
