Dell Compellent Automated Tiered Storage – Data Progression
The Dell Compellent Storage Center Storage Area Network (SAN) provides a highly efficient and flexible
foundation for enterprise and the cloud. Dell Compellent storage features an innovative Dell Fluid
Data architecture to put the right data in the right place at the right time. It enables the storage
system to dynamically adapt the changing business environment.
Dell Compellent Storage Center provides a fully virtualized storage platform that includes:
Storage virtualization that abstracts and aggregates all resources across the entire array,
providing a high-performance pool of shared storage.
Thin provisioning and automated tiered storage to deliver optimum disk utilization and
intelligent data movement.
Space-efficient snapshots and thin replication for continuous data protection without wasted
capacity.
Built-in automation and unified storage management to streamline storage provisioning,
management, migration, monitoring and reporting.
Dell Compellent pioneered the automated storage tiering solution in its Storage Center products in
2004. The Data Progression feature (Figure 2) delivers sub-LUN automated storage tiering to move
data dynamically, intelligently, and efficiently among multiple storage tiers and RAID levels. Data
Progression is a licensed feature that leverages cost and performance differences between storage
tiers, allowing the maximum use of lower cost and higher capacity SATA or SAS (7.2K RPM) drives for
stored data, while maintaining performance oriented SSD drives, Fibre Channel or SAS (15K RPM) drives
for frequently-accessed data.
