Automated Tiered Storage
Data Progression™
Dell Compellent Fluid Data storage dynamically moves enterprise data to the optimal storage tier based on actual use. The most active blocks reside on high-performance SSD, Fibre Channel or SAS drives, while infrequently accessed data migrates to lower-cost, high-capacity SAS drives. The result is network storage that remains in tune with application needs, with overall storage costs cut by up to 80%.
How to Optimize Enterprise Storage with Data Progression
- Automated tiering eliminates manual data classification and migration while lowering drive counts and power/cooling costs
- Write active blocks of data to Tier 1 storage with performance-optimized RAID levels such as RAID 10
- Automatically migrate inactive blocks of data to lower-tier storage with higher-overhead, high-protection RAID 5 or 6
- Mix SSD, FC and SAS drives in the same system, and SAS drives with varied rotational speeds in the same enclosure
- Deploy SSDs to maximize write performance and data availability for mission-critical applications
- Automatically restripe volume data across all drives when adding capacity on demand
