Compellent’s Automated Tiered Storage….and what it means to you
One of the standout features in Compellent’s long list of great features is their Data Progression. What it does is autonomously classify and move data at the block level between tiers of storage based on frequency of use.
This has several benefits, all of them big:
- Save money by storing inactive data on cheaper, larger capacity drives
- Improve the overall SAN performance by keeping only high-traffic data on the faster drives
- Reduce administrative overhead by doing all of this autonomously - no intervention required
Surprisingly, most midrange SAN’s out there do not do this out of the box like Compellent; usually requiring either manual transfer of data between tiers or a 3rd party software layer which adds cost and complexity.
