Automated Storage Tiering
Meet service level requirements by optimizing the utilization of HDDs, SSDs, and RAID levels

Overview:

By enabling users to flexibly assign applications to four available tiers distinguished by different drive types and RAID levels, automated storage tiering provides an architecture that fully leverages the advantages of different storage media, including SSDs for high-performance data storage. With automated storage tiering, users can greatly optimize storage performance and increase ROI.

As part of automated storage tiering, data is migrated between tiers based on data usage patterns and user-configured policies. With tiering implemented on the sub-volume level, data can be moved in a highly granular fashion. Data migration achieves efficient distribution of data, and ensures that SSDs and other high-performance drives have the necessary storage space to deal with mission-critical applications.

Benefits:

Features	Benefits
Fine-tuning storage deployment	By assigning applications to different tiers consisting of different drive types and RAID levels, users can easily meet wide variety of service level requirements
Optimized storage performance	SSDs are used most efficiently in an automated storage tiering architecture to optimize performance by up to 150% at no additional costs compared to a non-tiered configuration
Enhanced ROI	Optimized performance available at no additional costs or lower costs By precisely meeting service level requirements, storage can be efficiently utilized Efficient storage utilization increases lifespan
Flexible capacity deployment	While enjoying higher performance and reduced costs, capacity can be increased by deploying high-capacity nearline drives in lower tiers
Highly efficient data migration	Based on data usage patterns, migration ensures optimized distribution of data in storage pools Sub-volume tiering ensures highly granular data movement Scheduling options ensure data migration can be conducted based on actual user requirements Ensures SSDs have the necessary space to serve mission-critical applications
Efficient storage utilization	Doing more with less reduces storage footprint and lowers power consumption SSDs feature low power consumption levels
Simplified management	Automated features help IT managers spend much less time on assigning applications to storage media and migrating data
