Automated Storage Tiering 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.   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
