Advanced Storage Tiering. Having seen the benefits of expanded storage tiers, EMC will continue to implement a tiered/shared model. The plan is to automate data movement between tiers and selectively use solid-state disk for applications that require high performance. Dense, affordable SATA disk will continue to be the standard otherwise. EMC plans to implement Fully Automated Storage Tiering (FAST) for automated, policy-based data movement, which will help streamline storage costs and maximize resource utilization. By using Symmetrix V-Max storage and PowerPath Virtual Edition on VMware vSphere clusters with FAST, EMC expects to increase the storage utilization rate from 68% to.
