An HPE 3PAR StoreServ customer with FC, SSD and NL, drives is facing extreme latency...

To address extreme latency during peak business hours for an OLTP application, using Dynamic Optimization between tier 0 (typically the fastest storage tier, such as SSDs) and tier 1 (slightly slower but still high-performance drives) can significantly improve performance. Dynamic Optimization allows for the non-disruptive movement of volumes between different tiers of storage, ensuring that the most performance-critical data resides on the fastest available storage during peak times. This strategy optimizes storage performance and ensures that OLTP workloads meet required performance levels.
