Since the inception of storage devices that used multiple drives for a single volume, the topic of RAID configuration and storage pools has been highly debated. Designing and maintaining the proper design could be time consuming and the wrong decisions could have a negative impact on performance. In addition, reconfiguring the storage layout often required considerable planning.
PowerStoreOS uses the capabilities of flash-based storage for maximum performance and capacity, eliminating the need for administrators to configure RAID or storage pools. Most existing SQL Server publications that discuss RAID levels and configuration were written based on older technology and apply to spinning drives. Therefore, these concepts do not apply to PowerStore. Dell Technologies recommends following the guidance in this paper and associated publications for best performance and availability.
