For a cloud service provider using HPE 3PAR StoreServ 9000, Priority Optimization is the recommended solution to ensure the quality of service (QoS) and protect tenants from unpredictable bursts of I/O from other tenants. Priority Optimization allows administrators to set service levels for different workloads, ensuring that critical workloads receive the necessary resources while maintaining overall system performance. This feature helps manage and enforce QoS in a multi-tenant environment, providing predictable performance and preventing noisy neighbors from impacting other tenants.
