Question
A PowerMax systems administrator has created three storage groups with the diamond, gold, and silver service levels. How does the system ensure the service level response times are met during heavy workloads?
A. By throttling the host front-end IOs
B. Service levels are identical on All Flash systems
C. By allocating more device cache slots to Diamond
D. By throttling the back-end IOs
Answer
A. By throttling the host front-end IOs
Explanation
By throttling the host front-end IOs.
During heavy workloads, the PowerMax system ensures service level response times are met by throttling host front-end I/Os. This prioritizes I/O requests from storage groups with higher service levels (Diamond) over those with lower service levels (Gold and Silver). Throttling front-end I/Os allows the system to maintain the desired response times for critical workloads while limiting the impact of less important ones.
