Dell EMC Exam DEE-1111 Topic 1 Question 4 Discussion

The feature of PowerMax and VMAX All Flash arrays that provides ORM functionality is write coalescing. ORM stands for Optimized Resource Management, which is a set of technologies that optimize the performance and efficiency of flash storage. Write coalescing is one of the ORM technologies that reduces the write amplification and extends the life of flash drives. Write coalescing combines multiple small writes into larger sequential writes before destaging them to the flash drives. This reduces the number of write operations and the amount of data that needs to be erased and rewritten on the flash drives, which improves the performance and endurance of the flash storage.
