Question
What is the Deduplication Management Object (DMO) used for with PowerMax Deduplication?
A. Identifies identical data patterns based on the Hash ID
B. Inline process using the same data reduction module as the Adaptive Compression Engine
C. Stores and manages pointers between front-end devices and a single instance of data stored on disk
D. Representation of data in a deduplication relationship
Answer
C. Stores and manages pointers between front-end devices and a single instance of data stored on disk
Explanation
C. The Deduplication Management Object (DMO) in PowerMax Deduplication stores and manages pointers between front-end devices and a single instance of data stored on disk. It enables data deduplication by maintaining a mapping between the logical block addresses (LBAs) of the front-end devices and the physical location of the deduplicated data on the back-end storage. This allows multiple front-end devices to share the same physical data, reducing storage consumption.
