Which of the following is a recommended method for optimizing storage in a data center environment?

Implementing data compression and deduplication are fundamental techniques for storage optimization. Data deduplication eliminates redundant copies of data, storing only one unique instance. Data compression reduces the size of data by encoding it using fewer bits. Together, these methods significantly decrease the physical storage capacity required, reducing capital and operational expenditures, and improving overall data center efficiency. These are core features of modern storage arrays designed for optimization.

A. Adding more storage without analyzing usage leads to overprovisioning and increased costs, which is the opposite of optimization.
B. Not monitoring storage usage prevents informed decision-making, making it impossible to identify and implement effective optimization strategies.
D. Leaving storage capacity at maximum levels is a form of overprovisioning that wastes resources and increases operational costs unnecessarily.

1. HPE Primera OS 4.2 Technical White Paper. This document details the storage efficiency features of HPE Primera. Section: "Data reduction," Page 7, states, "HPE Primera data reduction technologies include... Zero-detect, Deduplication, Compression, and Data-packing." This confirms that deduplication and compression are key HPE optimization methods.
