What should an IS auditor do when they notice continuous addition of storage resources in IT infrastructure?

When an IS auditor observes the continuous addition of storage resources in the IT infrastructure, reviewing the capacity management process is essential. This action facilitates the understanding of how effectively the organization is managing its resources, ensuring that storage is used efficiently and aligned with current and future needs. Capacity management involves monitoring and evaluating current usage patterns, forecasting future needs, and implementing policies and procedures to optimize resource utilization.

By focusing on the capacity management process, the auditor can identify whether the ongoing increase in storage is a response to growing data needs, inefficiencies, or potentially unregulated growth. This insight can lead to improved strategies for resources allocation, cost management, and performance optimization, ensuring that the IT infrastructure remains responsive to the organization's requirements.

In contrast, the other options, while they may have relevance in specific contexts, do not directly address the underlying reason behind the continuous addition of storage. For instance, recommending disk mirroring focuses on data redundancy rather than addressing capacity management directly. Similarly, reviewing offsite storage adequacy pertains to backup strategies rather than the efficiency of current capacity utilization. Finally, suggesting a compression algorithm may help with space savings but does not resolve the fundamental capacity management issues or strategic planning associated with resource allocation.
