Final answer:
The primary concern during the systems architect's design stage for a new data center encompasses equipment type, data center location, and power specifications. All of these must be considered together as they are interconnected and essential for the detailed design of the data center's architecture.
Step-by-step explanation:
During the design stage, a systems architect must address several critical factors, including equipment type, data center location, and power specifications. Each element is significant and interdependent, influencing the design architecture, which involves assigning functional elements of the data center to the physical components. The primary concern is ensuring that these factors collectively support the data center's requirements and constraints. Equipment type will determine the technology and capabilities of the data center; power specifications will guide the infrastructure's ability to support the equipment, and the location can influence several aspects like connectivity, accessibility, and environmental considerations.
Since these elements are fundamentally intertwined in the design process, it is imperative to consider them holistically. Therefore, the correct answer, reflecting the major concerns in this stage of the process, would be 'All of the above.' Each decision may have ramifications on the others, and as such, design decisions should be made with a comprehensive understanding of how each aspect impacts the overall design and function of the data center.
