What architecture feature allows for increased storage utilization without adding additional compute resources?

The concept of scale-up architecture is centered around enhancing the performance and capacity of existing resources rather than adding new ones. This architecture allows an organization to increase storage utilization by vertically upgrading the existing storage systems. By scaling up, organizations can add more disks or memory within the current storage environment, utilizing the existing compute resources more efficiently.

This approach optimizes storage needs without the complexity and cost associated with integrating additional compute resources. It can lead to a more straightforward management process while ensuring that the data storage is maximized in terms of both performance and capacity. Thus, the architecture feature that promotes increased storage utilization in this manner is indeed scale-up architecture.
