What concept relates to the scale-out feature of Network-Attached Storage?

The scale-out feature of Network-Attached Storage (NAS) primarily relates to enhancing cost-efficiency. Scale-out architectures allow for the addition of more storage nodes to the existing system as demand increases, instead of having to replace or augment existing equipment with bigger, potentially more expensive alternatives. This flexibility enables organizations to expand their storage capacity in a more gradual and controlled manner, leading to cost savings overall.

By utilizing a scale-out approach, businesses can align their expenditures with their actual storage needs, avoiding the pitfalls of over-provisioning. This also allows for better resource utilization, as storage can grow incrementally while managing costs effectively. This makes NAS a compelling option for businesses looking to scale their storage solutions sustainably and economically.

In contrast, improving complexity, increasing physical footprint, and decreasing overall performance do not align with the benefits typically associated with the scale-out feature, as scale-out designs strive to maintain efficiency and performance while simplifying management and deployment.
