Scale-up is a method in which additional disk enclosures are added to existing storage systems to cope with increasing data volumes.

• A. True
• B. False
• C. Not sure
• D. Both

Answer: (A)

Scale-up storage expands capacity by adding more disks within the same storage system, typically through additional disk enclosures connected to the existing controllers. This approach increases total capacity (and can boost I/O via more disks under the same control plane) as data volumes grow. The given statement describes exactly that: adding disk shelves to an existing array to cope with increasing data, which is the essence of scale-up. This is in contrast to scale-out, where new independent storage nodes are added to share workload. So the statement is true.
