A company needs a solution that provides storage only as needed. The company's goal is to reduce capital expenditures and lower the power and cooling overhead to reduce operating expenditures. Which t

Thin provisioning allocates virtual capacity on demand but still relies on existing physical storage hardware and does not inherently reduce the underlying CapEx or the power and cooling footprint.

Scale-out storage arrays expand capacity by adding physical nodes over time, which increases both capital expenditures and the number of devices consuming power and cooling.

Scale-up storage servers grow by adding shelves or components to a single chassis, directly increasing hardware spend and physical resource consumption rather than reducing them.

Virtual storage arrays (VSAs) are software-defined storage solutions that run on standard x86 servers rather than requiring purpose-built dedicated storage hardware, directly reducing capital expenditures. By consolidating storage functions into software on shared infrastructure, the number of physical devices requiring power and cooling is reduced, lowering operating expenditures. Storage is provisioned on-demand as needed, meaning physical resources are only consumed as workloads require them, fulfilling the requirement to provide storage only as needed.
