A datacenter is running out of rack space. A server technician is asked to recommend a capacity planning and consolidation option that is feasible with the least amount of downtime. Which of the…

Replacing internal storage with SAN addresses storage architecture, not server count or rack space density.

Tower servers are floor-standing standalone units that consume more physical space than rack-mounted servers and are unsuitable for datacenter rack consolidation.

Replacing rack-mount servers with tower servers would worsen space consumption because tower servers require separate floor space rather than fitting into existing racks.

Blade servers share a single chassis that provides centralized power, cooling, and networking for many individual blade modules, dramatically increasing compute density per rack unit compared to traditional 1U or 2U rack servers. Workloads can be migrated to blades progressively, minimizing downtime during consolidation. This directly addresses the rack space shortage by replacing multiple discrete servers with a single high-density chassis.
