Which of the following server chassis types allows for the HIGHEST server density in a rack?

Blade servers are designed for maximum density, fitting many individual server modules (blades) into a single chassis that occupies a small number of rack units. This design shares power, cooling, and networking components, optimizing space.

A tower server converted for rack use is inherently inefficient with space, offering poor density due to its original design not being optimized for rack mounting.

Tower servers are standalone units not designed for rack mounting and therefore provide the lowest server density in a rack environment.

While rack servers are designed for racks and offer good density (e.g., 1U or 2U form factors), blade servers achieve higher density by consolidating multiple server nodes within a shared chassis.
