Blade servers are designed for extreme density, allowing many individual server modules to fit into a single chassis that occupies minimal rack U-space. This design shares power supplies, cooling, and network connections across multiple servers, making it ideal for installing fifteen servers, along with redundant UPSs, a network switch, and a KVM, within a single 14U rack.

Rackmount servers typically consume 1U, 2U, or more per server, making it impractical or impossible to fit 15 individual rackmount servers plus other components into a single 14U rack.

Tower servers are standalone units not designed for rack mounting and would be an inefficient and inappropriate choice for a rack-based, high-density server deployment.

Web servers describe a server's functional role or application purpose, not its physical form factor, and therefore is not relevant to the question of physical installation density.
