Which of the following BEST describes a server where several physical server chassis are housed within an enclosure to share some redundant resources?
Click on the arrows to vote for the correct answer
A. B. C. D.C.
The server type that is described in the question is a blade server (option C).
Blade servers are a type of server that allows multiple server modules (or blades) to be housed within a single chassis or enclosure. These blades share some of the resources, such as power and cooling, that are redundant across the chassis. Each blade is essentially a self-contained server with its own CPU, memory, storage, and networking interfaces.
Blade servers are designed to be space-efficient and easy to manage, as they allow for high-density computing with minimal cabling and reduced power consumption. Blade servers also typically offer a high level of availability and scalability, as the modular design allows for easy expansion or replacement of individual blades.
In contrast, a tower server (option A) is a standalone server that resembles a traditional desktop computer in form factor. These servers are typically used in small offices or homes, and are not designed for high-density computing or rack-mounting.
A rack mount server (option B) is a server that is designed to be mounted in a standard rack cabinet, along with other servers and networking equipment. Rack mount servers are typically larger than blade servers and offer more internal space for expansion and customization.
Finally, a bare metal server (option D) is a server that is dedicated to running a single operating system or application. These servers typically have no virtualization layer or other software installed, and are designed to provide high performance for specific workloads.
