Advantages of Blade Servers

A.

Blade servers and rack-mount servers are two common types of servers used in data centers. Blade servers are a type of server that fits multiple independent server modules (known as blades) into a single chassis, while rack-mount servers are standalone servers that are installed in a rack.

The advantage of blade servers over rack-mount servers can vary depending on the specific use case, but one common advantage is a decreased number of servers per rack. This is because blade servers are designed to pack more computing power into a smaller space than rack-mount servers. As a result, a single blade server chassis can house many more server modules than a single rack-mount server.

Reduced power consumption is also a common advantage of blade servers. Since blade servers can fit more computing power into a smaller space, they can often achieve higher computing densities than rack-mount servers. This can result in lower power consumption and reduced cooling costs.

Enhanced virtualization support is another potential advantage of blade servers. Blade servers are often designed with features specifically aimed at supporting virtualization, such as integrated network and storage connectivity, and shared cooling and power supplies. This can make it easier to deploy and manage virtualized environments, which are becoming increasingly common in modern data centers.

Increased security is not typically considered an advantage of blade servers over rack-mount servers. While it is true that blade servers can be configured with various security features, such as hardware-based encryption or secure boot, these features are not unique to blade servers and can also be found in rack-mount servers.

Therefore, the correct answer to this question is C. Decreased number of servers per rack.
