What is a Blade Server?

A Blade Server consists of a chassis containing multiple thin, modular electronic circuit boards, known as server blades, with each blade being dedicated to a single application. Each blade contains processors, an optional Fibre Channel host bus adaptor (HBA), integrated network controllers and other input/output (IO) ports.

Allowing for more processing power in less rack space, Blade Servers simplify cabling and help to reduce power consumption. As less cabling is required for blade installations in comparison to Rack and Tower Servers, this significantly reduces the amount of time spent managing the infrastructure, and instead enables more time ensuring high availability.

What are Blade Servers used for?

Blade servers are typically used in a clustering of servers and function well when they are dedicated to a single task, such as:

  • File sharing
  • Web hosting
  • Virtualization
  • Cluster computing
  • Web page serving and caching
  • Streaming audio and video content
  • SSL encrypting of web communication
  • The transcoding of web page content for smaller displays

Advantages & Disadvantages of Blade Servers

Blade Servers are the newest and the most advanced type of servers in the market. The biggest advantage of Blade Servers is that they are the smallest types of servers available and are great for conserving space.


Size and form-factor: Blades are the smallest and the most compact servers, requiring minimal physical space. They allow more processing power in less rack space, simplifying cabling and reducing power consumption.

Simpler cabling: Businesses moving to blade servers can experience up to an 85% reduction in cabling for blade installations over conventional 1U or tower servers, according to a SearchWinSystems.com article on server technology.

Less time spent on IT management: With so much less cabling, IT administrators can spend less time managing the infrastructure and more time ensuring high availability. Also, in a blade server, you can connect all the blades through a single interface, making the maintenance and monitoring easy.

Load balancing and failover: With Blade Servers having a simpler and smaller infrastructure, load balancing among the servers and failover management is generally much simpler.

More likely to overheat: Blade Servers are very powerful and come with high component density compared to rack and towers servers. Therefore, heating, ventilation, and air conditioning systems must be managed well to prevent overheating.

Expensive configuration: Although upgrading the blade server is easy to handle and manage, the initial configuration or the setup might require heavy efforts in complex environments.

However, Techbuyer’s free configure-to-order service makes CTO servers simple. We can build any blade server to your exact specification, so you can experience easy installation upon arrival.
