Difference between Rack servers and Blade Servers

The main difference between rack server blade server is A Rack Server is an independent server installed in the case, while Blade Servers need to work with each other in one chassis.

When it comes to cabling huge network connections, Servers are usually considered to manage these networks effectively. Coming to Servers, there are three types of servers classified on the basis of their structure. These Servers are Rack serversTower servers, and blade servers. We are going to talk about Rack servers and Blade servers and what are the distinct features which differentiate among the two.

Rack Servers

Rack Servers are the rack-mounted servers that could specifically be fitted in a server rack. Rack Servers are the servers that are made with efficient configurations to support a wide range of requirements.

They are also known for their shape and structure as unlike traditional servers shaped in a PC structure, it is much wider and flatter which could be fit into any server rack. Rack servers are considered beneficial if there’s a requirement of a small number of servers as they pose low upfront costs being highly economical

Rack servers benefit in minimizing the space consumption as they can be mounted one over the other.

Rack Servers Features

  • Rack server acts as the lone rider of all the needed components as a single powerful system. Rack servers could perform powerfully to run high-end applications.
  • Rack servers are convenient to fit as it consumes less amount of physical space.
  • Rack servers are usually equipped with internal fans, increasing airflows which makes it’s cooling more easier.
  • Rack servers can be highly efficient when you require more than one server as they don’t require a huge chassis.

Blade Server

Blade servers are those servers that can accommodate multiple servers in a smaller area. These servers usually have a thin like structure having just the CPUs, memory, integrated network controllers, and sometimes storage drives built-in. 


These servers also manage their chassis according to their components required. Because of their thin like structure, blade servers can be conveniently fitted into one single rack along with providing high processing power


Blade servers require fewer internal components as on a larger chassis, multiple blade servers can be slided and fitted to operate efficiently. 


These servers are capable to be used when there are higher computing requirements along with some type of Enterprise Storage System like NAS or SAN. Blade servers provide that kind of architecture that allows you to scale a higher processor density.

Blade Server Features

  • Blade servers can enable their massive chassis to supply power to multiple servers which reduces total power consumption for each blade server.
  • Blade servers promote Hot-swappable features which could provide you redundancy when one blade faces a problem making it to be pulled and replaced much more easily.
  • Blade servers require only one cable (often fiber) for running to the chassis which reduces the use of individual cables running for each blade server.
  • Blade servers require minimal space and at the same time provide high processing power.

Going through the above concepts of Rack servers and Blade servers, it would be difficult to frame out which one is the best as both of these servers have the same set of functionalities and working. It is particularly, based on your processing needs and layout of your physical space along with considering the thermal and electrical power requirements of your machine and other computing requirements which could let you to decide among the two.

Serverstack is one of the leading brands in dealings of Rack servers and provides you the efficient servers of ASUS helping you to manage your huge network connections easily.
