What is a blade server?
The Blade server is a compact computer server that is designed to work with the blade or stand on the server. A computer server is a computer designed to provide services and support multiple users in the network. Each individual blade is a firmly compressed unit for computer processing. The blades are designed to work with the stand because they do not have their own strength, cooling or protective covers.
The blade stand looks like a metal library. The blades can be inserted horizontally or vertically, depending on the design selected for the stand. All power and mains cables are connected to the stand and not with individual blades. This is because of the built -in connectors that fit exactly in the back of the Blade server. Many stands have a glass front door that prevents dust and has thick cooling fans built into the upper and lower part.
These fans are used to maintain temperature at a suitable level for all Blade servers. Blade racks are usually stored in SERver rooms, which have built -in cooling capacity, reserved power source and air filters. The Blade server has three components: memory, processor and storage. All other items such as hard drives, fans, power cables, etc., are removed and are built into the stand or separate location. This shift in the design significantly reduces the required space, allowing the same space to support greater computer processing capacity.
Cooling is the main problem for Blade servers. First generation servers would exceed the cooling capacity of standard server rooms with blades at 50 % capacity. The need to build space around each unit for air circulation has reduced the capacity of the economical space of these units. Modern blades have a better design and a standard stand can hold up to 128 blades at once.
Another advantage of blade setting is increased network efficiencyThe inside of the stand is all the blades connected to one or more network buses. This reduces the total costs because there is no need for the relationship between the server and the network bus.
Storage problems for setting up the Blade server are solved using external storage services and alternative connections. This functionally allows you to store hard drives in another place. In the company size setting, a storage or SAN network for managing all data and application software is created. This source is accessible using reserved network connections and can actually increase the performance of the system.
