In this article, we will explain about Cisco UCS License or Cisco servers. Cisco has been working in the field of server equipment, switches and routers for many years and is one of the most well-known companies that every year it also records very high sales statistics.
Other well-known companies in the field of server construction include HPE or DELL EMC and others.
What is Cisco UCS?
Anyone who works with data centers and networks is familiar with Cisco router equipment and switches. As we mentioned, these products are very popular all over the world and it can be said that almost all organizations and small and large companies use this equipment in their network. In addition, Cisco works in the field of server equipment, and Cisco servers are known as UCS, which are used in data centers.
Cisco servers have special and modern features. In the following, we will first get acquainted with the physical architecture of Cisco UCS License servers and Cisco licenses, in order to have a better understanding of this equipment.
Why UCS is the right choice!
Undoubtedly, reduction in current costs is one of the most important issues for any company. One of the features of licensed Cisco UCS is I/O pooling. By consolidating I/O, infrastructure costs for companies are reduced.
In addition, UCS has the ability to connect I/O networks to the infrastructure. Using this technology, it is possible to connect 20 blade chassis. Based on this feature, 80 Gbps bandwidth for network and 64 Gbps for storage is possible. It is clear how much this work will reduce cabling etc. and subsequently various costs.
In general, it can be said that this technology, with the platform it creates based on the x86 architecture for the data center, increases the scalability and makes it possible to implement resources and manage them as a single device. Using this technology, virtual machines can be transferred from one physical server to another physical server, and applications can easily move between virtual machines.
Cisco UCS is able to support VMware and other virtualization platforms and has the ability to support different operating systems. This technology is compatible with different systems and existing infrastructures. Therefore, by integrating computing and storage resources, UCS increases efficiency and simplifies information management.

Cisco UCS Physical Architecture
Cisco’s first servers were Mainframe. These servers had a high computing capacity and therefore had high installation and maintenance costs and also took up a lot of space. Today, these servers are used in military facilities, and organizations and companies rarely use this type of servers. With the advancement of technology, Personal or Rack mount servers came into being. The idea of these servers is one to one Server to Application.
In other words, each application came up on a separate server. Therefore, these servers have lower processing capacity than mainframe servers, but placing only one application on the server wastes the resources of a server.
A feature that was able to overcome these limitations was the Virtualization feature. Using the Virtualization feature, we can place more than one application on these servers. One of the problems with these servers is that they require cabling, power, and a separate cooling system to run a server. In the image below you can see examples of Cisco Rack mount servers.
Finally, Cisco Blade servers entered the market. One of the differences between Blade servers and Rack mount servers is that they include a single chassis that includes multiple servers. The advantages of these servers are less space occupied and less cabling required.
That is, different servers are placed separately from each other using a blade structure, and they can be easily connected or separated. In this architecture, a shared power is used for all servers and the management of these servers is central management. This server includes a cooling system for all the servers in a chassis.
The smallest servers are Rack mount servers that occupy 1RU (Rack Unit) in size. The height they occupy is 1.75 inches or about 2.5 cm. While Blade servers take up as much space as 6RU, the user can place up to 8 different servers. In terms of the space used, Blade servers are in a better position than Rack mount servers.
Cisco UCS Features
Cisco UCS servers have the following features:
UCS Stateless Computing
One of the most important features of Cisco UCS servers is Stateless Computing. This means that Cisco UCS servers are Bare Metal and do not include Logical Configuration. In other words, they do not include WWN or MAC addresses or BIOS settings or RAID settings.
Other brands of servers have logical settings as well as physical settings. This means that if your server has a network card, it has a Mac Address with it, or if it contains a FC card, it also includes a WWN address, or your server can have BIOS settings.
Other companies may configure RAID on the server via the RAID Controller. However, Cisco servers do not contain any logical settings and all settings must be done on a separate component called Service Profile. You can easily define a network card in the Service Profile section and assign it a Mac Address.
You can also define a SAN network card and assign it a WWN address. The user can boot or RAID settings in a Service Profile. After defining the Service Profile, it can apply the Service Profile to the Bare Metal server. The server can then be used on SANs. If there is a problem with your server and you need to change your server altogether, just apply the Service Profile to the new server.
Rapid Provisioning of UCS Server
This feature is another feature of Cisco UCS servers. Using this feature, you can create a Service Profile. You can apply this service profile to multiple servers at the same time.
Simplified Cisco UCS Troubleshooting
If you have a problem with one of your Cisco UCS License servers, you can easily switch the server and apply the Service Profile to it.
Cisco UCS Virtualization Capability
Cisco UCS servers are compatible with virtual environments such as VMware or Hyper-V or Citrix.
You can use the unique features of this brand by purchasing Cisco brand servers and preparing and ordering Cisco licenses that can be provided by this company.
Cisco UCS Models and Server Types
Cisco provides users with two types of UCS servers. The first type are Rack mount servers whose model code starts with the letter C and the second type are Blade servers whose model code starts with the letter B. These letters are followed by either the number 2 or the number 4, which indicates the number of CPU sockets.
There is also the letter M3 or the letter M4 in the Cisco server model. DDR3 RAMs are used in the servers whose model code has the letter M3, and DDR4 RAMs are used in the servers whose model code has the letter M4, and also the storage of these servers has increased compared to the other model.
The main difference between M3 and M4 servers is the type of CPU, RAM and storage. If we want to compare the 200 and 400 series servers, we must refer to the CPU, RAM and storage, and the number of network cards and the type of RAID that are supported on these servers.
