What is a SERVER?
A server serves as a forum for multiple users to exchange data (files/images) and applications (email, for example). Many of the same components are used in a server as in a standard PC, but they are typically of higher quality, designed and constructed for continuous rather than intermittent use.
Why do we need a SERVER?
Data and information can be easily exchanged between colleagues using a server. This is particularly useful if you have several teams working on a project or if you have remote or mobile staff that need access to work files.
One of the most significant advantages of having a server is that data is safely stored, and network access can be tightly regulated through centralised authentication.
- Data back-up and recovery
It’s easy to set up a data backup and recovery system so that any files that are accidentally lost or destroyed can be quickly retrieved. A crashed hard drive in a server, unlike single computers, is not a tragedy that will disrupt your company. Instead, it’s a simple event to handle.
- Remote Management
As previously stated, a best vps server can be used to handle almost every aspect of a company. The ability to monitor and maintain the server remotely adds another layer of convenience. Problems with the server or network may then be diagnosed and repaired remotely, as well as routine maintenance and upgrades.
Anti-virus software and firewalls can be controlled on a server, protecting all data, and security breaches are much less likely with the ability to monitor network access through passwords and user names.
- Dedicated Servers
Print, email, web, and file servers are the most popular types of dedicated servers. Using a linux dedicated server for a specific purpose enables resources to be guided to where they are most required and simplifies server management.
- Home Servers
Home servers, such as those from HP, are now very cheap, and an old PC can be easily converted into a server for a low price. A home server can be used to connect all of the computers and peripherals in the building, as well as to handle home automation, CCTV, and even a home media centre.
Form Factors :
You can choose from three different type factors: tower, rack, or blade. The one you pick will be decided by a variety of variables.
Server Virtualisation : This is simply a method of running multiple ‘virtual’ servers on a single ‘physical’ server by using features in the server software.
To allow the most effective use of the server, the processors, hard drives, and components inside the physical box are intelligently spread out between the virtual servers.
- Tower : Tower servers are self-contained, stand-alone servers that are suitable for small businesses. They are the size of a standard desktop computer and can be placed underneath or on top of a desk to provide a full all-in-one solution. A rack server is often chosen when more processing power is needed.
- Rack : These servers are usually located in racks inside a small cabinet or in a dedicated data space, as the name implies. Rack servers, which have built-in expansion slots and can be used for virtualisation platforms or linked to NAS or SAN external storage systems, are more modular than tower versions.
- Blade : Blade servers are the smallest of all server types, taking up less room than even rack models, allowing for more servers to be crammed into the same space. These servers are ideal for companies that process a lot of data because they store data on blades but can also bind to external storage like NAS. All can be handled from a single location since components can be shared between servers.
Server Specification : A server has the same basic components and configuration as a desktop PC, but its specifications are usually much higher.
A single server, for example, can often house several multi-core processors. The processor, also known as the CPU, should have the highest possible specifications.
Server Memory : As a server’s processing capacity grows, more memory is needed to sustain the increased workload. To support two or more processors, servers with two or more processors may need additional memory.
