This article is dedicated to choosing a server for the office. You can buy a ready-made or configure an office server in our catalog.

This article is intended for people who have decided to understand, with zero background in IT, the criteria by which servers are selected for the office, and what related issues are solved by system administrators. This knowledge is not enough to independently build an IT infrastructure, but you will be able to explain to a specialist in general concepts what result you want to achieve. And he will choose the optimal method of technical implementation.
So that you understand how much variability there wordpress web design agency is in choosing servers. And this is a small part of the parameters without internal components and software. If you dig deeper, there are dozens of times more nuances.
Server tasks Brands Form factors Dimensions
A server in the office is needed so that programs work around the clock and without human intervention. An office server allows you to solve problems that a PC cannot handle, and also makes software work faster and with fewer problems. This is achieved by excess computing resources, special server software and reliable hardware.
The very concept of server comes from the English word to serve . Therefore, a server is literally a “servicer”, a computer created to simultaneously support a large number of users and run specialized software. The so-called hardware-software complex (software server + hardware server).
How does a server work in an office?
The BelAZ-75710 costs around $6,000,000, but pays for itself over time as it reduces transportation costs.
Servers often operate automatically. System administrators configure the servers once, and then only optimize, update software, etc. And if a serious error occurs and the operating system stops responding, there is a special tool that allows you to manage servers from another point on the planet over the network (IPMI protocol), as if they were right in front of the administrator.
And servers have a lot of such features.
Imagine that you need to transport 50 kg of crushed stone from point A to point B. You arrive in your car, load a couple of bags into the trunk, and then easily and quickly complete the task. Now imagine that there are 4 tons of crushed stone. Even if you load 200 kg into the trunk, you will have to drive there and back 20 times. The same KamAZ will handle the task in 1 trip.
But what if you need to transport 400 tons of crushed stone? That's 2,000 trips by car and 100 trips by truck. Too much, isn't it? To complete this task, you need a hero and a professional approach - a two-axle BelAZ-75710 quarry dump truck. This monster is capable of transporting 450 tons of cargo in 1 trip. But not on regular roads. And it works the other way around - transporting 50 kg of crushed stone on trucks and dump trucks is uneconomical, it's better to take a small pickup.
Drawing an analogy with computers:
PC is a passenger car or a small pickup truck;
The server is a KamAZ or BelAZ.
If you calculate the efficiency per ruble spent, the server will win against the PC, but overall it is an expensive professional tool that effectively solves a huge range of business tasks. See " Server tasks ".
PowerEdge R750xa
Dell PowerEdge R750XA rack server. Price from $17,000 to ≈ $270,000 (1,190,000 and 18,900,000 rubles). Upper price segment model.
You can't install 4 power supplies with redundancy and hot swapping (without rebooting) in a regular PC or workstation, you can't install 24 hot swappable hard drives and combine them into a RAID array to increase read/write speed and disk subsystem reliability, you can't install RAM with error correction (ECC memory). And there are many other things you can't do. Yes, some models support certain functionality, but not everything at once.
A smart system administrator will not run critical business processes on a system that is unstable and lacks redundancy.
But servers are not a panacea either – their functionality is limited by vertical growth (you can’t fit 50 processors there). Therefore, if the nature and intensity of the loads increase, admins buy one or more servers. They are called nodes. Nodes can work as independent units or be combined into clusters:
Fault-tolerant – if one server fails, the load will “move” to another;
Productive – several servers work as a single system, they allocate all their resources for simultaneous processing of complex tasks;
With load balancing - one or more load balancers distribute(s) different requests between servers in the cluster to increase processing speed and/or increase the overall fault tolerance of the entire system.
