Hello! Here is a new article from the series “servers for the task”, in which I will tell you in detail how to choose a file server
From this article you will learn: why is itneedneeded, the principle of its operation, and at the end - specific recommendations for the selection of components. Well, according to the classics: brew a liter or two of coffee, tea or something stronger - and let's get started.
Mini-educational program
If you are an experienced system administrator (well, you never know) and don't want to refresh your memory, then feel free to skip this paragraph. There will be a short but very important educational program here - simple and clear. With it, we will tune in to the same wave, and you will close the gaps in the server topic. There is no need to cram anything, we are not in an IT class
What is a server?
A server (physical server, hardware wordpress web design agency server) is a professional computer that serves other computers and/or users (from several to tens/hundreds/thousands). The main task of the server is the effective execution of professional business services that are important:
Security, node redundancy, reliability and continuity of operation: since servers operate for months/years without interruption, it is necessary that the failure of an individual component or its maintenance/replacement does not put the server on pause. For this purpose, use:
Several power supply units (PSU): took out the old one, replaced it with a new one - the server did not stop working;
RAID arrays (Redundant Array of Independent Disks): several physical drives combined into one logical array, more about redundant disks in RAID will be below;
Server clusters: for example, two identical servers, one of which is always on standby - ready to take on the entire load;
Several different power sources: for example, one power supply is connected to the regular network, another to the backup with uninterruptible power supplies (UPS), and the third to the diesel generator if the UPS runs out of power faster than the main network is restored. There are also other power backup schemes.
Large amount of computing resources and scalability: one server slightly larger than a PC can accommodate 100+ cores, terabytes of random access memory (RAM), 4 power supplies, several network cards, etc. Advanced models support 2 and 4 processors (CPU, CPU) at once, many PCIe expansion lines (and therefore slots and boards), and dozens of RAM slots. A classic PC needs none of this, and therefore lags behind: only one processor, 2-4 RAM slots, and a couple of PCIe slots;
Remote management: IPMI technology provides full remote access to the server from anywhere in the world. You can manage it as if the server was right in front of you;
Automation: the system administrator often configures the server to operate in such a way that it can be forgotten for as long as possible. Servers (if configured this way) update themselves, send logs and other information to the administrator for verification, reboot, start and turn off the necessary software, repel DDoS attacks, make backup copies, and much more.
