El servidor dedicado suele ser el más alto en la escala de servicios de alojamiento. Es una máquina física completa que está destinada a personas que saben lo que quieren y proyectos que son demasiado grandes para otros servicios de alojamiento.

Pero, ¿cómo funciona en la práctica el alojamiento dedicado? ¿Cómo elegir un servidor de este tipo y a qué prestar especial atención? ¡Controlar!

¿Qué es un servidor dedicado y cómo funciona?

Servidor dedicado  : una computadora independiente que funciona continuamente ubicada en la sala del servidor (centro de datos), conectada a Internet, que las empresas de hospedaje ofrecen como servicio de alquiler.

El servidor dedicado tiene un sistema operativo instalado y se accede a través del protocolo SSH (Linux) o escritorio remoto (Windows Server).

Los servidores dedicados se utilizan principalmente para servicios tales como: alojamiento de sitios web, correo electrónico, bases de datos, cuentas FTP, almacenamiento de archivos, copias de seguridad u otras aplicaciones, software y servicios de Internet.

Como parte del servicio de alquiler, la empresa de alojamiento proporciona el equipo (servidor físico), que se coloca en el centro de datos (la mayoría de las veces en un rack) y garantiza su funcionamiento las 24 horas y sin fallas. El arrendatario de un servidor dedicado es responsable de su seguridad o del lanzamiento y configuración de servicios (software) sobre el mismo a su discreción.

Servidor dedicado versus hosting compartido y VPS

En el caso de un servidor dedicado, alquilamos la máquina física completa. No se trata de virtualización (como en el caso de los servidores VPS) o de configuraciones de servicios de servidor listas para usar (como en el caso del alojamiento compartido).

Below is a table showing the most important differences between a dedicated server and shared and VPS hosting:

Independent system selection and configuration Not Yes Yes
Possibility to install custom software Limited Yes Yes
Administrative knowledge required Not Yes Yes
Resource Guarantee Not Yes Yes
Ability to scale resources Yes Usually yes Usually not

Detailed differences can be found in the guide: What is hosting and server?

Who is the dedicated server for? It is a solution designed for people who require full freedom of operation (greater than on VPS servers) and need much more resources than standard hosting services offer.

How to choose a dedicated server?

Below is a list of 8 aspects that are worth paying attention to when choosing a dedicated server.

1. Processor (CPU) and memory (RAM)

The basis and heart of every computer’s operation (and a dedicated server is ultimately a computer) is the processor and memory.

When choosing a dedicated server, you should choose them depending on your needs and requirements. This is one of the first things you need to pay attention to when choosing a dedicator.

I am not able to offer any reasonable minimum, because everything (cores, threads, processor clocking, memory type and capacity) depends on the needs and services that will be run on the server, as well as traffic and load. However, I recommend that the offered components (CPU and RAM) are of server / enterprise class (e.g. server RAM ECC, Intel Xeon or AMD EPYC line processors).

The difference between home and server equipment is that the latter are designed for continuous operation under high loads and with much higher reliability / performance.

Some smaller hosting companies sell dedicated servers based on consumer equipment, but despite the obvious lower price, it is worth avoiding such offers if you are looking for a server for professional use.

2. Hard drives

The same principle as in the point above applies to hard drives. Disk manufacturers offer series of equipment designed for home and server applications. It is worth making sure that in the rented dedicated server there will be disks intended for this .

When it comes to the types of discs, we can choose from:

  • HDD – free disk drives
  • SSD – fast SSD / semiconductor drives. Much more efficient than HDD
  • SSD NVMe – the fastest solid state drives. Up to 10-11x faster than the previously mentioned SSDs

For obvious reasons, I recommend primarily servers based on the latter. Alternatively, if we want to store more data on the server (and when the cost is important), you can opt for a machine with 4 disks (2 smaller and faster NVMe SSDs, e.g. for databases, system and frequent operations + 2 larger SSD / HDD for storage unchanging data, e.g. images, video, audio, etc.).

And it is not without reason that I am always writing about two disks. In the case of dedicated servers, we have to take care of the appropriate RAID configuration ourselves , ensuring, among others, uninterrupted operation in the event of failure of one of the disks. The minimum is RAID 1 , ie two identical disks acting as their “mirrored”. When we have a larger budget, we can also be interested in RAID 10 (RAID 1 + 0), e.g. a 4-disk configuration, which, in addition to good security, will increase the speed of the array.


3. Link

Companies that offer dedicated hosting usually include information about the Internet connection running on the server. The link bandwidth is given as a parameter (e.g. 250 Mb / s).

It is worth remembering that in the case of server services, these are symmetrical links – it means that the example 250 Mbps should be available both as download and upload.

In the case of a dedicated server, a good minimum will be 100-250 Mb / s of bandwidth. However, if high traffic is expected, consider a 1 Gb / s connection.

4. SLA

SLA is a guarantee of failure-free operation of the service expressed as a percentage. In the case of dedicated SLA servers, e.g. 99.90%, it means that the server’s failure due to hosting (problem with power supply, internet connection, server component) will not exceed 0.01% of the time per month or year.

Therefore, it is worth choosing an offer that offers the highest possible SLA . Preferably above 99.95% (i.e. a maximum of 21.56 minutes per month / 4.38 hours per year).

What if the SLA is exceeded by the hosting company? Details are usually included in the service regulations (worth reading!) Or in a separate SLA agreement or service availability guarantee.

5. Additional IP addresses

Each server sold by hosting companies has a dedicated IP address. Often, however, we will need more than one address (eg whole class / subnet). It is worth checking in advance what is the cost of purchasing an additional IPv4 address .

Typically, an additional IP address is charged monthly. Some companies also charge a fee for just starting a block of IP addresses (activation fee).

An interesting solution is also the so-called failover IP – is an additional IP address that can be assigned to various dedicated servers or VPS and switched seamlessly between them.

6. Management panel

In addition to the customer panel (used to pay for the service, data changes, etc.), hosting companies also provide a separate panel (or section in an existing panel) to manage the purchased dedicated server.

A good dedicated server management panel should have functions that enable:

  • selection of operating systems when installing from a wide range
  • installing the operating system from your own ISO image
  • start, stop, restart the server
  • checking the history and current consumption of server resources (processor, memory, HDD / SSD, transfer)
  • access via VNC (console from the panel level)
  • adding / removing / changing SSH keys
  • change / set Reverse DNS (revDNS)
  • protection of access to the panel with 2FA

It is worth asking the hosting about it or running a DEMO of the panel, if available, to see if all the necessary functions are available there.

7. Technical assistance

Regardless of how functional the hosting panel will be, sometimes there are issues that cannot be clicked on. It is then necessary to have an account with the customer service office.

When choosing a dedicated server, I recommend checking what are the methods of contacting the support, what is the response time to a failure and what the customer service and technical support looks like .

In the case of good dedicated servers, technical support is rarely used, but it is worth making sure before buying whether you can, for example, call or write to the hosting with a failure report in the middle of the night or at the weekend.

8. Data center and location

The last thing to verify is the server room itself, in which the dedicated server and its infrastructure will be located.

It is worth paying attention to this:

  • are the servers protected with an anti-DDoS service – attacks sometimes happen. The question is whether the hosting will try to protect us against them, or rather terminate the contract
  • what redundancy looks like – breakdowns or service work is a normal thing. A good data center should use backup components both on the servers themselves (e.g. two power supplies) and on the services (e.g. independent power lines, independent internet connections)

Classifications and standards such as TIER (preferably at least TIER III) or certificates such as the European ‌ISO / IEC TS 22237 (previously: EN 50600) or the American ANSI / TIA-942 may be useful .

The very location of the server is also important. The closer to the target clients of the services running on the server, the lower the ping and, consequently, the faster the performance . The location of the server outside the European Union for EU customers may also be important in terms of GDPR. You can read more about the hosting location in the guide: Hosting  abroad? 6 things you need to consider

Before buying, it is worth finding out where our server will be physically located (in which data center) and check how a given server room is technically (security, services) compared to the competition.

Un servidor dedicado es un servicio avanzado para clientes exigentes. Además, muchas veces no es el más barato. Vale la pena analizar cuidadosamente las ofertas y verificar las opciones disponibles para elegir una solución segura y estable que se ajuste a los requisitos del proyecto. Espero que con esta guía haya podido acercarte a tomar la mejor decisión posible. Buena suerte 🙂
