Select components for a dedicated server of arbitrary configuration
You can build and order a server of any configuration.
Depending on the components, server assembly takes from one to five working days.Read more about building servers of arbitrary configuration in the Selectel blog article How we build custom servers: from configurator to testing.
When the server is ready for delivery, you will receive an email notification and can connect to it.
If you need help selecting components, create a ticket or contact us in other ways.
Select accessories
When ordering a random server, you select components in the server configurator.Not all components are compatible with each other.When configuring the configuration after selecting each new component, incompatible components are automatically excluded.
Processor
Once the server is ordered, the processor cannot be replaced.If a different processor or a change in the number of processors is required, order a new server.
Intel and AMD processors are available for ordering.
In the configurator the processors are grouped by lines and families.The model, number of cores, base clock frequency and additional designations are indicated in the processor name.
Examples of processors:
- Intel Silver 4510 (12x2.4 GHz HT);
- AMD EPYC 7443P (24x2.85 GHz SMT).
Processors may have additional designations:
Memory
DDR4 and DDR5 generation modules are available for ordering.
In the configurator you can select:
- total memory capacity;
- or module size and number of modules. The configurator will automatically display the total ordered capacity. Use this option to select the number of modules by the number of processor memory channels.
The RAM name indicates the capacity, generation, and additional designations.
RAM example: 64 GB DDR4 ECC Reg.
RAM may have additional designations:
Disks
The disks are installed in the following order: NVMe ⟶ SSD ⟶ HDD. If you need a different installation order, please specify it in the comment at [checkout](order entry).
In the configurator disks are grouped by type. Disk names include capacity, disk type and additional designations.
Disk example: 500GB NVMe M.2 SSD.

HBAs and RAID controllers
RAID controllers are devices for organizing and managing disk arrays using RAID technology. RAID controllers manage RAID operations at the hardware level, relieving the system processor.
Disk controllers are needed when the number of disks exceeds the number of SATA ports on the motherboard and for additional data protection using hardware RAID. Read more in the Selectel blog article Hardware RAID: Features of Use.
Types of HBAs and RAID controllers
Network cards
Each randomly configured server is by default equipped with two RJ45 network interfaces with a data rate of 1 Gbps each.The first interface is used for Internet connectivity, the second for private networking — see the Dedicated Server Networking instructions for more details.
If more network interfaces are required or if you want to reserve the connection with MC-LAG, additional network cards can be ordered.
Types of NICs
GPU
GPU (Graphics Processing Unit) is a graphics processor designed for accelerated data processing. It is used for tasks:
- machine learning;
- data analytics;
- scientific computing;
- Virtual Desktop Deployment (VDI);
- video broadcasts;
- work with graphics, video rendering, etc.
Learn more about conditions and choosing a graphics card for specific tasks in Selectel's blog article Can desktop graphics cards compare to server graphics cards.
For servers with (GPU) graphics cards are available in PCI-e devices. Up to 8 graphics cards can be installed in one server.
In the configurator, the model, amount and type of video memory are specified in the name of the video card. Example GPU: RTX A5000 24 GB GDDR6.
PCI-e devices
A trusted boot tool is a certified hardware and software module that:
- helps prevent unauthorized access to the server during the operating system (OS) boot phase;
- monitors the integrity of the server hardware configuration and files before the OS is booted;
- blocks booting from removable media.
It is used to certify the system for security requirements or to fulfill the requirements for the operating environment of certified cryptographic information protection means with class KS3.
Example of a PCI-e device:
Motherboard
When ordering a server, the configurator displays motherboards that are compatible with the selected accessories. If only one motherboard is compatible, the field will be filled in automatically.
Case
When ordering a server, the configurator displays the available enclosure options that are compatible with the selected accessories. If only one variant is compatible, the field will be filled in automatically.
An enclosure with two or more power supplies is recommended to ensure uninterrupted server operation. If you may need to upgrade your server in the future, choose an enclosure with more free garbage cans.
Recommendations for selecting components for tasks
Game servers
For servers that synchronize gameplay, high CPU frequency and large amounts of RAM are important.
Servers with large databases
Large databases require a scalable, high-performance processor. A large number of active database operations requires more processor cores. Server performance is affected by RAM, as it is used to cache data, process queries and perform operations on them.
1C servers
1C:Enterprise and its databases are demanding on processor performance and actively use RAM for calculations and data caching. Many 1C operations are single-threaded, so their processing requires a processor with high frequency. In 1C operation, the speed of data access is important, especially with a large number of transactions and active read and write operations.
Servers for virtualization
Virtualization requires significant computational resources, especially when there is a high density of virtual machines (VMs) and heavy workloads.The more cores and threads a processor has, the more VMs can run on the server.If more cores are needed, you can build a server with two or more processors.
Each VM requires a portion of RAM to be allocated for its operation.The more VMs on the server, the more RAM is required.
Storage speed has a direct impact on VM performance.
Machine learning models
For servers designed for machine learning models, performance processors, graphics processors with large amounts of video memory, large amounts of RAM, and high-speed storage are important.
In machine learning, the GPU takes the brunt of the workload. The more parameters and the more complex the training model, the more memory the GPU will need to work efficiently. Read more in the Selectel blog article How to choose a graphics card for training neural networks and Deep Learning.
