# Dedicated server configurations

A configuration is a description of a server's technical specifications (CPU model, RAM capacity, quantity, capacity and type of storage, and number and type of network interfaces).

Dedicated servers come in two configuration types:

* [prebuilt configuration servers](#prebuilt-servers),
* [custom configuration servers](#custom-servers).

For custom configuration servers, you can add graphics processing units (GPUs).

For projects with lower availability requirements, you can choose a Chipcore Line prebuilt configuration server or build a custom configuration Chipcore Line server.

You can check the availability of configuration types in locations in the [Dedicated Server Availability in Locations](/dedicated/about/dedicated-servers-availability-by-location.mdx) guide.

## Prebuilt configuration servers \{#prebuilt-servers}

Assembled and racked in advance, ready for use within two minutes after [ordering](/dedicated/order/order-prebuilt-server.mdx) (excluding OS installation time). Prebuilt configuration servers are divided into [lines](#lines) that differ in technical specifications.

After ordering a server, you can [perform an upgrade](/dedicated/order/change-server-configuration.mdx#prebuilt-server-upgrade).

### Lines \{#lines}

* Chipcore Line — affordable entry-level servers used for projects with lower availability requirements; they may be provided without a local network connection or KVM console access. You can view detailed configuration information in the [configurator](https://selectel.ru/services/dedicated/) when ordering a server. To access the KVM console, order the  [IP-KVM connection for 3 hours](/dedicated/about/additional-services.mdx#additional-services-with-one-time-payment);
* Entry Line — entry-level configurations for small projects, startups, and small businesses;
* Advanced Entry Line — an expanded number of server configurations for small projects, startups, and small businesses;
* Business Line — high-performance servers for medium-sized businesses and minor projects in the corporate segment;
* AMD Line — powerful AMD-based servers for hosting high-load services or applications;
* ARM Line — servers based on ARM architecture processors. An alternative to x86 architecture servers. Highly suitable for multi-threading and database workloads;
* Performance Line — high-performance servers for building virtualization clusters, complex systems, and infrastructure projects; servers with a high-speed network (10GE [MC-LAG](/dedicated/networks/mc-lag.mdx));
* Graphic Line — servers with graphics accelerators for GPU computing and graphical tasks;
* Storage Line — servers for storing large volumes of data;
* Discount Line — discounted servers at an attractive price from legacy lines.

## Custom configuration servers \{#custom-servers}

Assembled to order in our own production facility and ready for use in one to five business days. [Components are selected in the configurator](/dedicated/order/select-components.mdx) when [ordering a server](/dedicated/order/order-custom-server.mdx).

The configurator allows you to select only compatible components. During the assembly process, each server undergoes stability tests. This helps identify potential issues before the server is delivered.  Read more in the Selectel blog article [How we assemble custom servers: from configurator to testing](https://selectel.ru/blog/custom/).

After ordering a server, you can [change the server configuration](/dedicated/order/change-server-configuration.mdx).
