Concepts
Enterprise Bare Metal (EBM) provides dedicated physical servers with complete resource isolation and no shared hardware components. This page outlines the core concepts of the EBM infrastructure, including server chassis specifications, provisioning timelines, and the scope of included services.
Dell server chassis
Dell PowerEdge servers form the backbone of our infrastructure, providing robust solutions for a wide range of computing needs. Our experience has proved the reliability, performance, resilience, and low maintenance requirements of Dell servers. The majority of our servers are rack-mountable, standing either 1U or 2U high.
To distinguish between the server model and chassis model, we adhere to the following terminology:
- A chassis model is a server's body with the key components such as processors installed and the backplane, excluding attachments such as disks, RAM, and so on. The processor installed in the chassis does not change. Each chassis can accommodate several server models.
- A server model represents a real server with all attachments (disks, RAM, additional network cards and so on).
We offer chassis with a wide range of system classes, processors, and platform generations, enabling the creation of solutions for small businesses and providing scalability for large enterprise tasks. The naming generally consists of a letter(s) followed by three numbers (e.g., PowerEdge R240):
A brief description of the available server chassis:
| Model | Description |
|---|---|
| R2xx | A single-socket (single CPU), single PSU system in the 1U size. They are installed into server racks equipped with Automatic Transfer Switches (ATS). See the Power redundancy section of this article. R2xx servers usually do not have a RAID controller installed. The second network interface controller occupies the only PCI expansion slot. See the Network redundancy section of this article. |
| R3xx | Practically the same as R2xx, but it has two power supply units (PSUs). |
| R4xx | Dual-socket 1U system. Two CPUs allows for more RAM, more PCI lanes, and so on. |
| R5xx | 2U dual-socket system. Has more storage slots, expansion slots, and PCI lanes than R4xx. |
| R7xx | 2U dual-socket system for storage and data processing workloads. Up to 26 x 2.5" drives per server. |
| T6xx | They are explicitly used for GPU servers. Despite being the "tower" type, the chassis can be installed into a server rack as a 5U unit. |
Dell servers come with an autonomous subsystem for management and monitoring capabilities – iDRAC. It is a hardware component installed on the server's motherboard and allows for server management even when the server is turned off. iDRAC provides both web and command-line interfaces.
Provisioning time
Provisioning time is the duration required to configure and provide the dedicated server in the requested configuration after it has been ordered. Provisioning ETA:
- From 15 minutes – The ordered server configuration is available in the rack
- 24 hours or more – The ordered server is not currently in the rack or configuration changes are needed
If server hardware needs to be ordered or transported, the server provisioning time is determined by the delivery deadlines. For additional information on the server provisioning stages, refer to server provisioning.
Included services

Additional services
A list of additional services that can be applied to the ordered dedicated server:
- HDD upgrades
- RAM upgrades
- Paid operating systems
- Extended traffic packages

- Uplink aggregation
We offer the possibility to discuss and fulfill custom requests for hardware and networks. These services are provided only after approval from our managers and architects.
Dedicated server ID
Each ordered dedicated server is assigned a unique identifier. This ID is used to identify the server in Servers.com Public API requests and for accessing technical support. Refer to the API documentation to find out the capabilities and available operations for dedicated servers.
