Hardware Requirements

Before shipping hardware for colocation, it's important to ensure it meets the data center's technical requirements. This guarantees correct installation and smooth operation.

Rack Compatibility

The data center uses standard 19-inch racks. The machine you want to colocate must be designed for mounting in such a rack.

Warning

Desktop (tower) servers, workstations, and equipment without a rack mount kit cannot be colocated. Even if you have physical space in the rack, machines without proper rack design have no stable mounting and disrupt cooling airflow.

Supported Sizes

  • 1U — standard form factor for small servers (e.g., Supermicro SuperServer 1U, Dell PowerEdge R1xx/R6xx, HP ProLiant DL3xx Gen 1U)
  • 2U — mid-capacity servers with more disk slots (e.g., Dell PowerEdge R7xx, HP ProLiant DL3xx Gen 2U)
  • 3U and 4U — servers with large storage subsystems or GPU machines
  • Larger configurations — when renting a half or full rack, you can combine machines of different sizes

Mounting Rails

Every server requires vendor-provided rails compatible with the specific model. Rails are installed in the rack and allow the machine to be placed stably and pulled out when servicing is needed.

Note

Check the server specification for the required rails and make sure you have them before shipping the hardware. Rails are usually sold as a separate accessory.

Rack Depth

Our racks have standard depth, compatible with most servers. If your machine has an unusually long or short depth, notify us during inquiry so we can verify correct installation.

Power

Connectors

The rack PDU outlets use C13 connectors. This is the standard connector for server equipment and is compatible with most server power cables (which have a C14 plug).

Tip

Make sure you have the necessary C14 → C13 power cables to connect the server to the PDU. Most servers ship with such cables, but always verify before shipping.

Power Consumption

Each rack has a power consumption limit agreed in the quote. Typical limits are:

  • Standard rack — up to 4-6 kW
  • High-power rack — up to 12 kW (suitable for dense configurations with GPU machines)

Before shipping the machine, verify the rated consumption (TDP) and ensure it fits within the agreed limit. If you plan to colocate multiple machines, sum their consumption.

Redundant Power

Machines with two power supply units (dual PSU) receive power from two independent power lines. This guarantees that if one line fails, the server continues to operate without interruption. We recommend this setup for critical infrastructure.

Network Interfaces

When ordering, specify how many network interfaces are needed and at what speed. Available options are:

  • 100 Mbps, 1 Gbps, or 10 Gbps per port

The rack connects to our infrastructure via standard UTP/STP cables (for 100 Mbps and 1 Gbps) or SFP+/SFP28 optical modules and cables (for 10 Gbps).

Note

If your machine has specific network cards (e.g., 25 Gbps, 40 Gbps, or InfiniBand), contact our team to evaluate integration with your configuration.

Labels and Documentation

Before shipping equipment:

  • Label each machine with a clear tag (e.g., with a name or asset number) to ease identification during installation
  • Include documentation — specification, configuration sheet, mounting instructions if needed
  • Include all accessories — power cables, rails, network modules, service documentation

Testing Before Shipment

We strongly recommend testing the machine before shipping:

  • Power it on for at least 24 hours and check for hardware errors
  • Update BIOS/firmware to the latest stable version
  • Configure IPMI (if the machine supports it) — record the IP address, username, and password
  • Install a base OS (optional) or leave the machine to be installed after mounting
