Frequently Asked Questions

General Questions

What is Colocation?

Colocation is a service where you place your own server equipment in a professional data center. You own the hardware, while we provide the physical infrastructure — space, power, cooling, network connectivity, and security. For more information, see Introduction to the service.

Where is the data center located?

The data center is located in Sofia, at the Equinix facility — one of the largest international data center operators. The site is certified as Tier 3+ with ISO 9001:2015, ISO 27001:2013, and ISO 50001 certifications.

Ordering and Activation

How can I order the service?

The Colocation service cannot be ordered directly from the client area. Send an inquiry to sales@delta.bg or create a ticket from the client area. Our team will review your request and prepare an individual quote. For details, see How to Order.

What information is required for the quote?

To prepare an accurate quote, we need:

  • Number and size of machines (in U)
  • Approximate power consumption (in W)
  • Number and speed of network interfaces
  • Remote access requirements (IPMI, pre-installed OS)
  • Planned start date

For details, see Required Information for the Quote.

How long does preparation take?

Once we receive your equipment, installation in the data center is performed within 2 business days. Prior to that:

  • Quote preparation and approval — usually 1-3 business days
  • Contract signing
  • Shipment of equipment to our office

The total time from inquiry to activation depends mostly on your hardware shipping time.

How is the price calculated?

Pricing depends on:

  • Space occupied (U count or full rack)
  • Power consumption
  • Number and speed of network interfaces
  • Additional services (24/7 support, monitoring, etc.)

Every quote is individual and tailored to your specific needs.

Hardware Requirements

What servers can be colocated?

We colocate only machines designed for mounting in a standard 19-inch rack. Desktop (tower) servers and workstations without a rack mount kit cannot be colocated. For details, see Hardware Requirements.

Do I need to send rails?

Yes. Every server requires vendor-provided rails compatible with the specific model. Without rails, the machine cannot be mounted stably in the rack. Check the server specification for required rails and make sure you have them.

What power cables are required?

Rack outlets use C13 connectors. Most server power cables have C14 → C13 connectors and are compatible. Verify you have such cables before shipping.

What is the maximum power consumption limit?

Standard racks support up to 4-6 kW, while high-power racks — up to 12 kW. The specific limit is agreed in the quote based on your machines.

Can I colocate a machine with two power supplies (dual PSU)?

Yes. If the machine has two power supply units, you can connect it to two independent power lines (A and B). This provides redundancy — if one line fails, the machine continues operating. We recommend this configuration for critical infrastructure.

Remote Access and Management

How do I get remote access to the machine?

Two main methods are available:

  1. Pre-installed OS — before shipment you install an operating system and configure access (SSH, RDP)
  2. IPMI over OpenVPN — if the hardware supports IPMI, we provide remote access to it over OpenVPN

For details, see Remote Access.

What is IPMI and why do I need it?

IPMI (Intelligent Platform Management Interface) is a standardized interface for remote server management at a level below the OS. It allows power on/off, rebooting, hardware monitoring, and a remote KVM console. Without IPMI, if the OS fails to boot, the machine cannot be managed remotely.

Can I visit the data center?

Yes, after prior scheduling and access profiling. Self-access without prior approval is not possible due to strict security policies. For access, contact our team.

Do you offer Remote Hands services?

Yes. For cases requiring physical intervention (disk swap, installing a component, power button reboot), you can request a technical service from our team. This is especially useful for customers who cannot visit the data center physically.

Networking and Connectivity

What network speeds are offered?

Available speeds are 100 Mbps, 1 Gbps, and 10 Gbps per port. For non-standard speeds (25G, 40G, InfiniBand), consult our team.

Is network traffic billed?

Traffic and exact parameters are defined in the quote and depend on the chosen plan. For detailed information, contact our Sales department.

Do you offer public IP addresses?

Yes. The required number of public IP addresses is specified when preparing the quote. If you need a large IPv4 block or IPv6, this can also be agreed upon.

Can I connect my own ASN or run BGP?

For individual requirements such as BGP peering, announcing your own IP blocks, or connectivity via your own ASN — contact our team to discuss technical implementation.

Support and Security

What is the level of physical security?

The data center has multi-zone access control with biometric systems, 24/7 video surveillance, armed 24/7 security, and visitor profiling. Only authorized personnel have access to the racks.

Is there backup power?

Yes. The data center has four independent power sources, backed up by UPS and five diesel generators — providing unlimited autonomous operation time during power outages.

What happens in case of fire?

The data center has a multi-zone fire detection system with a dual-trigger mechanism — thermal and smoke sensors. When an issue is detected, automated suppression systems activate, the zone is isolated, and security is notified.

Can I add 24/7 support?

Yes. With the Colocation service, you can add 24/7 management and administration from our system administrators and DevOps engineers. This is especially useful if you don't have your own technical team. Specify during quote preparation.

What happens to data in case of hardware failure?

Responsibility for data on the colocated machine is entirely on the customer. We recommend regular backups — you can use the Delta Cloud Backup service for a professional solution with automated archiving.
