Server colocation

Colocation means placing hardware you own — servers, storage arrays, switches, firewalls — in a professional data center. The data center provides the rack space, power, cooling, connectivity and physical security; you keep full ownership and control of the equipment and everything running on it.

It is the middle ground between running your own server room and renting servers: you avoid the cost of building and maintaining a server room, without giving up your own hardware.

A 19-inch rack is the industry-standard cabinet for IT equipment. The name comes from the width of the mounting rails: 19 inches (482.6 mm) between the outer edges of the front panels, as defined by the EIA-310 standard. Servers, switches and storage from every major vendor are built to fit it.

The most common full-height rack has 42 rack units (42U) of usable space — about 1.87 m of equipment.

U (rack unit) is the unit of height in a rack: 1U = 1.75 inch = 44.45 mm. A "1U server" is a flat server that takes one unit; a 2U server takes two, and so on. A 42U rack therefore holds, for example, 42 servers of 1U or 21 servers of 2U.

In our pricing you pay for the number of units your equipment occupies — PLN 79.00 net per 1U per month.

A dual power feed means that a device is connected to two independent power paths — usually called feed A and feed B — each with its own distribution unit (PDU) and, further upstream, its own UPS. If one path fails or is taken down for maintenance, the device keeps running on the other one.

To benefit from it, the device needs two power supplies (redundant PSUs), which most enterprise servers and switches have. Devices with a single power supply can be connected through an automatic transfer switch (ATS). Tell us in your quote request if you need A+B power.

Tier is a data center classification by the Uptime Institute, from Tier I (basic) to Tier IV (fault tolerant). A Tier III facility is concurrently maintainable: it has redundant components and more than one power and cooling distribution path, so any part of the infrastructure can be serviced or replaced without shutting down the IT equipment.

The design availability of Tier III is 99.982%, which corresponds to about 1.6 hours of potential downtime per year. Our colocation facilities are Tier III and ISO 27001 certified.

Tier III is concurrently maintainable: planned maintenance does not interrupt operations, but a single unexpected failure in some parts of the infrastructure may still affect it. Tier IV is fault tolerant: every critical system is fully duplicated (typically 2N or 2N+1) in physically separated, simultaneously active paths, so even an unplanned failure of any single component does not stop the IT equipment.

Tier IV design availability is 99.995%, about 26 minutes a year. It is also much more expensive to build and run, which is reflected in the price. For most business systems, Tier III combined with redundancy on your side — dual-powered servers, or equipment in two of our locations — gives very high availability at a far lower cost.

PUE (Power Usage Effectiveness) is the ratio of the total energy a data center uses to the energy consumed by the IT equipment itself. The difference is mainly cooling and power conversion losses. A PUE of 1.5, for example, means that for every 1 kWh your server uses, the facility uses 1.5 kWh in total.

Our energy rate of PLN 1.30 net per kWh already includes PUE, so you are billed only for what your devices draw — no separate cooling fees.

It is the sum of four components: rack space (PLN 79.00 per 1U), energy (PLN 1.30 per kWh of actual consumption, PUE included), internet (PLN 1.00 per Mb/s of the speed you choose) and IP addresses (PLN 12.00 per IPv4 address). For example, a 1U server drawing 0.2 kW with a 100 Mb/s connection and one IP address costs about PLN 378.20 net per month. Use the calculator above for your own setup.

A symmetric (1/1) connection with no transfer limits, from 100 Mb/s up to 5 Gb/s. You pay PLN 1.00 net per Mb/s per month for the speed you choose, regardless of how much data you transfer. Public IPv4 addresses cost PLN 12.00 net each per month.

Yes. We offer turnkey colocation: we collect your equipment with secure, dedicated transport directly from your company, install it in the rack and connect it. On request we can also plan the migration so that the downtime of your services is as short as possible.

Yes. We have data centers in Warsaw, Kraków, Katowice, Opole and Lublin. Spreading equipment across two locations protects your services even against the loss of an entire facility — a common requirement under NIS2 and DORA.
