Our Nine Infrastructure

Two separate data centers, a multiple redundancy network and high-quality server components form the technological backbone of Nine.

State-of-the-art data centers

Our Swiss data centers

Nine runs its data centers at two separate sites in Zurich (Switzerland). The productive servers and data backups are distributed across two sites.
Both data centres are connected by a route-redundant dark fibre ring. Thanks to this connection, the data can be exchanged redundantly between the individual data centres at 2x 10 Gbps. High availability is also ensured by the ring connection: if part of the ring is disrupted, the remaining parts take over data transfer automatically.
Backups are stored at one of both sites in a separate location isolated from the other systems.
Depending which site you choose, access is granted via biometric fingerprint scanner or the 24/7 on-site staff.
Nine ISO 27001 & FINMA Guidelines


With the option Cert+, we run your server in an ISO 27001 certified data centre under the guidelines of FINMA circular 2008/7 "Outsourcing - banks".

Green It

Nine State of the Art Infrastructure

Cooling is one of the most important components of a data centre. The type of cooling system used not only has a significant impact on overall energy consumption, but on the potential energy density and therefore degree of utilisation of the data centre.

Modern data centres are designed with a cold aisle arrangement, rather than cooling the entire data centre space. At Nine, our cold aisle design ensures that energy is used efficiently, while also making an important contribution to green IT.

In cold aisle cooling, the cool air is routed over the raised floor to the front of the racks, which face one another. This aisle is sealed by doors and a roof. The server systems suction the cool air and emit it as heated air into the space outside the cold aisle. This space is known as the hot aisle. The emission of heated air causes the ambient temperature in the hot aisle to increase significantly, and particularly at the back of the racks temperatures can reach well over 30°C. However, by using rack-optimised equipment and a constant, regulated temperature in the cold aisle, the raised temperatures do not present any problems.

In the cold aisle itself, a consistently low air temperature is maintained regardless of the location of the server system within a rack. The high temperature level between the cold and hot aisle allows the air conditioning to work more efficiently, which in turn allows longer use of free cooling without cooling systems, even with relatively high outside temperatures of up to 15°C.

An important aspect of the overall cold/hot aisle concept is the use of rack-optimised equipment. The cold air must be suctioned correctly at the front. The racks must also be properly sealed with panels to ensure that no hot air can get into the cold aisle. It is therefore essential that unused rack units are completely sealed. In order to be able to ensure this, and therefore contribute effectively to green IT practices, Nine conducts weekly inspections in the data centre.

As a further contribution to green IT, Nine only uses power generated from renewable energy sources. Our travel is also completely climate-neutral thanks to our collaboration with myclimate (certificate 2021). Customers of Nine who want to run their server product in an eco-friendly way can add the CO2-neutral operation and/or eco-power options to their product simply by sending us an email.

our strengths

Nine has two separate locations in Zurich. The production servers and backups are split between two locations. Both data centres are connected to one another using a redundant dark fibre ring. This connection allows for the redundant exchange of data between the two data centres at a speed of 2 x 10 Gbps. In addition, the ring connection ensures the high availability: If part of the ring is disrupted, the remaining parts take over the data transfer automatically.

Energy efficiency

Cooling is one of the most important components of a data centre.  The cooling system type and method are not only responsible for a substantial portion of the power usage, but also define the potential performance density and thus a data centre’s load intensity. Modern data centres use a principle called cold aisle containment, instead of cooling the entire area of the data centre itself.
At Nine, we use this cold aisle design for efficient energy use and are thus making an important contribution to a green IT.

As a further commitment to a green IT, Nine receives its electricity exclusively from renewable energy sources, and with the support of myclimate (certification 2021), we are completely carbon-neutral. Nine customers who would like to run their server product in an eco-friendly manner can easily add the option ‘carbon-neutrality’ to their product via e-mail.
