Yet another private hall was established in our datovém centru DC TOWER Prague I in the Žižkov quarter. It is one of three locations for the CZ.NIC association, from which all infrastructure will be provided, including the infrastructure for the .CZ domain register. With private halls comes great emphasis on the ability to expand, on security and operation efficiency. Thanks to the new hall, they have 50 % more rack space and almost double the charging and cooling capacity. Physical infrastructure security has also significantly increased. With dedicated cooling, CZ.NIC also has better control over costs associated with operating the private hall. Touch to read more The interest association of legal entities CZ.NIC was established by leading internet service providers in 1998 and now has 118 members. The primary activities of the association include operating domain name register for domains registered under the CZ domain, ensuring the highest level of domain operation and educating the public about domain names. The association is currently focused on expanding DNSSEC technology and the mojeID (My ID) service), developing the domain administration system and supporting new technologies and projects that benefit the internet infrastructure in the Czech Republic. The association also operates the internal CZ.NIC-CSIRT security team and, as of 2011, the Czech national CSIRT team – CSIRT.CZ. In 2013, CZ.NIC was at the birth of the FENIX security project. CZ.IC is a member of the EURid association, which administers the European EU domain and other similarly oriented international organizations (CENTR, ccNSO and others). Who is CZ.NIC, z. s. p. o. Why CZ.NIC decided to move their servers to the private hall Zdeněk Brůna, Chief Technical Officer of the CZ.NIC association, provided an overview of the reasons that drove. Our technologies were located in shared data halls and physically secured via cages and further expansion was not possible. We nearly depleted all of the available capacity, cooling and charging, or electrical protection respectively. We contemplated various options for the necessary upgrade, including the building of an entirely new location, but out of all the options we had, the one that benefited us the most and was the least amount of risk was building a "private hall" with the data centre of České radiokomunikace, since upon migrating to the private hall, operating costs will not increase for the infrastructure. On the contrary, thanks to the migration, we now have the opportunity to reduce these costs. Zdeněk Brůna, Chief Technical Officer, CZ.NIC Kdo jsou Kdo jsou TOTAL SERVICE s.r.o.? How CZ.NIC benefited from the change The CZ.NIC association took advantage of migrating to a new, private, data hall to increase their capacity and, at the same time, had the opportunity to cut IT infrastructure costs thanks to using a different cooling principle. Besides the data centre service provider, we are the only subject in the private hall that influences the cooling efficiency (PUE coefficient). Better cooling efficiency (lower PUE) is achieved by having the private data hall build not only on the principle of warm and cool aisles, but also on the principle of improving the cooling efficiency by top cooling directly from the cool aisle. We will strictly limit the undesired mixing of warm and cool air. Additional savings can be achieved by cooling to a higher temperature. Reducing the PUE has an immediate and positive effect on billing for consumed power. This is very difficult to achieve with a shared data hall as you must also consider the needs and requirements of other customers.
