Technical solutions

For our cloud services we exclusively use technological equipment of leading suppliers DELL and CISCO. To avoid outages, the technical solution is built on redundant infrastructure, in two geographically independent areas. By this step we ensure high availability and flexibility of our services, regular backup and data protection.

Diagram of connection and used HW

The primary data center is located in the Zoner office building. Backup and replication software for off-site backup and Disaster Recovery (backup operations of your systems) is located in the secondary data center Kovoterm on the street Cejl in Brno.

The connection is provided by an optical circuit with two physically independent routes which guarantee the connection of the sites even if one of the optical link is discontinued. Connectivity is assured by two different providers, first connected in the primary and the second in the secondary data center.

We are also a member of the BR-IX peering node in Brno, which we use for direct peering with many important IT companies in the Czech Republic and Slovakia.

Routing and receiving connectivity is done using two 10Gbit CISCO routers. In the primary datacenter we use Dell converged backbone switches connected with 2x 100Gbit link. The rest of the LAN and SAN infrastructure and optical circuit use 10Gbit lines, with a planned switch to 25Gbit to the future. Individual blade chassis and iSCSI storages are connected to the backbone switch.
