Since 2005 we have been responsible for the network infrastructure of Dundee Precious Metals – a Canadian based, international mining company. We cover design, integration, migration, implementation and support at all company’s production sites: Canada, Bulgaria, Armenia, Namibia. We have designed the whole routing scheme for the corporate VPN which covers 4 continents and includes ~200 switches.
FreeBSD routers were used for the first Internet based VPN we made for DPM. The next step was to balance an IP VPN from a communication provider with a DMVPN over Internet for backup connectivity. In 2010 we collaborated with other companies for the migration to Cisco-based network and later we took the support of the whole network solution.
The unique underground LAN at Chelopech mine (Bulgaria) and Kapan gold mine (Armenia) we’ve built together with the company’s IT department. The underground LAN is complemented by a Wireless network for mobile users. The hard environment and the temporary tunnels needed a more flexible solution in order to provide WiFi network range just where the user needs it. That’s why we created the concept and supervised the production of a portable Wireless Extender (Cisco-based with MikroTik router board) with a battery.
We continue to support the Dundee Precious Metals network and to provide high level network design when requested.
In 2011 we designed and realized a Disaster Recovery project for DPM between two continents. The backup infrastructure for all of the company’s locations is based on IBM Tivoli Storage Manager (TSM) and combines physical and virtual tape libraries (VTL).
