GE-01-GRENA – Georgian Grid infrastructure


In 2009 Georgian Research and Educational Networking Association GRENA established the first Grid facility in Georgia GE-01-GRENA, which is included in the European Grid Infrastructure. Last upgrade of the system took place during 2013-14, when 2 working nodes (DELL PowerEdge R720) and storage system (DELL PowerEdge R720 XD) were installed. In 2013 Tbilisi State University and GRENA established Certification Authority. GE-01-GRENA site is located at GRENA data center and its elements are interconnected with Gigabit Ethernet. Data center is connected to the GRENA backbone with three 1 Gbps capacity links. During 2016 these links will be upgraded to 10 Gbps. The Data center is equipped with redundant power supply system (2 generators and 2 UPS) and cooling system. The technical information is provided in the table below.
