Gina specifications

Gina is the Grid cluster at SURFsara; currently all the servers are located at the Digital Realty datacenter. After different tenders these servers belong to different brands (Dell & Fujitsu). Three service nodes are used to host virtual machines for different purposes (creamces, monitoring, installation, dns servers…). All the worker nodes are installed on physical nodes.

Network

GinA and Grid storage share a network backbone, connected with a high throughput network. Currently we have seen over 20GB/sec (~170-200Gbit/sec) of peak network traffic to the Grid storage. All workernodes are connected with a single 10Gbit or 25Gbit ethernet connection.
