Update: the maintenance is complete and only took 32 minutes to complete.
We bought three units of Supermicro SuperServer 5038ML-H12TRF a couple of months ago. Each SuperServer system consists of 12 nodes, where each node is equipped with an Intel® Xeon® E3-1271v3 3.6GHz processor, 16 GB RAM, and 2x1 GbE Intel NICs.
We deployed one of these systems in Stockholm on September 10th, and it's time to deploy another one of them in Gothenburg now due to the increase of traffic we've seen there. The blade server will replace the current six VPN servers in Gothenburg.
The maintenance is set to be four hours but should be substantially shorter than that. The blade system consists of 12 servers, which means we'll be adding a total of six new servers:
