Almost all GPU servers (astra 2→9) are located in this room, where each server is provided whith redundant power supply and fast internet access and enough cool air. Recently (03/2018) the new storage server sto3 moved there as well and the configuration looks like this:

Tesla-9 and sto3 are connected via 10GB ethernet NIC's and the Netgear switch. Later on we can connect the other tesla's as well to t his fast 10GB switch. This combination gives fast access to data stored on the storage server (e.g. uploaded data from partners), for calculations on the GPU server, as well as output data on the storage server, provided the given mount points over the 10GB switch are used.
