====== CDE D2 serverroom ======
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:

^ rack ^ number ^
| rack | 4 |
^ device ^ rack location ^
| netgear 10GB switch | U12 |
| astra-tesla-9 | U10-11 |
| sto3 | U5-9| 
| astra-tesla5-9 | U1-4 |

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.
