Switches

Currently two switches are used in the server room.

  1. Brocade VDX 6740
  2. Dell S4048-ON

Brocade VDX 6740

The Brocade switch is controlled by the RBG and builds the backbone of the server infrastructure, connecting every server with each other trough a 10Gb/s link.
The switch has an uplink to the rest of the informatics building network and is controlled trough vlans. VLAN 83 is our chair network (131.159.24.0/23) and VLAN 133 (10.0.0.0/8) is the internal server network. Each interface can be assigned to a specific or multiple VLANs.
There are only 24 licenses, so only 24 servers can be connected with 10Gb to the switch.

Dell S4048-ON

Service Tag: H1K2Y42

The Dell switch is used in the Emulation Cluster, connecting the 12 servers with two interfaces each (10Gb/s). The switch has Dell Networking OS 9 running (FTOS10) and is controlled from one Emulations Server (Controller: emu02-cm). The Controller is directly connected to the management port of the switch.

To connect to the switch use the following approach:

Firmware Upgrade

The latest firmware can be downloaded from the force10 network. To get a user account a form needs to be filled out on the website with the service tag of the switch and other information. Download the latest firmware of the Switch model (S4048-ON not S4048T-ON !!). The file is something like “FTOS-<Version>.bin” you don't need the ONIE installer file. Check the md5sum of the downloaded file to make sure it didn't get corrupted while downloading. Then transfer the file to emu02-cm.in.tum.de to the home folder of i11 /home/i11.

After the restart you should have a perfectly working Switch with the same configuration as before but with a newer firmware version. Be aware that the reload command takes down all the network Ports temporarily!
