+## More about server100
+
+So, what kind of server is this server100 anyway? It is a 24 bay,
+Supermicro X9QRi-F with 64 cores and 512GB RAM. It is connected to our
+network with 2x 10 Gbit/s network cards running LACP bonding. Not only
+in terms of computing it is big, it is with it's 1620W PSU also one of
+the "heaviest" servers in our data center (the average PSU is
+rated somewhere in the 1000W area).
+
+Some more insights coming from the terminal:
+
+```
+[17:33] server100.place10:~# cat /proc/cpuinfo  | grep ^process | wc -l
+64
+[17:33] server100.place10:~# free -g
+              total        used        free      shared  buff/cache   available
+Mem:            503           0         502           0           1         501
+Swap:             0           0           0
+```
+
+Obviously, the uptime is not yet that high...
+
+```

+ 17:46:42 up  1:37,  load average: 0.00, 0.00, 0.00
+```
+
+... neither are the measured temperatures:

+As you can see, we have a lot of fun with our latest servers. And this
+brings us to the important point: celebration.
