## 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] server100.place10:~# uptime
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.
