SSD Storage is the name of the volume OS X is installed on. OS X 10.7.5 clean install.
You can't upgrade OS X Lion to OS X Lion Server. You have to start with a OS X Lion Server install.
Bringing up the log window (I think the installer had a log window back in 10.7) may also give more detailed information.
Install.log (in /var/log) will be more helpful than "All messages"

As I said in the beginning... You can't upgrade Lion to Lion Server. You have to start with a Lion Server install. According to this line:
Running OS Build: Mac OS X 10.7.5 (11G63)
It appears that you have OS X Lion installed on your Xserve, not OS X Lion Server.
Mac OS X Server Update Combined can't be installed on this disk
