No need to describe it – google Quadstor to find out more. Here is a simple way to install on Debian 7 Net Install (64 bit of course):
apt-get install uuid-runtime build-essential sg3-utils apache2 psmisc linux-headers-`uname -r` ntp git sudo
vi /etc/ntp.conf
service ntp restart
cd /root
git clone --branch opensource https://github.com/quadstor/quadstorvirt.git quadstor
cd quadstor
./installworld debian7
