Operating systems by usage

The RAID Support column indicates whether the distribution natively manages to install it in RAID (obviously if you have chosen a Dedibox with RAID option)

The fact that a distribution does not support RAID, does not mean necessarily that it did not manage at all, it means only that you may need to set it up “by hand” after the installation completed.
During the first start of a Dedibox configured to use RAID, it may take up to 30 minutes before the system becomes available (this corresponds the the build time of the RAID on Linux, in which the machine is inaccessible!)
