1.2.1. Configuring RAID using 4 HDD (1U)

For the 1U appliance (FS-412) Tandberg Data recommends two logical
Volume sets consisting of System Volume (SV) and Data Volume (DV) to be
created within the RAID set. The RAID set is first created which comprises of
member HDD (number of HDD in a set). The two logical volumes (SV and
DV) are then allocated from aggregated capacity of the RAID set with the
desired RAID levels. The System Volume, installed with the host operating
system, is organized as RAID 0+1 and the Data Volume is organized as
RAID 5. This is to allow OS redundancy if more than one HDD fails. Please
see the Viking Series NAS Hardware User Manual for details.
The volume layout for the appliance is illustrated below.
