1.1.3 System Protection

The DNS-3000 is designed for network file services and is available with
industrial standard hardware RAID and Web interface remote manage-
ment for successful upgrading and increased stability and reliability of
the system.
To increase reliability, the DNS-3000's operating system comes with
RAID 1N technology when released from the factory, where the first 10
GB of the hard disk is kept for Mirroring and the operating system is
installed in the area. If several hard disks experience problems, the user
can still boot the operating system. Users may also use Mirror Split to
divide the operating system that has been installed, enabling a dual oper-
ating system mode. If the primary operating system is damaged or not
available, the backup system will boot up the unit for service while the
damaged operating system remains separate for repairs.
Note: For details on installation of the dual operating
system and repair of the operating system,
please refer to System Protection and Repairs.
For protection of the data split area, the DNS-3000 is available with a log-
ical region on the hard disk excluded from the space for the operating sys-
tem. The operating system uses RAID 5 technology when released from
the factory. In that mode, when a hard disk is damaged, data remains
accessible as usual.
Each and every DNS-3000 is available with a SATA hot plug hard disk
when released from the factory plus 2 logically split areas. Data in the
split areas are available in the following tables and figures.
