Operating system (OS) RAID
The OS RAID comprises two S-ATA 2.5 inch Hard Disk
Drives (HDDs) which are mounted in the front section of
the server unit, located on top of the Media RAID.
The HDDs are configured in a 'mirror' arrangement that
creates an exact copy (or mirror) of a set of data on two
both disks. This is useful when read performance or
reliability are more important than data storage capacity.
This is called 'fault tolerant' because if one of the mirrored
drives suffers a mechanical failure (e.g. a spindle failure)
or does not respond, the remaining drive will continue to
function.
OS RAID control is implemented by software, unlike the
Media RAID which is controlled by the PCI RAID
Controller Card.
DC power supplies for the HDDs is routed via the
Motherboard, the System Power Board and the Slim
Power Distribution Board.
