The RAID concept (Redundant Array of Independent Disks) refers to several independent hard disks
which form a large logical drive when switched together. Redundancy information is calculated from
several data blocks (except for RAID 0) and saved distributed to the individual hard disks. Your
operating system no longer accesses the individual hard disks, but the array.
The actual objective of the RAID concept is to increase availability and prevent downtimes in the
event of a hard disk failure. However, the theoretical security of the RAID concept is only as good as
the RAID controller used. Benefit from the Fujitsu RAID controllers where technology, experience and
practical implementation all ensure the security that your company needs in the event of an emergency.
