Configuration 4 - Fujitsu Eternus2000 Manual

High reliability supports 24/7/365 operation
• Duplication of important components
Important components such as controllers, power supply units, and fans are duplicated to continue the
operation in the case of unexpected failure. Also this allows the hot swapping of failed components
with the device power on. In addition, the latest firmware can be applied during system operation.
• RAID6 responds to the double failure of disk drives
ETERNUS2000 supports RAID6, using two parity disks in one RAID group. RAID6 ensures the data
safety in the unlikely case of a fatal second malfunction within a single RAID group. Also the
ETERNUS2000 supports RAID1, RAID1+0, and RAID5 to realize the flexible RAID configuration.
• Redundant copy ensures disk drive redundancy
ETERNUS2000 diagnoses the disk drives to detect the failure prediction. When the disk drive requires
preventive maintenance, ETERNUS2000 automatically copies the data in the target disk drive to
ensure data redundancy.
• Block Guard ensures data integrity
ETERNUS2000 adds check codes and check them at multiple checkpoints on data transfer path to
ensure the data integrity.
