Disk Operations Using the RDR (Rapid Disk Resync)
Function
RDR (Rapid Disk Resync)
Models supporting the RDR function secure reliability by making disks duplexed per disk using the
ft control software’s RDR function. Duplexing disks by the RDR function enables the disks to be
resynchronized in a short period of time when their mirror has been broken due to causes such as
PCI module replacement
Setting RDR to disks duplicates the disks of paired slots as shown in the figure below and Windows
(ex. Disk Management and Device Manager) recognizes a paired disk as a single virtual disk.

Note:
In the above table, the PCI module names correspond to the following modules:
PCI module (for Group1): PCI module#1
PCI module (for Group2): PCI module#2
[Cautions for using the RDR function]
1.
RDR can be set only to the disks inserted into the built-in slots of NEC Express5800/ft series.
2.
Be sure to specify RDR to all disks inserted to the built-in slots and make duplex settings.
