Data Fault Tolerance
Your Express5800/320Ma system offers two methods of ensuring data fault tolerance
and continuous availability of its disk media:
•
Rapid Disk Resync (RDR), a disk-replicating technology, is supported only on the
internal disk drives.
To create striped volumes across the mirrored internal disks, refer to the
documentation for your disk-management tool.
You choose to implement RDR, for internal disk drives, or volume-mirroring, for all
disks, during the software installation and configuration procedure. However, you can
upgrade your disks to RDR after software installation.
