Understanding Volume Management
The ReadyNAS Duo uses X-RAID, an NETGEAR-patented expandable RAID technology. Some
benefits of X-RAID technology are:
•
One-volume technology, but supports volume expansion, either by with the addition of more
disks or the replacement of an existing disk with larger capacity disks.
•
You can start out with one disk, and add an additional more disk when you need it.
•
Volume management is automatic. Add a second disk, and it becomes a mirror to the first—the
expansion occurring while redundancy is maintained.
Volume Management for X-RAID
The X-RAID technology offers a simplified approach to volume management. X-RAID works on
the premise that what most people want to do with their data volume over time is either adding
redundancy or expanding it without the headaches usually associated with doing that. By using
simple rules, X-RAID is able to hide all the complexities yet provide volume management features
previously available only in enterprise-level storage solutions.
•
X-RAID Redundancy Overhead
. To maintain redundancy from disk failure, X-RAID
requires a one-disk overhead. In a two-disk X-RAID volume, the usable capacity is one disk.
