Your ReadyNAS storage system supports X-RAID™ mode, a proprietary single-volume
RAID architecture that is easy to administer, and Flex-RAID mode, which allows you to
format your disks in a variety of industry-standard RAID levels.
When you power on your system for the first time or if you reset your system to its factory
default settings, the optimal RAID mode and level are automatically selected for you
based on the number of disks that are installed. You can also configure the RAID settings
manually (see Change RAID Mode on page 29).
RAID Group
In ReadyNAS OS, a large RAID volume can be organized into RAID groups. RAID groups
can improve performance by striping, as it distributes I/O across more of the disks.
During the process of creating a volume large enough to support RAID groups,
ReadyNAS OS selects an appropriate RAID group structure for you. You can override
this automatic structure before the volume is actually created.
X-RAID
X-RAID is an autoexpandable RAID technology that is available only on ReadyNAS
systems. With X-RAID, you do not need to know intricate details about RAID to administer
your system. X-RAID allows you to add storage space without rebuilding or moving your
data to another location. Because the expansion happens online, you can continue to
use your ReadyNAS system while the volume capacity increases.
Note: Previously formatted disks must be formated by your ReadyNAS system prior to
you adding them to an X-RAID volume.
Because X-RAID is a single-volume architecture, if you configure your hard disk drives
to use X-RAID, your storage system includes only one volume that is made up of all
installed hard disk drives. X-RAID’s single-volume architecture provides two major
advantages:
•
Easy system management
•
Auto expansion
Adding disks to a Flex-RAID formatted system is more complex. Disks must be added
in ways that are compatible with the RAID level. Alternatively by deleting the volume
and recreating it, you can completely change the RAID level of the volume. With X-RAID,
none of those administrative tasks are required. Instead, with X-RAID, your volume
automatically expands to accommodate additional disks or larger-capacity disks.
With X-RAID, you can start out with one hard disk, add a second disk for data protection,
and add more disks for additional storage capacity. X-RAID accommodates the new
disks automatically. You can replace existing disks with larger-capacity disks and X-RAID
automatically accommodates the new disks.
X-RAID requires a minimum of two hard disks to provide protection against disk failure.
