To expand a SmartExtend volume, please open the administration page of the SmartExtend target
system. When the target volume is connected to the initiator, use the Volume
ÆExpand function
to expand the target volume.
5.5 Migrating Data Volumes
Migrating a data volume is to duplicate a volume block by block. It helps administrators migrate or
duplicate data between volumes of different RAID types or capacity. During data migration, both
the source volume and the target volume will be un-mounted, not available for client access.
To migrate data, select a source volume, and the target volume to migrate to. Choose Data
migration and click Apply. The target volume will inherit all the security and quota settings of the
source volume. No differences will be observed by clients before and after the migration.
To duplicate a volume, select a source volume and the target volume. Choose Data duplication
and click Apply. The target volume will stay on-line after the data duplication.
5.6 SmartExtend – Add More NAS Capacity
The SmartExtend feature can add NAS capacity over LAN. A SmartExtend initiator can connect
up to 10 SmartExtend target volumes via the Giga- or Fast-Ethernet ports. A target volume can
provide up to 2TB of capacity, so it can increase NAS capacity by as much as 20TB.
The following table explains some terms used by SmartExtend.
SmartExtend Initiator A NAS head. It can add more capacity by connecting with
SmartExtend target volumes over network. A SmartExtend
initiator can connect to 10 SmartExtend target volumes at
most.
SmartExtend Target A system which contains target volumes. Target volumes
are used to add capacity to a SmartExtend initiator.
SmartExtend Target Volumes JBOD or RAID groups on a SmartExtend target system.
SmartExtend
Network-Attached Devices Once connected, SmartExtend target volumes appear as
free disks on a SmartExtend initiator system. Different from
a locally-attached hard disk, a SmartExtend device is
network-attached.
Exported SmartExtend Target
Volumes Target volumes must be exported to network first before
being seen and used by SmartExtend initiators.
Group Allowed/Login User The use of a SmartExtend target volume is restricted to the
SmartExtend initiator and the user group which are
assigned when it is exported. Only the specified
SmartExtend initiator can use the target volume. And the
initiator must provide a user account for authentication
when it tries to connect to the target volume.
