QNAP Flexible Volume
QNAP Flexible Volume provides a more secure and flexible way to store and manage the NAS data. This next generation volume offers powerful features such as storage pooling with multiple RAID, thin-provisioned volume with space reclaim, and online capacity expansion.

QNAP Flexible Volume

Block-based iSCSI LUN
In addition to storing data, the QNAP Flexible Volume can be utilized as an iSCSI LUN at the same time. The block-based iSCSI LUN provides less overhead which improves the overall read/write performance. The blockbased iSCSI LUN takes advantage of Flexible Volume features such as thin provisioning LUN with Space Reclaim and online capacity expansion.

Online Capacity Expansion
Increase the capacity size of the LUNs, volumes, and storage pools on the fly. The Turbo NAS allows you to add more hard drives to increase the storage capacity of the storage pool on demand. The LUN and volumes can also be expanded online without interrupting the services.

Thin-provisioned Volume
Pre-allocate storage to give the appearance of having more capacity than actually available. This allows you to consume storage on demand as data is written to disk, instead of having capacity ahead of time.

Space Reclaim
Space reclaim complements thin provisioning so storage can be recovered and used for other NAS applications. Normally when data is deleted in a volume the storage capacity cannot be transferred back to the overall storage pool. But with space reclaim, space can be recovered and allocated back to the overall storage pool. This provides a much more efficient space usage.

Alert for Volume/LUN Threshold
An alert can be created once a LUN or volume reaches a particular threshold size with email and SMS notifications. This prevents the storage or volume from running out of space, and the administrator can add more storage space or expand an existing volume if necessary.

App Center

Powerful, organized, rich-in-content
