Achieve the best capacity utilization among multiple QNAP NAS units

When I have multiple QNAP NAS units, or when I need to expand capacity on demand, how do I achieve the best utilization of NAS storage? Use

QNAP VJBOD (Virtual JBOD) to utilize storage resources of other QNAP NAS. VJBOD enables you to create virtual storage pools and volumes on

your local NAS. This will enable you to achieve the highest storage utilization of the multiple QNAP NAS in your environment.

Virtual JBOD

On-demand, instant storage capacity allocation

Remotely expand storage capacity

VJBOD is the QNAP implementation of software-defined storage and brings several benefits and practicalities to small and medium-sized business storage

architecture. Software-dened storage enables a high degree exibility and expand-on-demand capability. Use QNAP Virtual JBOD (VJBOD) to instantly allocate the

storage space from another QNAP NAS as an iSCSI LUN. Use the iSCSI LUN to create storage pools, take snapshots, make a clone from snapshots or index multimedia

les into the media library on the local NAS.

Enable the native iSCSI service and storage pool creation to allocate the capacity on it as Virtual JBOD. For example, a TVS-882 daisy-chained with six TX-800P

expansion units can have approximately 432TB raw storage capacity in total (calculated using 8TB HDDs). Further, the capacity can be easily expanded up to 1PB using

QNAP VJBOD.

* The support for iSCSI service and storage pool is required for the remote QNAP NAS. The maximum number of NAS for VJBOD conguration is 8

** QNAP VJBOD is only supported on the following models: X89, X82, X80, X79, X71, X70,X63, X53, IS-400. QTS rmware 422 or later is required.

With the networked and virtual expansion units, online capacity expansion with all available space among multiple QNAP NAS is made possible in lieu of

attaching a physical expansion unit. This also helps maximizing the utilization of storage resources.
