Automatic VJBOD storage recovery after
auto-reconnection
Instant migration of VJBOD without physical plug and unplug
In addition to Missing mode protection of locally attached JBOD expansions, VJBOD employs an advanced
mechanism for disconnection prevention. If the remote NAS experiences a power outage, disconnection, or
change in IP address, you will get warnings via event notications in QTS. Further, the NAS will automatically
try to reconnect and recover the VJBOD storage without user intervention.
Typically, to migrate an expansion unit, you would need to manually plug and unplug the device and transport it to the destination. However, with the VJBOD that can
be connected using iSCSI and safely detached as a storage pool in Storage Manager, virtual disks that have been detached from your NAS can be used again on other
NAS. Thus, the data and application on the virtual disks can be accessed on other NAS and shared among dierent QNAP NAS devices.
*For virtual disks that have been connected via iSCSI targets to be used in Virtual JBOD, they should be excluded from other iSCSI initiator connections.
Redundant network architecture to increase reliability of VJBOD
Online capacity expansion over the network does not cause an associated instability of storage space utilization. QNAP NAS equipped with two or more Ethernet
ports supports port trunking (link aggregation with multiple LAN ports). Compared with single-LAN transmission, port trunking increases the bandwidth of your NAS
and provides fail-safe trac to maintain network connectivity in the case of a connection failure. Furthermore, with port trunking, network trac will automatically
achieve load balancing for each connected device.
