NAS OS 4 supports SNMP, a standard Internet protocol for managing network devices such as printers, routers,
servers, and computers. Enable the SNMP agent in Notifications to give an SNMP server access your NAS OS 4
device. Additionally, the administrator has the option to turn on SNMP traps so that the NAS OS 4 device
Deleting data on a share permanently removes all associated files. By enabling the NRB service, deleted files
will be moved to the share's recycle bin. This can be very helpful if a user accidentally removes data that a co-
worker is using on a project. The data is easily recovered from the recycle bin rather than desperately
A logical unit number (LUN) is addressable data on an iSCSI target. Some versions of iSCSI management support
multiple LUNs on a single target. While NAS OS gives the administrator the ability to create one or more iSCSI
However, NAS OS 4 gives administrators additional options to help create and manage iSCSI targets. Rather
than creating new targets each time iSCSI is required, the administrator can export the LUN from an existing
.target and import the LUN's data. Additionally, NAS OS 4 includes the option to clone an existing target
NAS OS 3 prevented users from expanding an existing volume beyond 16TB. For example, a 14TB volume could
.not accept an additional 3TB for expansion. This limitation has been removed for NAS OS 4
Previous versions of NAS OS support connecting an uninterruptible power supply (UPS) to a NAS OS device via
the power and USB connections. UPS management is performed on the USB connection. If the working
environment experiences a loss of power, the UPS allows the NAS to save data before automatically shutting
NAS OS 4 gives the administrator greater flexibility in power management with network UPS. A single UPS can
now be used as a backup power solution for multiple NAS OS 4 devices. For example, the first NAS is connected
to the UPS via power and USB. This is the master NAS to the UPS and it acts as the UPS server on the network.
