Storage: Unleash the full advantages of SSD, streamline storage management and data recovery [Watch presentation video]
Software-defined SSD extra over-provisioning: Configure SSD RAID over-provisioning to diminish undesired SSD write amplification for maximized SSD lifespan, and to achieve a constant random writing performance of over 100% compared to SSD with only the default over-provisioning amount. It is beneficial for boosting write-heavy applications such as databases and intensive online editing. A SSD Profiling Tool helps evaluate the over-provisioning ratio based on the target IO/s performance of users.

Restoring from remotely-stored snapshots: Snapshot restoration from a remote snapshot replica can now be directly written back to the local NAS through the network without manually restoring all folders and files at the backup destination then copying them back to local NAS. This saves time and effort by streamlining operations.
Flexible volume configuration and conversion: Volumes can now be converted between thin- and thick-provisioning, providing flexibility of storage space allocation. Volumes sizes can be shrunk as well, ensuring the NAS can adapt to changing needs of storage allocation.
Boosting VJBOD performance with iSER: The company’s proprietary Virtual JBOD (VJBOD) technology is boosted by iSCSI Extensions for RDMA (iSER) support from Mellanox Technologies, Ltd. compatible network cards, enhancing transmission speeds for a more efficient storage expansion.

Software-defined network and Virtual Switch app: Revamped with features including network topology, device diagram to identify physical ports, customizable multiple DDNS, NCSI service, static route, software-defined switch mode, IPv6 complete function, and DHCPv4 reserved IP addresses, the app greatly streamlines operations and improves performances at the center of the user experience. UI improvements for Thunderbolt and wireless settings make their statuses more straightforward and settings more convenient.
Advanced support for SmartNICs: QTS now supports features that are built into advanced network interface controllers (NICs), such as the Mellanox ConnectX-4 for iSCSI Extensions for RDMA (iSER).
QBelt VPN protocol: The firm’s proprietary QBelt VPN protocol added into the QVPN Services app increases network security by encrypting traffic and decreasing chances of being detected. Geo-blocked web content and/or enterprise intranet resources can also be accessed by using QBelt to circumvent such restrictions.

More features include:
