    • Updated Privacy Statement and related settings in the installation flow.
  2. iSCSI Manager

    • Brand new iSCSI Manager built for IT administrators, providing a new management user interface for an optimized iSCSI management and monitoring experience.
    • Advanced LUN provides lightning-fast LUN snapshot creation and recovery, and LUN cloning within seconds, as well as VAAI/ODX, storage acceleration commands, and support for better VM performance. Since Advanced LUNs can utilize file system cache to provide better efficiency, block-level LUNs will no longer be supported on DSM 6.2 and onward. DSM 6.2 will still be compatible with the block-level LUNs upgraded from DSM 6.1 and prior.
    • Supports cross-volume LUN clones.
    • Added support for network binding settings to allow each iSCSI target to map to a network interface.
    • Users can now disable storage reclamation for thin-provisioned LUNs to enhance I/O performance.
  3. Storage Manager

    • The brand new Overview shows the health status of all storage components on your NAS, displaying a clearer and better look on the system overview.

    • Introduced Storage Pool, a new storage component, to replace the original Disk Group and RAID Group, and rearrange storage-related functions to provide users with a more consistent and smoother experience.

    • Smart Data Scrubbing detects the supported file system and RAID type to perform data scrubbing automatically while enhancing data scrubbing usability. A new built-in scheduler allows users to do data scrubbing periodically with just a few clicks, improving data integrity and consistency.

    • RAID resync speed can now be adjusted to accommodate IT management needs.

    • Users can remotely deactivate drives via Storage Manager for better management.

    • Added a default monthly S.M.A.R.T. test on both new and existing drives that were not previously configured.

    • After each DSM upgrade, DSM will remind users if a bad sector or lifespan alert is not set up.

    • The health status of disks is now uniform with storage pools and volumes.

    • Log Center now includes disk logs.

    • Provided an option to change stripe cache size when the RAID type of Storage pool is RAID 5, RAID 6, RAID F1, or SHR (three disks or above).

  4. High Availability Manager 2.0

    • High Availability Manager has been modularized into a package to ensure better system maintenance and offers greater update  flexibility.

    • New mechanism can now eliminate unnecessary system reboot during major update to keep your cluster secure and maintain high service availability.

    • SHA 2.0 can handle situations more effectively especially when the servers are in a vulnerable state.

    • A simpler yet more intuitive user interface,  offering you a comprehensive cluster overview and management.

    • The new interface design provides more detailed and visual information as well as easy-to-follow solutions.

    • Brand new user interface is introduced to display more details of both active server and passive server, giving you an in-depth system utilization overview.

    • When first creating SHA cluster, user new to SHA can choose to only replicate system configuration to shorten setup time.

  5. Extended Btrfs File System Coverage

  6. Azure AD support

    • Added the capability to join existing Azure AD as an SSO client. Utilizing the single sign-on feature, daily productivity is increased by saving time spent on re-authentication.
