DSM
iSCSI Manager
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).
