    • 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.

    • 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.
