Enhancements

• Optimized performance of all-flash storage pools on dual controller NAS models.
• Predictive SMART migration can now be triggered by disk read/write errors.
• The UI now shows the location of system drive bays if there are no system drives detected at QES Initialization > Quick Setup.
• QES now blocks a firmware update when High Availability status is "Takeover", to avoid firmware inconsistencies between the - two controllers.
• Added warning status to disk I/O history and status.
• Upgraded SAMBA to version 4.7.

• The NFS service supports users being in more than 16 groups.
• SnapSync scheduling allows you to run a backup job every X hours.
• You cannot edit SnapSync host information after creating a job that uses that host.

• SMB 1 to SMB 3 are now supported. You can select the highest and lowest supported SMB versions, at Win/NFS > Microsoft Networking > Advanced Options.
• To enhance system stability, Storage Manager now limits the maximum number of disks allowed in one RAID group when creating or expanding a storage pool. The maximum number of disks depends on the RAID type. RAID 0: not limited / RAID 1: 2 / RAID 5: 3~9 / RAID 6: 5~10 / RAID TP: 8~11 / Triple Mirror: 3 / RAID 10: 1 / RAID 50: 3~9 per subgroup / RAID 60: 5~10 per subgroup

• Unable to retrieve storage information.
• Total allocated storage pool space was incorrectly reported if the storage pool was offline.
• The locate feature which blinks an HDD's LEDs did not work on EJ-1600 expansion units.
• In certain conditions, the NAS maximum snapshot limit was inaccurate.
• A domain user could not mount a SCB shared folder when SCA had taken over from SCB.
• A folder mounted via SMB/CIFS using the admin user credentials would stay mounted after the admin user account was disabled.
• Changed "REXP#1" to "Expansion Unit1" in the event logs.
• Improved the SAMBA search model.
• The system dashboard incorrectly displayed a warning status under certain conditions.
• Several minor bug fixes.
