NEW IN VERSION 4.4.4
Replication Performance Improvements – Buurst SoftNAS has switched to ZSTD compression for replication transfers for a performance improvement gain of up to 40% through faster data replication. More info on ZSTD can be found here: https://facebook.github.io/zstd/
Lift and Shift Improved File Scan Performance – Scans of Lift and Shift source locations with a high number of file system objects are now much quicker. In lab testing, a source with 1 TiB of data and 1.5 million objects was cut from 92 hours to 4 hours, using 1 GbE networking.
ENHANCED IN VERSION 4.4.4
Updated ZFS to v0.8.3-3 – This ZFS upgrade addresses a potential ZFS panic issue with send/receive VERIFY3 operations.
Lift and Shift Pool Creation – The pool creation process has now been optimized to provide better feedback if invalid parameters are provided.
SmartTiers enhancements – Several fixes to the SmartTiers feature have been implemented:
- Resolved an issue in which migration policy settings were not retained after a reboot.
- Resolved an issue in which expansion of SmartTiers storage could potentially result in data corruption.
- Resolved issues related to data consistency during SmartTiers migration of data between tiers.
- SmartTiers UI now displays consistent usage status.
SnapReplicate and SNAP HA – Several fixes to the SnapReplicate and SNAP HA features have been implemented:
- Unsupported SNAP HA recovery options within the UI for the VMware version are no longer visible to the user.
- Previously, the snapshot weekly retention policy defaulted to zero. The default has been changed to 1 to ensure that snapshots are retained at least one week unless otherwise specified.
- Resolved an issue in which a mismatch between the mbuffer block size and the SnapRep block size could result in memory fragmentation that impacts performance.
