QES – Designed for high-end enterprise IT environments

  • Suited for enterprise-level storage with maximized business continuity by adopting ZFS that focuses on data integrity.

QES supports deduplication and compression to maximize VDI storage performance

  • QES supports block-based data deduplication to reclaim storage used by redundant/repeated data and in-line data compression to shrink file sizes.
  • Both functions optimize storage utilization and provide cost savings for businesses when using SSDs (particularly for all-flash storage deployment).
  • In VDI environments where there could be over 90% duplicate data from OS images and applications that are spread over virtual desktops, deduplicated virtual desktops become easier to be cached to achieve optimal virtual desktop performance.

QES streamlines remote backups with nearly limitless snapshots and SnapSync

  • QES supports up to 65,535 snapshots for iSCSI LUN and shared folders (if 1 snapshot is created every hour, 24 snapshots per day, then up to 7 years worth of snapshots can be created without needing to delete any), and replicates snapshots to remote servers by using block-level SnapSync.
  • In the event of a primary site failure, the complete and efficient SnapSync assists businesses to resume essential services in the shortest time.

Ideal backup NAS for Enterprise ZFS NAS
