ZFS - the best file system for business data storage
The ES1640dc features ZFS, a combined file system and logical volume manager, to support various advanced functions for high-end enterprise storage, including powerful storage expansion, flexible storage pools, simplified management, high-performance SSD cache, nearly limitless snapshots and cloning, data deduplication, in-line compression and thin provisioning with reclaim for optimized utilization for virtual machine storage. ZFS is designed with a focus on data integrity, and uses its end-to-end checksums to detect and correct silent data corruption caused by hardware defects, bugs in firmware or metadata errors, effectively protecting user's data.
Deduplication and compression to maximize VDI storage performance
There could be over 90% duplicate data from OS images and applications that are spread over virtual desktops. The ES1640dc supports block-based data deduplication to optimize storage usage from redundant data. Deduplicated virtual desktops become easier to be cached to achieve optimal virtual desktop performance. In-line data compression helps shrink data size, further optimizing storage usage. For mastering storage in a virtualized environment, the ES1640dc provides businesses with the most cost-effective remote virtual desktop platform and mission-critical information warehousing.
Strong disaster recovery made by nearly limitless snapshots and SnapSync
The ES1640dc supports up to 65,536 snapshots for iSCSI LUN and shared folders. When executing a remote snapshot backup, it only needs to transfer changed data, and can use deduplication and compression to significantly reduce the amount of transferred data. The ES1640dc can provide remote backup SnapSync for snapshots at the shortest interval of every five minutes, fully supports VMware vCenter Site Recovery (SRM) technology, provides Storage Replication Adapter (SRA) for SRM, and provides enterprise-class remote backup & disaster recovery solution to fulfill business continuity.
