With a built-in intelligent algorithm, DS effectively reduces the data written to the NVMe SSD and extends its service life, which helps to avoid simultaneous failure of multiple SSD and enhance data protection. For minimising IT management burden, it also predicts the remaining life (days) of the SSD based on the workload, and actively send out notifications to remind users when SSD replacement is needed. All storage-related settings can be configured in an easy-to-use SANWatch management interface. DS is equipped with a complete data protection mechanism: while multiple RAID levels prevent data loss due to hard disk damage, snapshots and remote replication functions realize local and remote data backup, and supercapacitor ensures that data is not lost when the system is powered off. The complete product line of DS satisfies performance and budget requirements of small and medium businesses to large enterprises.
