Massive storage expansion Designed for service uptime SAS multipathing Redundant components Plug-and-play deployment Achieve peak performance with Synology drives Synology has you covered Massive storage expansion Accomodate growing storage demands by adding 60 additional drives to your HD6500 in minutes. Support for up to four expansion units enables seamless storage growth without costly disruptions. Support for SAS multipathing provides up to double the performance when deploying multiple expansion units, while online storage expansion and the comprehensive management tools in Synology DiskStation Manager (DSM) streamline setup and ongoing management. Designed for service uptime Tackle large-scale applications while maintaining the highest level of service availability thanks to clever hardware solutions. SAS multipathing SAS multipathing maximizes resiliency against hardware malfunctions by providing alternate physical paths, allowing the system to reroute data when the primary interface or connection fails. Redundant components Modular drive trays and system fans reduce the impact of maintenance on service availability, allowing for easy and quick replacement. Redundant power supply units provide continuous data availability even during power source failures. Plug-and-play deployment Minimize downtime when expanding your storage infrastructure with online storage expansion, which allows you to add new volumes or expand RAID volumes on the RX6025sas without affecting services on the HD6500.
