Expansion Unit RX6025sas
High-density storage expansion for Synology HD6500 servers
Overview
Features

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.

Achieve peak performance with Synology drives
Synology drives’ finely tuned firmware ensures maximum integration with Synology hardware and software. Backed by a testing regimen that replicates heavy data center use, they deliver optimal performance and reliability even when tackling the most demanding applications.
