Synology SYNOLOGY RACKSTATION 12-BAY RACKMOUNT EXPANSION UNIT RXD1215SAS

High-availability cluster design By combining two computing servers and multiple storage units into a single high-availability cluster, RC18015xs+ and RXD1215sas deliver unyielding reliability and data availability. With the active/passive structure, services are automatically switched over to one server if the other unexpectedly goes offline, helping your business avoid costly downtime. Massive scalability up to 180 drives Up to fifteen RXD1215sas can be connected to the dual RC18015xs+ computing nodes2, accommodating massive scalability up to 180 drives and maximum raw storage beyond 1PB3. The shared storage architecture eliminates the need for data replication over the network, in addition to drastically reducing deployment costs. Hardware redundancy enhances system uptime In addition to the active/passive architecture, RC18015xs+ and RXD1215sas are equipped with redundant hardware components, such as power supply units, SAS modules, SAS connection cables, system fans, LAN ports, and even the Heartbeat connection. In the event of component failure, the system continues operating normally while replacement parts are obtained and installed.
