Synology high-availability cluster integrates two RackStation RC18015xs+ as dual computing nodes and multiple Expansion Unit RXD1215sas as shared storage units, providing the secure, reliable, and superior-performance network attached storage solution for large scale businesses.
Reliable Active/Passive Failover Cluster
System and service availability is critical for businesses. However, server component, environmental problems, human errors, or system malfunctions happen sometimes that might lead to service interruption and raise the cost of running businesses. Synology high-availability (HA) cluster solution is born to alleviate this problem by combining two RackStation RC18015xs+ and multiple Expansion Unit RXD1215sas as one HA cluster. The two RC18015xs+ computing nodes provide Active / Passive automatic failover. If the active server suffers a malfunction, the passive server is able to provide quick relief by taking over all the running applications and services, ensuring high levels of availability.
The connected RXD1215sas acts as the shared storage pool of the two servers, so no data replication is required, saving more energy and rack spaces. The storage capacity is expandable by adding more RXD1215sas (up to 15 sets) to the HA cluster, providing the scalability up to 180 HDDs and a maximum raw capacity beyond 1 petabyte.
