Description
High-availability cluster design
By combining two RC18015xs+ and at least one RXD1215sas, the Synology high-availability cluster1 delivers 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.
Hardware redundancy enhances system uptime
In addition to the active/passive architecture, RC18015xs+ is equipped with redundant hardware components, such as power supply units, internal system fans, and LAN ports, to optimize service continuity.
Scalable to 10GbE, and beyond
The PCIe 3.0 slot allows for faster networking as you expand your infrastructure. Together with the built-in quad Gigabit ports, RC18015xs+ offers comprehensive connectivity options for link aggregation and failover configurations.
Complete iSCSI and virtualization solutions
Synology iSCSI storage supports most virtualization solutions including VMware vSphere, Microsoft Hyper-V, Citrix Xen Server, and OpenStack Cinder, to enhance work efficiency. Create and manage virtual machines running multiple operating systems such as Windows, Linux, and DSM using Virtual Machine Manager.
Next-generation file system for better data protection
The Btrfs file system introduces advanced storage technologies and optimized snapshots to prevent data corruption and reduce maintenance overhead. While ensuring high-level data integrity, it also offers flexible, efficient data protection and recovery tools.
Flexible Shared Folder / User Quota System provides comprehensive quota control on user accounts and shared folders
Snapshot Replication provides schedulable and storage capacity-saving data protection with 1,024 shared folder backups and 65,000 system-wide snapshots
File- or folder-level data restoration accelerates data recovery, providing more flexibility for businesses
Automatic file self-healing detects and recovers corrupted files without user intervention
