Synology Rackstation Rc18015xs Storage

Features

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.

• CPU : Intel® Quad-core up to 3.7 GHz
• Memory : 8GB DDR3 ECC RAM, up to 32GB
• Ultra Performance : 2,153.26 MB/s reading
• Scalability : Up to 180 drives with 15 RXD1215sas

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 such as VMware vSphere, Microsoft Hyper-V, Citrix Xen Server, and OpenStack Cinder to enhance work efficiency. You can run and manage multiple virtual machines on Windows, Linux, or 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 and user quota settings provide comprehensive quota control on all user accounts and shared folder
• 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 and provides more flexibility for businesses
• Automatic file self-healing detects and recovers corrupted files without user intervention
