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.
Ready for the 10GbE generation
In addition to the default four Gigabit Ethernet ports (plus one dedicated port for the Heartbeat), RC18015xs+ comes with one PCI Express 3.0 x8 slot (running at x8 mode), accommodating installation of one 10GbE network interface card (NIC) for maximized bandwidth.
Award winning OS - DiskStation Manager
Synology DiskStation Manager (DSM) is a sleek, browser-based operating system running on every DiskStation and RackStation, which makes managing your Synology NAS a breeze. Featuring an intuitive user interface, DSM makes accessing and sharing your data smarter and simpler. Synology's Package Center lets you download and install useful add-on packages designed specifically for individual or business needs, meaning you can enjoy more entertainment in your life or better productivity at work.
Next generation data protection
As the first server in its class to feature the Btrfs file system, RC18015xs+ includes state-of-the-art data snapshot technology, allowing for flexible, point-in-time data backup and recovery.
Fit into business environments easily
With the support of Windows AD, LDAP, and Domain Trust, RC18015xs+ enables seamless account integration. The User Home feature can automatically create a "home" folder for every user account to minimize the administrator's effort in repeatedly creating "home" folders for all accounts. Windows ACL support on RC18015xs+ allows IT administrators to fine tune access controls and set up privileges to files and folders on RC18015xs+ through the familiar Windows user interface. With compatibility for major protocols, RC18015xs+ can eliminate server configuration overhead and enhance IT administrators’ efficiency
Unified storage system
RC18015xs+ enables businesses to cost-effectively manage multi-protocol data by integrating file-level (NAS) and block-level (SAN) storage into one unified storage system. Files can be shared across Windows®, Mac®, and Linux® platforms seamlessly with comprehensive network protocol support (CIFS/SMB, AFP, and NFS). RC18015xs+ provides a cost-effective iSCSI solution, allowing large scale businesses to consolidate storage into data center storage arrays. With thin provisioning available for file-level iSCSI LUN, you can maximize storage utilization by oversubscribing provisions and grow storage space as needed.
Synology CMS (Central Management System)
For enterprises with more than one Synology NAS server, CMS offers the flexibility and convenience for IT administrators to manage all of them from a single point of entry. Through a simple interface, you can obtain a clear overview on resource consumption and logs, helping you identify any issue right away. With group policies, CMS can do much more for your daily tasks. Once a NAS joins a group, it will automatically adopt its rules and behave as intended, without extra configuration.
Increase business productivity with cloud solutions
With comprehensive cloud solutions, RC18015xs+ lets you create your own private cloud easily. Cloud Station is the perfect package to sync files across multiple devices. Files can be edited in offline mode and later synced to Cloud Station, which keeps up to 32 historical versions, allowing you to restore a file back to previous version or recover deleted files. With the mobile app DS cloud, any change made to a file is automatically synced to your smartphones and tablets. For distributed enterprises, Synology's 2-way sync between different DiskStations ensures employees at different locations share the same information in real-time. IT administrators can handpick individual folders that they want to sync to different devices, manually or automatically based on file format and size. Folders synced by Cloud Station can be encrypted on DSM — no one will be able to access its content without your private key.
Secure your data
RC18015xs+ offers advanced security measures to protect you from potential security holes. Security Advisor analyzes system settings, password strength, network preferences and removes any possible malware. AppArmor blocks malicious programs from accessing unauthorized system resources. You can also customize the trust level in Package Center to avoid installing packages from untrusted sources, safeguarding your NAS from unknown or tampered files. In addition, RC18015xs+ provides other security add-ons, such as AES encryption, 2-Step verification, IP block & allow list, Antivirus packages, firewall, and DoS attack prevention
