RackStation RS18017xs+
Engineered for scalability to meet any storage demands, Synology RackStation RS18017xs+ provides reliable, high-performance network attached storage for enterprises seeking flexible storage solutions. With scalability of up to 180 drives, RS18017xs+ allows simple data management with minimal time investment required for setup and maintenance.

Powerful Storage Solution with Ample Upgradability
Powered by an Intel Xeon D-1531 6-core CPU and 16GB DDR4 ECC RDIMM (expandable up to 128GB), Synology RS18017xs+ is the ideal companion for intensive data processing, video post-productions, and virtualization applications that increasingly require more storage space.

RS18017xs+ comes natively with dual 10GBase-T ports and four Gigabit ports, along with two 8-lane PCIe 3.0 slots for additional high-performance network interface cards (NICs). When configured with 6 x 10GbE ports with Link Aggregation enabled, RS18017xs+ provides ultra-high sequential throughput at over 4,800 MB/s and 568,000 sequential IOPS.

RS18017xs+ features 12 x 3.5" drive bays in a 2U form factor and allows pairing up to 7 expansion units for a combined 180 drives or 96 drives when paired with Synology Expansion Unit RX2417sas or RX1217sas respectively.

  • 7 x RX1217sas for additional 84 x 3.5" / 2.5" SAS / SATA HDD / SSD drives
  • 7 x RX2417sas for additional 168 x 2.5" SAS / SATA HDD / SSD drives

Rock-Solid Data Protection
The Snapshot Replication application provides schedulable, near-instantaneous data protection. It replicates 65,000 system-wide backup copies to offsite servers and local volumes, bringing near-instantaneous data protection and ensuring data in shared folders or virtual machines in iSCSI LUNs remain available in the event of a disaster.

With block-level incremental backup and cross-version deduplication, Synology Hyper Backup provides multi-version backup with optimized storage space utilization and allows multiple backup destinations to local shared folders, external hard drives, network shared folders, rsync server, and public cloud services.

Btrfs: Next Generation Storage Efficiency
RS18017xs+ integrates the Btrfs file system, bringing the most advanced storage technologies to meet the management needs of modern large-scale businesses:

  • Flexible Shared Folder / User Quota System provides comprehensive quota control on all user accounts and shared folders.
  • Advanced snapshot technology with customizable backup schedule allows up to 1,024 copies of shared folder backups and 65,000 copies of system-wide snapshots without occupying huge storage capacity and system resources.
  • File or folder level data restoration brings huge convenience and saves time for users who wish to restore only a specific file or folder.
  • File self-healing: Btrfs file system is able to auto-detect corrupted files with mirrored metadata, and recover broken data using the supported RAID volumes, which include RAID 1, 5, 6, and 10.

Virtualization Ready
RS18017xs+ provides seamless storage solutions for virtualization environments, including VMware, Citrix, Hyper-V, and OpenStack. With VMware vSphere 6 and VAAI integration certified, RS18017xs+ helps offload specific storage operations and optimizes computation power for unparalleled performance and efficiency in VMware environments. Windows Offloaded Data Transfer (ODX) and Synology Advanced LUN support greatly improve the efficiency of massive data transfer and migration. With OpenStack support, RS18017xs+ can be used as a block-based storage component for servers complying with the Cinder API.

Comprehensive Business Applications
Powered by the innovative Synology DiskStation Manager (DSM), RS18017xs+ comes fully-equipped with applications and features designed specifically for largescale business:

  • Windows® AD and LDAP support allow easy integration with existing business directory services without recreating user accounts.
  • Windows ACL support provides fine-grained access control and efficient privilege settings, allowing RS18017xs+ to fit seamlessly into current infrastructure.
  • MailPlus allows your business to set up a secure, reliable, and private mail server while giving your employees a modern mail client for receiving and sending messages.
  • Powerful collaboration suite that includes Synology Office, Calendar and Chat for secure and high-performance private communications and user-friendly content organization.

Reliability, Availability & Disaster Recovery
System reliability is of paramount importance to businesses which depend upon their commercial servers every day. RS18017xs+ responds to these concerns with wide-ranging availability and redundancy features:

  • Synology High Availability ensures a seamless transition between clustered servers in the event of server failure with minimal impact on applications.
  • Redundant power supplies, system fans and network ports with failover support ensure maximum continuous service uptime.
  • High-reliability system design, including fan-less CPU heatsink and passive cooling technology, prevents single points of failure.
