Powerful Storage Solution with Ample Upgradability
Equipped with an Intel Xeon D-1541 8-core CPU, 8GB DDR4 ECC UDIMM, and 16 x 3.5" drive bays in a 3U form factor , Synology RS4017xs+ is the ideal companion for intensive data processing, video post-productions, and virtualization applications that increasingly require more storage space.
RS4017xs+ 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, RS4017xs+ provides ultra-high sequential throughput at over 4,900 MB/s and 690,000 sequential IOPS .
System memory and storage capacity of RS4017xs+ can be further extended. Up to 64GB of DDR4 ECC UDIMM can be installed to support multiple virtualization instances, and with two Synology RX1217/RX1217RP2 expansion units connected, a combined total of 40 drive bays can be freely arranged for storage management.
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
RS4017xs+ 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.
RS4017xs+ provides seamless storage solutions for virtualization environments, including VMware, Citrix, Hyper-V, and OpenStack. With VMware vSphere 6 and VAAI integration certified, RS4017xs+ 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 improves the efficiency on massive data transfer and migration. With OpenStack support, RS4017xs+ can be used as a block-based storage component for servers complying with the Cinder API.
