High-performance data management solution designed for business-oriented needs.
Synology RS3621RPxs is a powerful 12-bay storage server. Its 6-core processor enables compute-intensive services while its redundant power, ECC memory, and Btrfs file system safeguard mission-critical data. Capable of delivering 189,098 4K random read IOPS and 4,718 MB/s sequential read throughput1, it is ideal for small businesses.
Intel® Xeon® D-1531 6-core 2.2 GHz
4,718 MB/s seq. read 189,098 4K random read IOPS
Dual PCIe slots for 10GbE or NVMe cache
Up to 36 drive bays with RX1217(RP)
Service continuity is at the core of the RS3621RPxs design.
Redundant power
Dual PSUs provide protection against a PSU failure or accidental cord removal while hot-swappable fans allow them to be replaced without powering down the system.
Near-zero downtime
Synology High Availability (SHA) pairs two identical units together creating an active-passive cluster with minute-level failover. Learn more
Next-generation file system
Btrfs prevents data corruption and reduces maintenance overheads with advanced storage technologies and optimized snapshots.
The two built-in PCIe slots allow users to customize the RS3621RPxs to satisfy unique performance, networking, and storage requirements
Support for 10GbE NICs expands the throughput of the unit by up to 5x times using link aggregation.
Boost read/write IOPS by up to 16 times by enabling SSD cache via our Synology M.2 NVMe adapter cards and SNV3000 Series SSDs or by installing one or more 2.5 SAT5200 SSDs.
Expand to 36 drive bays using two RX1217(RP) expansion units with minimal intervention.
Keep disaster at bay
A comprehensive backup and recovery solution for securing data stored on Synology servers. Backup data locally, to another Synology device, rsync server, or cloud-based storage such as Google Drive, Dropbox, S3-compatible destinations, and Synology C2. Deduplication4, integrity checks, and incremental transfer technology reduce bandwidth and storage used.
Easily schedule flexible point-in-time backups of shared folders and iSCSI LUNs with an RPO as low as 5 minutes and recovery in seconds. Set up replication and failover to other Synology storage systems for fast RTOs and minimal service disruption.
Active Backup Suite
Enables administrators to easily backup the entire IT infrastructure to their NAS, including Windows & Linux workstations and servers, file servers, VMware and Hyper-V virtual machines, and Microsoft 365 and Google Workspace accounts. Backups benefit from deduplication, multiversioning, and optimizations to reduce bandwidth and storage used.
Synology iSCSI storage supports mainstream virtualization solutions with an easy management interface to enhance usability. VMware vSphere 6.5 and VAAI integration helps offload storage operations. Windows Offloaded Data Transfer (ODX) speeds up data transfer. OpenStack Cinder support turns your Synology NAS into a block-based storage component. Additionally, Synology Storage Console enables even more simplified storage provisioning and management options in VMware and Windows environments.
Synology Surveillance Station transforms the RS3621RPxs into a feature-packed Network Video Recorder solution. Support for up to 75 IP cameras5 and video analytics such as motion detection, no idle zone, foreign object detection, and anomaly detection cater to the most common surveillance scenarios
Engineered to handle intensive 24/7 workloads, Synology drives consistently deliver top-grade performance.
The RS3621RPxs runs Synology DiskStation Manager (DSM), the unified operating system equipped with applications and services designed specifically for businesses.
Public Cloud Integration
Back up and synchronize data easily between public cloud accounts and your NAS.
Virtual Machine Manager
Run various operating systems in isolated sandboxes. Seamlessly clone, store, and migrate virtual machines.
Synology Drive
Instantly access your NAS files across multiple devices whenever you want, wherever you are.
Central Management System
Conveniently manage your fleet of Synology NAS from a centralized console.
Security
Secure data with comprehensive built-in security tools to protect your devices against evolving threats.
Collaboration Suite
Satisfy all team collaboration needs behind the safety of your own private cloud with Synology Office, Calendar, and Chat.
At Synology, we are committed to product innovation and quality. The RS3621RPxs is backed by a 5-year limited warranty that includes technical support and hardware replacement services to maximize your return on investment
