High-performance data management solution designed for business-oriented needs.Safeguard your business assetsSynology 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 throughput, it is ideal for small businesses.ComputeIntel Xeon D-1531 6-core 2.2 GHzThroughput4,718 MB/s seq. read 189,098 4K random read IOPSExpandabilityDual PCIe slots for 10GbE or NVMe cacheScalabilityUp to 36 drive bays with RX1217(RP)Reliability firstService continuity is at the core of the RS3621RPxs design.Redundant powerDual PSUs provide protection against a PSU failure or accidental cord removal while hot-swappable fans can be replaced without powering down the system.Near-zero downtimeSynology High Availability (SHA) pairs two identical units together creating an active-passive cluster with minute-level failover.Next-generation file systemBtrfs prevents data corruption and reduces maintenance overheads with advanced storage technologies and optimized snapshots.Customize to suitThe two built-in PCIe slots allow users to customize the RS3621RPxs to satisfy unique performance, networking, and storage requirements.10GbE readySupport for 10GbE NICs expands the throughput of the unit by up to 5x times using link aggregation.SSD cacheBoost 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.On-demand drive baysExpand to 36 drive bays using two RX1217(RP) expansion units with minimal intervention.License-free backup solutionsKeep disaster at bayHyper BackupA 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.Snapshot ReplicationEasily 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.Backup your entire IT infrastructureActive Backup SuiteEnables 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.Storage for virtualizationSynology 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.Powerful built-in surveillance functionalitySynology 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.Secure and privateAES-256 encryption keeps locally-stored footage secure.Access from anywhere, anytimeAccess recordings and live streams whenever you want using a web browser, desktop client, or the DS cam mobile app.Real-time alertsEmail, SMS, or push notifications alert you when incidents occur or predefined conditions are met.Works best with Synology drivesEngineered to handle intensive 24/7 workloads, Synology drives consistently deliver top-grade performance.• SATA 3.5" HDD HAT5300• NVMe M.2 SSD SNV3000• SATA 2.5" SSD SAT5200Powered by Synology DiskStation ManagerThe RS3621RPxs runs Synology DiskStation Manager (DSM), the web-based operating system with applications and services designed specifically for businesses.Central Management SystemConveniently manage your fleet of Synology NAS from a centralized console.Synology DriveInstantly access your NAS files across multiple devices whenever you want, wherever you are.Collaboration SuiteSatisfy all team collaboration needs behind the safety of your own private cloud with Synology Office, Calendar, and Chat.Virtual Machine ManagerRun various operating systems in isolated sandboxes.
