Synology RackStation RS3621RPxs SAN/NAS Storage System

Safeguard your business data with the Synology RackStation RS3621RPxs SAN/NAS Storage System. This powerful 12-bay rackmount storage server is engineered for reliability, scalability, and performance, making it ideal for small to mid-size organizations that demand nonstop operations. With a 6-core processor, ECC memory, and the hardened Btrfs file system, the RS3621RPxs delivers compute-intensive services while protecting mission-critical data. It’s designed to streamline backups, virtualization, media workflows, and large-scale file sharing, all under a single, easy-to-manage platform.

• 12-drive bays in a 2U rackmount chassis offer flexible capacity and fast expansion paths. Start with a solid base configuration and scale up as your data grows, using Synology expansion units or larger HDDs/SSDs to meet evolving business needs.
• Redundant power supply and hot-swappable components maximize uptime, helping to keep essential services online even during maintenance or drive failures. This reliability is crucial for 24/7 operations, disaster recovery rehearsals, and business continuity planning.
• 6-core processing power handles virtualization, backups, and compute-intensive workloads with ease. Pair this with Synology’s DSM software to deploy virtual machines, container workloads, and advanced data services without bottlenecks.
• ECC memory and the Btrfs file system deliver robust data integrity, end-to-end checksums, and protection against silent data corruption. Built-in snapshot and replication capabilities help you recover quickly from accidental deletions or ransomware threats.
• High performance for demanding workloads, with 189,098 4K random read IOPS and 4,718 MB/s throughput potential. This level of speed accelerates backups, large-scale file transfers, database access, and media editing workflows in a centralized storage environment.

The RS3621RPxs combines enterprise-grade reliability with flexible cloud and virtualization integration. It supports a range of protocols and services—SMB, NFS, and iSCSI for NAS and SAN needs—so you can deploy file shares for teams while presenting block storage to virtualization hosts. The platform’s efficiency is complemented by powerful storage management features, such as automatic data scrubbing, integrity checks, and advanced RAID options, all accessible through a polished, intuitive DSM interface. Whether you’re archiving large multimedia projects, running virtual machines, or consolidating backup targets, the RS3621RPxs is designed to handle it with consistency and ease.

How to Install Synology RackStation RS3621RPxs

To get your RS3621RPxs up and running quickly, follow these practical steps. Begin with a clean rack installation in a secure environment, ensuring proper ventilation and cable management to maintain airflow and ease maintenance. Once mounted, populate the drive bays with appropriate HDDs or SSDs, then connect the unit to power and your network. Power on the device and open a web browser to locate the DSM setup wizard, which will guide you through initial configuration of storage pools, volumes, and user accounts. Choose a RAID configuration that aligns with your data protection goals (for example, SHR for simplicity and efficiency or a traditional RAID set for strict performance needs). Enable essential data protection features such as Btrfs snapshots, replication, and backup tasks to protect against data loss. Finally, install required DSM applications for your needs—Virtual Machine Manager for virtualization, Synology Drive for collaboration, and File Station for secure file access—then schedule regular health checks, firmware updates, and backups to keep the system resilient over time.
