how to install Synology RackStation RS3621XS+ SAN/NAS Storage System

Installing the RS3621XS+ is a straightforward process that can be completed by IT staff with basic rack-mount and drive-handling experience. Begin by planning the rack placement to ensure adequate ventilation and cable management, and gather the necessary rails, mounting hardware, and drive trays. Install the 12 hot-swappable drive bays with compatible SATA drives, taking care to align drives securely in their sleds. Mount the RS3621XS+ into the rack using the provided rails, secure the chassis, and connect the power supply. Route network cables to the switch or router, ensuring clean, labeled cabling for easy future maintenance. Power on the unit and use Synology Assistant or DSM Web Assistant to locate the device on your network. Open a browser and follow the on-screen setup wizard to install the latest DSM version, configure storage pools and volumes, and create shared folders with appropriate access permissions. Enable iSCSI targets or NAS protocols (SMB, NFS, or AFP as needed) to support your clients and virtualization environments. Set up backups, snapshots, and replication to protect data across your site and remote locations. Finally, implement security best practices—enable firewall rules, disable unused services, configure two-factor authentication, and apply regular DSM updates to maintain a secure, resilient storage infrastructure.
