Synology SA6400 NAS Storage System

The SA6400 is a high-performance, highly scalable NAS designed to handle growing data storage demands with ease. Built to empower enterprises, studios, and data centers, this 12-bay chassis scales fluidly to support up to 108 drives with expansion, delivering massive capacity without sacrificing reliability or speed. It harnesses Synology’s DiskStation Manager (DSM) to provide a familiar, enterprise-grade management experience, combining robust data protection, flexible virtualization support, and efficient workflow automation. Whether you’re consolidating backups, hosting virtual machines, streaming 4K media, or powering data-intensive scientific workloads, the SA6400 is engineered to accelerate projects, simplify operations, and protect your most valuable assets. With advanced caching, security features, and a modular architecture, this storage system is designed to grow as your organization grows—the right fit for large production studios, ambitious data centers, and research workflows that demand predictable performance and unwavering reliability.

• Unmatched scalability and density: Start with 12 hot-swappable bays and scale to an extraordinary 108 drives using compatible expansion units. This architectural breadth provides vast capacity for long-term growth, while preserving a compact footprint that fits data centers and studio racks alike. The SA6400 is purpose-built for multi-petabyte ambitions, enabling you to expand storage without migrating workloads to new hardware.
• Blazing performance for multi-workflows: Engineered for demanding workloads, the SA6400 combines a powerful multi-core processor with fast memory and PCIe-enabled NVMe caching. This combination accelerates virtualization, large-scale backups, media rendering, and data analytics, delivering responsive I/O and reduced latency across concurrent users and applications.
• Enterprise-grade data protection and resilience: Protect critical data with built-in features such as snapshots, replication, and automated recovery workflows. Centralized protection across multiple volumes helps guard against accidental deletion, ransomware, and corruption, while efficient duplication and backup tools simplify disaster recovery planning and compliance.
• Smart data management and virtualization support: DSM brings a mature ecosystem of apps for backup, synchronization, and virtualization. Run virtual machines, containers, and services directly on the SA6400, manage storage pools with Storage Manager, and leverage cross-site replication to safeguard remote sites or cloud destinations—all in a single, cohesive interface.
• Flexible networking and caching for optimized throughput: Take advantage of high-speed networking options and PCIe-based NVMe caching to boost throughput and IOPS. The SA6400 supports versatile networking configurations to meet bandwidth requirements for large teams, media teams, and enterprise workloads, while caching accelerates random I/O-heavy tasks and improves overall user experience.

How to install SA6400

• Prepare your environment: Choose a suitable rack location with proper cooling and power provisioning. Verify that your network is segmented appropriately for performance and security, and ensure expansion plans are aligned with your growth roadmap.
• Unpack and mount: Install the SA6400 in a compatible rack, secure the chassis, and connect the power and network cables. If you plan to use expansion units, position and connect them according to your expansion strategy.
• Insert drives and configure: Add compatible SATA/SAS drives to the 12 drive bays. Boot the system and run Synology Assistant or connect via the browser to locate the device and start the DSM setup wizard.
• Initialize storage pools and volumes: Use Storage Manager to create storage pools and volumes, configure data protection (RAID types, protections), and set up SSD caches if you are using NVMe or SSDs for caching.
• Set up users and permissions: Create user accounts, groups, and access rights. Apply security policies, enable 2FA, and configure firewall rules or IP blocks to protect the system from unauthorized access.
• Enable protection and automation: Configure Snapshot Replication, Hyper Backup, and Offsite Replication or Cloud Sync as needed. Schedule automated backups and establish disaster recovery tests to ensure readiness.
• Integrate with services and monitors: Connect DSM with your virtualization environment, remote monitoring, and enterprise backup workflows. If needed, install additional packages from the DSM Package Center to extend capabilities across monitoring, file sharing, and collaboration.
