Synology SA3400D 12-bay NAS with Active/Passive Dual Controllers (Diskless)

The Synology SA3400D is a high-performance, enterprise-class 12-bay active-passive dual-controller NAS designed for businesses requiring robust, scalable, and reliable data storage solutions. This diskless model delivers exceptional performance with sequential read and write throughputs of up to 3,500 MB/s and 2,900 MB/s respectively, making it well-suited for handling data-intensive applications that demand high-speed access to large volumes of data. The dual-controller architecture operates in an active-passive configuration, ensuring high service availability by enabling minute-level failover in the event of a controller failure, which significantly reduces potential downtime and maintains continuous operations.

A key feature of the SA3400D is its built-in data protection solutions that enhance redundancy and reliability. The system supports expansion through the addition of two Synology RXD1219sas Expansion Units, allowing users to triple their total storage capacity and increasing the drive bay count to 36. This scalability ensures that the SA3400D can grow alongside business needs without requiring a complete system overhaul. Furthermore, the NAS is backed by a comprehensive 5-year warranty, underscoring Synology’s commitment to long-term product reliability and customer support.

Designed with efficiency in mind, the SA3400D offers a compact form factor that delivers enterprise-grade performance without occupying excessive physical space. Its raw storage capacity can reach up to 240 TB when configured with twelve drives, expanding further to 640 TB when fully expanded with additional expansion units. This makes it an ideal choice for organizations that require both file and block storage capabilities within a single appliance.

The system runs on Synology DiskStation Manager (DSM), an advanced operating system that provides comprehensive data management tools tailored for physical endpoints, virtual machines (VMs), and SaaS applications. DSM includes robust backup solutions and centralized management features that streamline administrative tasks while ensuring data integrity and accessibility across various platforms.

In summary, the Synology SA3400D represents a powerful blend of performance, scalability, and reliability tailored for enterprise environments. Its dual-controller design ensures continuous operation even during hardware failures while offering extensive expansion options to accommodate growing data demands. Whether used for centralized file storage, virtualization support, or backup management, this NAS delivers a cost-effective and efficient solution for businesses seeking dependable enterprise storage infrastructure.
