BUFFALO TeraStation 3430RN: 4-Bay Rackmount NAS with 32TB, 2.5GbE and iSCSI

The Buffalo TeraStation 3430RN is a high-performance, rackmount NAS engineered for small to midsize businesses that demand reliable storage, robust data protection, and fast network connectivity. With a turnkey 32TB capacity (4 x 8TB HDD included) across four hot-swappable bays, this 2U rackmount NAS consolidates file sharing, backups, virtualization-ready iSCSI, and secure remote access in a single, easy-to-manage appliance. Built to handle 40–50 concurrent users, the 3430RN blends enterprise-grade resilience with user-friendly setup, making it a practical backbone for small IT environments that require uptime, scalability, and straightforward administration. The result is a centralized storage solution that accelerates collaboration, simplifies data protection, and supports growth without complicating your network.

• Performance-driven network connectivity: Equipped with dual 2.5GbE Ethernet ports, the TeraStation 3430RN delivers substantial bandwidth for multi-user workflows, large file transfers, and media streaming. The built-in support for link aggregation enables even higher throughput, ensuring smooth backups, rapid restores, and responsive access to shared folders across Windows, macOS, and Linux clients. This creates a resilient storage backbone for departments that rely on fast, dependable network storage.
• Flexible, scalable storage with robust data protection: The 4-bay chassis supports a range of RAID configurations (0, 1, 5, 6, 10) so you can tailor safety and capacity to your needs. The 32TB total capacity comes pre-installed as four 8TB drives, removing the guesswork from setup. When you’re ready to expand, you can swap or add drives with minimal downtime, preserving your data while you scale storage to accommodate more users, larger datasets, or longer retention windows.
• Advanced data protection and privacy: Beyond RAID, the TeraStation 3430RN includes features designed to protect against data loss and unauthorized access. Expect scheduled backups, secure access controls, and encryption options to safeguard sensitive information. The device also supports iSCSI targets for virtualization and centralized storage, enabling consistent data protection policies across your hypervisor and backup workflows, while helping you maintain regulatory compliance and business continuity.
• Comprehensive management and ease of use: A web-based management interface provides intuitive setup, monitoring, and day-to-day administration for IT staff. The 3430RN is designed to minimize complexity while delivering strong performance, from initial RAID configuration to ongoing health checks, user permissions, and share management. Its modular, rackmount form factor fits neatly into existing data center or IT closet environments, making deployment straightforward for teams responsible for SMB storage infrastructure.
• Broad compatibility and government-ready reliability: The system supports standard SMB/AFP/NFS file sharing for cross-platform collaboration, and iSCSI for virtualization workloads. As a TAA-compliant device, the 3430RN aligns with procurement requirements in government and regulated sectors, ensuring it’s a capable choice for organizations that demand both performance and compliance in a single package.

How to install BUFFALO TeraStation 3430RN

• Unpack the unit and verify all components are present, including the 4 x 8TB drives in the bays. Position the 2U rackmount correctly in your equipment rack and secure it with rails or cage nuts as appropriate.
• Connect the 3430RN to your network using the included Ethernet cables. Attach a power cord and power on the device to begin the initial boot sequence.
• Discover the NAS on your network using the Buffalo setup utility or your DHCP server's client list, then open the web-based management interface in a supported browser.
• Initialize the drives and configure the RAID level of your choice (0, 1, 5, 6, or 10). If you are migrating from another NAS, you can plan your storage pools to preserve data integrity during the transition.
• Create user accounts and set permissions for Windows, macOS, and Linux clients. Set up shared folders with appropriate access controls to optimize collaboration while safeguarding sensitive data.
• Enable and configure iSCSI targets if virtualization or dedicated backup storage is part of your workflow. This allows your hypervisor hosts to connect to the NAS as centralized storage for VMs and applications.
• Set up scheduled backups, snapshots (where available), and data protection policies to ensure automatic protection against data loss. Consider cloud backup or remote replication as an additional layer of resilience.
• Apply the latest firmware and security updates through the web UI, then test connectivity by accessing shared folders from multiple clients to confirm performance and reliability across the network.
• Document your configuration for disaster recovery planning and train IT staff or end-users on best practices for data access, backups, and security;
• Regularly monitor system health, drive status, and network performance from the management dashboard to preempt issues before they affect end users.
