Asustor Rolling Out Gen5 Rackmount NAS – The AS7212RDX and AS7216RDX Lockerstor Pro Gen2

At Computex 2025, Asustor unveils its latest additions to the Lockerstor rackmount family—the Lockerstor R Pro Gen2 series, comprising the 12-bay AS7212RDX and 16-bay AS7216RDX NAS systems. Positioned as high-performance, scalable solutions for small to medium businesses and enterprise deployments, these new models mark a notable hardware shift for the brand. Powered by AMD’s latest Ryzen 7 Pro processors and featuring support for PCIe Gen 5, 10GbE networking, and DDR5 ECC memory, this generation is clearly engineered for intensive multitasking, virtualized environments, and high-throughput applications. In addition to core hardware improvements, the systems ship with the ADM 5 software platform, which brings expanded storage and network configuration options, enhanced snapshot tools, and a wide ecosystem of applications. Combined with support for the new Xpanstor 12R expansion chassis and backed by a 5-year warranty, the Lockerstor R Pro Gen2 series is clearly being positioned to compete in the same space as rackmount solutions from QNAP, Synology, and TrueNAS, but with a focus on open upgrade paths and hardware flexibility. In this article, we break down the hardware, software, and overall direction of this release based on what we’ve seen firsthand on the Computex show floor.

Lockerstor R Pro Gen 2 Hardware Specifications

The Asustor Lockerstor R Pro Gen2 series, comprising the 12-bay AS7212RDX and the 16-bay AS7216RDX, represents a significant upgrade in rackmount NAS architecture, engineered specifically for small to medium-sized businesses and enterprise-grade environments. At the heart of both systems is the AMD Ryzen 7 Pro processor, based on a 5nm process with 8 physical cores. This processor line, typically used in high-efficiency workstations, delivers balanced compute performance and thermal control, making it suitable for multi-threaded tasks such as virtualization, container deployment, and high-volume file services. The systems ship with 16 GB of ECC DDR5 memory as standard, offering improved memory bandwidth and error correction capabilities vital to maintaining consistent data integrity under sustained load.

In terms of storage acceleration and flexibility, both units are equipped with a single M.2 NVMe slot supporting PCIe 5.0, offering a notable increase in throughput compared to earlier PCIe 3.0 or 4.0 implementations. This slot is intended for either SSD caching or as a standalone high-speed storage tier, useful for workflows involving small file I/O, databases, or active archive datasets. Both systems also feature dual 10-Gigabit Ethernet and dual 1-Gigabit Ethernet ports, enabling high-speed networking with support for link aggregation, load balancing, and network redundancy. For those requiring more, a PCIe Gen5 x8 expansion slot is available, compatible with a wide range of enterprise accessories including SAS expansion controllers or additional 25/40/100GbE NICs, offering clear upgrade paths for future network scaling.

Operational resilience is enhanced by redundant 80 PLUS Platinum-certified power supplies, designed to minimize energy waste while providing reliable failover in the event of a PSU failure. The hot-swappable nature of these components, combined with tool-less access to the drive bays and internal fan modules, supports minimal disruption during maintenance or component replacement. Both models use a standard 2U rackmount form factor and support a variety of enterprise-class SATA or SAS drives. Additionally, they are fully compatible with Asustor’s Xpanstor 12R SAS JBOD expansion unit, allowing businesses to scale storage capacity with minimal downtime. Asustor includes a 5-year hardware warranty with these units, placing them firmly in the enterprise support tier and aligning with long-term deployment cycles common in business environments.

Lockerstor R Pro Gen 2 ADM Software

ADM 5, the latest iteration of Asustor’s NAS operating system, is pre-installed on the Lockerstor R Pro Gen2 series and delivers a broad set of administrative, storage, and security features geared toward SMB and enterprise users. The interface is browser-based, with a modular design that separates key configuration areas—such as access control, storage, network, and service management—into distinct application windows. While this layout may require some initial familiarization, it provides logical compartmentalization that benefits ongoing maintenance and delegation of user privileges. On the storage side, ADM supports both Btrfs and EXT4 file systems. Storage pools—representing RAID arrays—must be mapped directly to volumes, meaning that each volume corresponds to a single RAID pool, and the OS does not currently support multiple volumes on a single pool. Snapshot functionality is implemented at the volume level rather than on a per-folder basis, which could be limiting for users seeking granular rollback capabilities. Nevertheless, snapshots can be scheduled at hourly intervals, locked to prevent automatic deletion, and restored manually or automatically, including optional pre-restore snapshot creation. The system also includes scrubbing and defragmentation tools for Btrfs volumes.

ADM 5 includes a wide range of file-sharing services, including SMB (with multichannel support), AFP, NFS, FTP, WebDAV, Rsync, and iSCSI. Each of these services can be configured through a dedicated “Services” panel, with advanced tuning options such as SMB encryption levels, access control lists, and port customization. iSCSI support includes LUN and target creation, authentication, and snapshot scheduling. The built-in File Manager allows users to open multiple file browser windows simultaneously within the same tab, streamlining operations like drag-and-drop transfers or cross-volume comparisons. Shared folders can be configured with granular access control, write-once-read-many (WORM) settings, and optional encryption. Users can also specify upload/download-only folder behavior for shared workspaces. Drive monitoring tools include support for SMART diagnostics, IronWolf Health Management (on supported Seagate drives), and drive lifespan tracking. However, NVMe SSD management features are currently limited, with no built-in benchmarking or thermal analysis tools. On the system security side, ADM Defender provides firewall configuration, IP blacklisting, and brute-force protection policies. Two-step verification, user session management, and auto-lock policies are configurable for each user account. Remote access can be managed through integrated VPN settings, EasyConnect tunneling, and port forwarding, although some tasks require navigating across multiple panels rather than a unified dashboard.

Asustor Lockerstor R Pro Gen 2 Thoughts and Verdict

Seeing the Asustor Lockerstor R Pro Gen2 series up close at Computex 2025, it’s clear that Asustor is starting to target the upper end of the SMB and mid-enterprise market with a platform that prioritizes performance, scalability, and resilience. The use of AMD’s Ryzen 7 Pro processor, DDR5 ECC memory, and support for PCIe Gen5 across both storage and expansion puts this NAS series in a position to compete directly with more established rackmount offerings. With the added flexibility of the Xpanstor 12R SAS expansion unit and redundant 80 PLUS Platinum power supplies, the platform clearly anticipates long-term deployment cycles and high-availability expectations. ADM 5, preloaded on both the 12-bay and 16-bay models, offers a wide range of file services and storage management tools. It’s not the most streamlined interface I’ve seen at the show, but its modularity does provide powerful customization if you’re willing to invest time into setup. Snapshot support, folder-level access controls, and multi-gigabit networking options all contribute to a solid enterprise feature set. While there’s still room for refinement in areas like NVMe SSD analytics and centralized configuration workflows, the ADM ecosystem is evidently maturing in pace with the hardware.

As it stands today at Computex, the Lockerstor R Pro Gen2 looks to be one of the most forward-looking rackmount solutions Asustor has released to date, and one of the most competitive solution at the show! The combination of PCIe Gen5 infrastructure, robust software support, and a competitive warranty makes this system a serious contender for IT environments seeking reliability without stepping into proprietary lock-in or over-complex licensing. Final availability and region-specific configurations are still to be confirmed, but what I’m seeing here suggests Asustor is closing the gap with its more dominant competitors in the rackmount NAS space.
