QNAP has introduced the TS-432XeU, a 4-bay short-depth rackmount NAS that combines 10GbE SFP+ and dual 2.5GbE networking in a 1U chassis measuring just over 292mm deep. The compact design is intended for installations where a conventional full-depth rackmount NAS may not fit, including wall-mounted network cabinets, small server rooms, factory floors, surveillance environments, and AV installations.
The TS-432XeU uses the Annapurna Labs Alpine AL324, a 64-bit ARM Cortex-A57 processor with four cores running at 1.7GHz. The AL324 is a familiar platform in QNAP’s lineup, having previously appeared in systems including the TS-832PX, TS-932PX, and TS-432PXU. The new system pairs it with 4GB of DDR4 memory, expandable to 16GB through its single SODIMM slot. Its four hot-swappable SATA bays accommodate either 3.5-inch SATA HDDs or 2.5-inch SATA SSDs.
12-Inch Short-Depth 1U Design
At 43.3 × 430 × 292.12mm, the TS-432XeU is considerably shallower than a conventional rackmount server or storage system. The roughly 12-inch chassis can be installed in compact racks and wall-mounted cabinets, with QNAP also listing factories, small offices, security monitoring rooms, media studios, and vehicle-based installations among the supported deployment environments.
The four SATA bays support 6Gb/s and 3Gb/s drives along with SSD cache acceleration. External storage expansion is available through compatible QNAP JBODs, including the 4-bay TR-004U and the 12-bay TL-R1200C-RP.
10GbE and Dual 2.5GbE Networking
Network connectivity includes one 10GbE SFP+ port and two 2.5GbE RJ45 ports. The two 2.5GbE interfaces support SMB Multichannel, allowing a compatible client to use both connections for additional bandwidth, as well as port trunking for environments serving multiple simultaneous clients. The 10GbE SFP+ interface provides a separate higher-bandwidth connection for storage traffic.
The TS-432XeU also has four USB 3.2 Gen 1 ports supporting speeds up to 5Gbps. These can be used with external HDDs and SSDs, flash drives, and compatible QNAP USB JBOD enclosures for backup, data import, cold storage, or additional capacity.
Backup, Containers, and Surveillance
In addition to file storage, the TS-432XeU supports scheduled snapshots and QNAP’s backup applications for NAS and file servers, cloud services, Mac systems, Microsoft 365, Google Workspace, and other endpoints. Rsync, FTP, and CIFS/SMB are supported for file-server backup, while the NAS can also serve as an Apple Time Machine destination. QNAP’s synchronization tools provide cross-device sync, version control, custom synchronization rules, and shared team folders.
Container Station provides Docker container support for applications, development environments, sandboxes, and microservices. The ARM-based processor should be considered when selecting container images, as applications need to support the platform’s 64-bit ARM architecture.
The TS-432XeU can also be used for surveillance, with support for ONVIF cameras, centralized video management, video backup, and server-side AI analysis. Recordings can be stored on compatible QNAP JBOD expansion enclosures or backed up to QVR Recording Vault and myQNAPcloud Surveillance.
Security and Management
The TS-432XeU supports AES-256 encryption and integrates with Windows AD, Azure AD, and LDAP. Account security options include passwordless login and two-factor authentication, while QVPN Service and QuWAN provide VPN and multi-site connectivity options.
QNAP also includes QuFirewall for IP- and region-based access controls, Security Center for monitoring NAS status and unusual file activity, Notification Center for centralized system alerts, and Malware Remover. SMB signing acceleration is supported for secured SMB file transfers.
