Short-depth rack storage with redundant power
The QNAP TS-873AeU-RP-4G provides eight SATA bays in a 297.4 mm-deep 2U chassis designed for compact racks and cabling-dense installations. Dual 2.5GbE, two M.2 NVMe slots, a PCIe Gen 3 x8 slot and dual power supplies support shared storage, virtual machines, multi-user access and hybrid-cloud workflows.
Key features and benefits
297.4 mm short-depth chassis
The compact depth suits smaller racks, media cabinets and installations where rear cabling space is limited.
Dual 2.5GbE networking
Two 2.5GbE RJ45 ports provide multi-gigabit connectivity and support port trunking.
Two M.2 NVMe slots
Two M.2 2280 PCIe Gen 3 x1 slots support compatible NVMe SSDs for cache acceleration.
PCIe expansion
One PCIe Gen 3 x8 slot supports compatible network, QM2 or Fibre Channel cards within the stated dimensions.
Virtual machine support
The feature set includes virtual machines and containers for running applications on the NAS.
Redundant power
Two 300W power supplies support continuity-focused rack deployments.
