Ryzen processing and expandable ECC-capable memory
The AMD Ryzen Embedded V1500B provides four cores, eight threads and a 2.2GHz clock speed for resource-demanding NAS applications.
The system includes 4GB SODIMM DDR4 memory and supports up to 64GB using two 32GB modules. ECC memory is supported, and dual-DIMM configurations require a matched pair.
- 64-bit x86 architecture with AES-NI encryption support.
- Optional hardware-accelerated transcoding is available through a compatible PCIe graphics card.
- Use compatible memory modules with identical specifications in a dual-DIMM configuration.
Eight SATA bays and dual M.2 NVMe slots
Eight 3.5-inch SATA 6Gb/s and 3Gb/s bays support compatible 3.5-inch hard drives and 2.5-inch solid state drives.
Two M.2 2280 PCIe Gen 3 x1 slots support compatible NVMe SSDs for SSD cache acceleration and Qtier storage optimisation.
- The system is supplied without hard drives.
- The main drive bays are hot-swappable; M.2 SSDs are not hot-swappable.
- M.2 slots are compatible with NVMe SSDs using PCIe Gen 3 and above.
Dual 2.5GbE, 10Gbps USB and PCIe expansion
Two 2.5GbE ports support 2.5G, 1G, 100M and 10M connections. Port trunking can provide transfer speeds up to 5Gbps.
One PCIe Gen 3 x8 slot supports compatible 10/25GbE networking, QM2, Fibre Channel or graphics expansion cards.
- Four USB 3.2 Gen 2 ports provide up to 10Gbps connectivity: two Type-A and two Type-C.
- Wake on LAN is supported through the 2.5GbE port, and Jumbo Frame support is included.
- HDMI output is optional through a compatible PCIe graphics card.
Short-depth deployment and operating-system flexibility
The 2U chassis measures 88.6 × 432 × 297.4mm, excluding the ear hook and protruding part of the power supply.
The TS-873AeU supports QTS or QuTS hero, allowing deployment according to operational, storage and data-protection requirements.
- The supplied information identifies smaller racks, wall-mount AV cabinets, network cabinets and surveillance recording environments as deployment examples.
- The source states that the short-depth design provides up to a 38% size reduction compared with the previous generation.
- A 250W power supply is specified.
Important purchasing and deployment notes
- This is a diskless system; compatible storage drives must be purchased separately.
- M.2 NVMe SSDs are not hot-swappable.
- For two memory modules, use a matched pair of compatible DDR4 modules.
- Confirm rack, rail, drive, memory and expansion-card compatibility before deployment.
