AMD Ryzen processing and expandable ECC-capable memory

The AMD Ryzen Embedded V1500B processor provides four cores, eight threads and a 2.2GHz clock speed. The TS-673A-8G includes 8GB SODIMM DDR4 memory and supports up to 64GB across two slots.

ECC memory is supported. The pre-installed non-ECC memory must be removed before using ECC modules because ECC and non-ECC memory cannot be installed together.

  • Use a pair of identical DDR4 modules for dual-DIMM configurations.
  • AES-NI hardware encryption is listed in the specification.
  • Optional graphics and hardware transcoding can be added through compatible PCIe hardware.

Dual 2.5GbE and flexible PCIe expansion

Two built-in 2.5GbE ports are backward compatible with 1GbE and 100MbE. The product information states that Port Trunking can provide up to 5Gbps combined transfer bandwidth.

Two PCIe Gen 3 x4 slots support compatible networking, SSD caching, additional USB connectivity, wireless networking or Fibre Channel expansion.

  • Three USB 3.2 Gen 2 Type-A ports support up to 10Gbps.
  • One USB 3.2 Gen 1 Type-C port supports up to 5Gbps.
  • Optional 5GbE and 10GbE networking can be added through compatible PCIe adapters.

M.2 NVMe caching, Qtier and storage optimisation

Two built-in M.2 2280 PCIe Gen 3 x1 slots support compatible NVMe SSDs for SSD caching and Qtier Technology. M.2 SSDs are not included.

Qtier can move data between M.2 SSDs, 2.5-inch SSDs and high-capacity hard drives according to access frequency.

  • SSD caching can improve random-access workloads and reduce latency.
  • Qtier 2.0 uses reserved SSD-tier space to respond to burst I/O.
  • Built-in M.2 slots do not support hot swapping.

The product information recommends a QNAP or third-party heatsink because M.2 SSDs can generate excessive heat.

Virtualisation plus QTS or QuTS hero

The product information lists support for virtual machines, containerised applications and GPU pass-through, with VMware Ready, Microsoft Hyper-V, Citrix and Veeam Ready certifications.

QTS and QuTS hero use different file systems. All drives must be removed before switching operating systems.

  • QuTS hero requires at least 8GB memory.
  • Inline data deduplication requires at least 16GB, with at least 32GB recommended for optimal performance.
  • An SSD RAID with at least two SSDs is recommended for the QuTS hero system drive.

Important purchasing and deployment notes

  • The product name identifies a no-disk configuration; compatible drives are purchased separately.
  • M.2 SSDs are not included and built-in M.2 slots do not support hot swapping.
  • ECC and non-ECC memory cannot be mixed, and identical modules are recommended for dual-DIMM configurations.
  • Switching between QTS and QuTS hero requires removing all drives because the operating systems use different file systems.

Frequently asked questions

What is the QNAP TS-673A-8G?

It is a diskless six-bay AMD Ryzen NAS with dual 2.5GbE, two M.2 NVMe slots, two PCIe Gen 3 x4 slots and support for QTS or QuTS hero.

Does the TS-673A-8G include storage drives?

No. The supplied product name identifies a no-disk configuration, so compatible storage drives must be purchased separately.

Which drives are supported?

The six hot-swappable bays support compatible 3.5-inch SATA hard drives and 2.5-inch SATA solid state drives.

Which processor is installed?

It uses an AMD Ryzen Embedded V1500B four-core, eight-thread processor running at 2.2GHz.

How much memory is installed and supported?

The TS-673A-8G includes 8GB DDR4 memory and supports up to 64GB using two 32GB SODIMM modules.

Does the TS-673A support ECC memory?

Yes. ECC memory is supported, but the pre-installed non-ECC memory must be removed because ECC and non-ECC memory cannot be used together.

Which network ports are built in?

It includes two 2.5GbE ports that are backward compatible with 1GbE and 100MbE.

Can the two 2.5GbE ports be combined?

Yes. The product information states that Port Trunking can provide up to 5Gbps combined transfer bandwidth.

Does it include M.2 NVMe slots?

Yes. It includes two M.2 2280 PCIe Gen 3 x1 slots. M.2 SSDs are not included and are not hot-swappable in the built-in slots.

What can be added through PCIe?

The two PCIe Gen 3 x4 slots can support compatible networking, SSD caching, additional USB, wireless networking or Fibre Channel expansion.

Can the TS-673A run QTS and QuTS hero?

Yes. Both are supported, but all drives must be removed before switching because the operating systems use different file systems.

What warranty applies to the TS-673A-8G?

This product is covered by a three-year QNAP manufacturer warranty.
