High-speed networking and SSD acceleration
Two 10GbE SFP+ ports support intensive file access, large backup and restoration tasks, and media transfers. Two additional 2.5GbE ports support 2.5G, 1G and 100M network speeds.
- Port Trunking can combine the two 2.5GbE ports for supplied transfer speeds up to 5Gbps.
- Two M.2 2280 PCIe Gen 3 x1 slots support compatible NVMe SSDs for cache acceleration or SSD storage pools.
- Wake on LAN and Jumbo Frame support are listed in the supplied specifications.
Compact 1U short-depth rackmount design
The chassis measures 43.3 × 430 × 292.12mm, excluding the ear hook and the protruding part of the power supply unit. Its short depth provides more flexibility in smaller racks and cabling-dense installations.
- The supplied deployment examples include offices, audiovisual rooms and security surveillance recording environments.
- The optional RAIL-S01 short rail kit is identified for installation in a 19-inch rack following the ANSI/EIA-RS-310-D standard.
- Three 40mm cooling fans and a 100W power supply are specified.
Quad-core processing and expandable memory
A Marvell OCTEON TX2 CN9130/CN9131 series ARMv8 Cortex-A72 four-core 2.2GHz processor supports the supplied storage and application workloads. The system includes 4GB SODIMM DDR4 memory and supports up to 32GB.
- ECC memory is supported from the stated QTS firmware version, but installing ECC requires removal of the pre-installed memory.
- The supplied specifications list a 64-bit ARM architecture and an encryption engine.
- Maximum concurrent CIFS connections are listed as 1,500 with maximum memory installed.
Business applications and storage expansion
The supplied product information describes containerised applications, QVR Elite surveillance and storage expansion through compatible QNAP expansion units.
- Host multiple containerised applications and services.
- Use QVR Elite as the supplied subscription-based surveillance option.
- Expand storage by connecting compatible QNAP expansion units.
Important compatibility and performance notes
- The supplied source does not state that hard drives are included, so no diskless claim has been added.
- M.2 SSDs are not hot-swappable, and NVMe SSD compatibility should be checked before purchase.
- Installing ECC memory requires removal of the pre-installed memory module.
- The supplied SMB-signing benchmark figures were measured on other QNAP NAS models, so those numeric results are not presented as TS-435XeU performance.
