Compulab has announced its Airtop3 device that comes with up to an Intel Core i9-9900K CPU and Nvidia Quadro RTX 4000 graphics card. The ruggedized IoT edge server is passively cooled and has been designed for industrial use. Numerous customization options are available for the Airtop3 PC, including extended and industrial operating temperature ranges.

The rugged Airtop3 has been revealed by the Israeli manufacturer Compulab. The fanless device relies on passive cooling for its high-end components, which can be configured right up to a 9th Gen Coffee Lake SoC. However, for those who don’t require an 8-core device, the much cheaper dual-core Celeron G4900 can be selected as CPU.

If a potential Airtop3 user wants a discrete graphics card too, then Compulab has it covered. For an additional US$1,204 an Nvidia Quadro RTX 4000 8 GB solution can be installed. RAM options range from none installed all the way to 4x 32 GB, while there is also a huge choice of SSDs and HDDs to select from for the barebone PC. A Wi-Fi and Bluetooth adapter can be fitted at extra cost and there is even room for a FACE (Function And Connectivity Extension) module to be added.

Compulab claims the Airtop3 can “passively dissipate up to 300 W”, and the sturdy device also comes with five years warranty. The regular build can operate from 0 °C to 45 °C, but if you purchase the industrial option this range increases to -40 °C to 70 °C. A clamshell-type construction allows tool-free entry to the Airtop3 for swapping out or upgrading components.

The base barebone model of the Airtop3, without RAM and with a Celeron CPU, costs from US$1,018. However, if you want to start adding an 8-core Intel chip, RTX graphics, up to 128 GB RAM, up to six storage devices and all the other bells and whistles, it’s possible to configure an Airtop3 that costs around US$7,000. Either Linux or Windows 10 can be used as the operating system.

Compulab Airtop3 is bringing performance to the edge

Yokneam, Israel 23-Apr-2019 - Compulab is introducing Airtop3 - a ruggedized small-form-factor fanlessIoT edge server powered by an 8-core Intel® Core™ i9-9900K Processor and NvidiaQuadro RTX 4000, both passively cooled using Compulab’s Natural Airflow technology. With a footprint of just 7.5 liters, Airtop3 can passively dissipate up to 300W and operate at a wide temperature range of -40°C to 70°C. Airtop3 ships with a 5 year warranty.

Fanless Core i9 9900K and Quadro RTX 4000

IoT edge server can reduce processing latency, network bandwidth requirements and TCO, provided that it is sufficiently powerful, robust and easy to deploy.

Airtop3 presents a unique value proposition for edge computing in harsh environments:

·         Exceptionally high performance - 8-core, up to 5 GHz Intel Core™ i9-9900K or Intel Xeon coupled with NvidiaQuadro RTX or GeForce GTX GPU and high RAM capacity up to 128 GB

·         Rich storage, networking and I/O, each can be enhanced thanks to Airtop3’s modular design

·         Passive cooling across wide temperature range and a rugged all-aluminium small-form-factor housing

·         Maintenance-free design, tool-free serviceability and advanced monitoring and diagnostics provisions

“Apparently, the appetite for performance at the IoT edge knows no boundaries” said Irad Stavi, Chief product officer at Compulab. “We are seeing remarkable performance gains in the latest generation of CPUs and GPUs, but with great power comes greater power consumption. However, our engineers were able to improve the thermal headroom of Airtop3’s Natural Airflow cooling by over 30% so there was no need to settle for low power chips. This makes Airtop3 a small-form-factor fanlessIoT edge server with unprecedented performance.”

“Benchmarks indicate that Airtop3 is nearly twice as powerful as Airtop2" said Yuval Sela, Airtop hardware architect. "To achieve that, power delivery in Airtop3 is completely revamped and can now support the most powerful Intel 9th generation Core CPUs and even 160W NVIDIA RTX GPU."

Airtop3 performance and features

Airtop3 supports 9th Generation Intel® Core™ i9 Processors and future Intel® Xeon® E Processors, including the highest power 95W Core i9-9900K. The maximum RAM capacity is 128 GB DDR4-2666. Standard storage is comprised of 6 devices - two NVMe SSDs - up to 2 TB each and four 2.5” SATA 3 HDD/SSD with RAID support. Standard networking includes two GbE ports and support for Wi-Fi 802.11ac and 4G modem.

Standard I/O includes 3 4K displays, 6 USB 3.1 ports, 3 RS232 and audio. This feature set may be satisfactory in some cases, but IoT has many specialized applications - deep learning may require a discrete GPU, automotive applications often require high capacity of high-speed storage, machine vision usually utilizes integrated PoE ports.
For these use cases and other, Airtop3 offers functional enhancements.

Enhanced graphics

Airtop3 has a PCIe x16 (PEG) slot with Natural Airflow passive cooling that supports up to 160W Quadro RTX 4000 graphics card. This powerful CPU + GPU setup is effective for low latency edge analytics workloads involving image recognition, machine learning or inferencing.

The four displays of the graphics card can work in tandem with the integrated graphics for a total of seven 4K displays.

Enhanced storage

The standard two NVMe cards and four 2.5” SATA SSD/HDD support up to 20 GB with RST or software RAID and are passively cooled in a dedicated thermal zone.

Storage can be enhanced using Airtop3's NVM3 card installed in the PEG slot. NVM3 supports additional three NVMe cards up to NF1 30110 form factor.

NVM3 enables remarkable data rate of over 9500 MBps and increases max storage capacity to over 60 TB. It allows installing SSDs with power loss protection (PLP).

Enhanced networking

Dual Gbit Ethernet (Intel i210 + Intel i219) and optional WiFi 802.11ac + 4G/LTE modem are available as a standard. For higher bandwidth, dual 10 GbE card can be installed in the PEG slot. Extra networking capabilities can be added using a FACE Module

FM-LAN adds 4 independent GbE ports - useful for routing applications

FM-PoE adds 4 GbE ports, each with 802.3af PoE source which simplifies setups involving IP cameras

FM-OPLN adds 2 GbE SFP+ optical LAN ports which enables longer range, better immunity and higher security


Cooling, durability, modularity and monitoring

Airtop3 cooling is based on Compulab’s Natural Airflow technology that stimulates airflow without moving parts - by the waste heat of the 3 major heat sources (CPU, GPU and storage devices) each having a dedicated thermal zone.

The 7.5 liter housing is all-aluminium made of die-cast and extruded parts with precision machining for seamless fit, shock and vibration resistance.

Airtop3 supports Compulab FACE Modules (Function And Connectivity Extension Modules) which enable various application specific networking and I/O capabilities. A new FACE Module designed specifically for Airtop3 - FM-AT3 adds 2x USB 3.1 gen 2 (one USB type-C) + 1x USB 3.1 gen 1, front audio jacks, mini-PCIe socket with SIM card, micro-SD and diagnostics LEDs for troubleshooting RAM, BIOS and display issues.
