Compulab Airtop3 brings performance to the edge

“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 fanless IoT edge server with unprecedented performance.”

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.

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

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.

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.

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. As Airtop3 is fanless and therefore eliminates aging of the product, which allows an unconditional warranty for 5 years.

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.
