flexAIserver Overview


The flexAIserver is a bare metal COTS machine that allows instantiating multiple well-known Junger Audio algorithms and other 3rd party audio processors that run on x86 processors.

Users may supply their own COTS server, or purchase pre-configured hardware from Telos Alliance together with the processing licenses to suit their needs.

Pre-configured Hardware

The pre-configured server meets all of the hardware requirements to run the flexAI software, including an available PCIe card for tieLight/MADI, an available Intel I350 Ethernet card with 4x 1GBit or 2x 10Gbit for independent redundant control network and AoIP connections, and a standard native NIC with independent 1GBit/10GBit ports for control and AoIP networks.

Customer-provided Hardware

Junger recommends hardware meeting the following specifications:

  • Intel Xeon Silver 4310 2.1GHz, 18MB cache, 12 cores, 24 threads

  • 32GB RAM

  • RAID-Controller supporting Linux Debian 10

  • 2x 480GB SSD SATA drives

  • 1x PCIe slot (full height or low profile)

  • Dual, hot-pluggable, redundant power supplies

  • Dual Ethernet NICs with IEEE 1588 and Linux Debian 10 support

  • Hardware management with openIPMI support and Linux Debian 10 compatibility

Note: There is no "plug and play" installation on customer-supplied hardware, and proper setup of the BIOS and boot settings requires detailed knowledge of the flexAI core. Accordingly, a service fee will be charged for remote installation and configuration. For most customers, Junger highly recommends purchasing pre-configured hardware from Telos Alliance.
