Hardware requirements

The following is a guide to the hardware requirements for the CAIMAN-ASR server.

Host requirements

The CAIMAN-ASR server requires a host machine with the following specifications:

  • Four CPU cores per VectorPath card
  • 4 GB of memory per VectorPath card
  • 100 GB of storage
  • Ubuntu 22.04 LTS (recommended)


The server requies 500 Mbits/s of bandwidth per 1000 streams. For example, 2000 streams would require 1 Gbit/s of bandwidth. The bandwidth is dependent on the number of streams and not the number of cards (one card can handle 2000 streams with the base model or 800 streams with the large model). This figure has some headroom built in; the measured value on a reliable connection is 700 Mbits/s for 2000 streams.
