INDRA lab
- VTP
  - FPGA TCP stack being improved, however the current firmware has a limited control over TCP/IP configuration.
  - For the resource utilization studies software stream-source was used (contains real hardware payloads).
- SAMPA
  - Ed sent Vardan detailed instructions how to operate the SAMPA setup.
  - Vardan started the readout and recorded data from 5 front-end cards in 10 separate files (2 stream per card).
Data Lake
- The problem reported while increasing the depth of the data lake. Chris is working on it.
Data format
- David described the EVIO based streaming data format.
- EVIO-6 data format was proposed to use as a streaming data format, while safely ignoring the "index array" and the "user header" sections of the data-format.
- Carl will setup a meting with Hall-B to discuss if the suggested change will affect them ( note that Hall-B is not yet switched using the EVIO-6 as their off-line data format).
