• which fibers should be MPO vs LC?
  • only use MPO for fim's.
• should we fanout timing at SRCF or put it through the bos? (related question: should camlink devices go through the bos?)
  • use the fanouts at SRCF for simplicity
  • don't maybe put camlink fiber through the bos for now?
• routing mono-encoder udp network over to srcf
• sharing xtcav between hutches with bos-switchable timing

100kHz data volumes:-

• wave8: 8waveforms*256samples/sample*2bytes/sample*0.1MHz = 400MB/s

...

• (need to add FEX data too)

...

• piranha: 2048px*2bytes/px*0.1MHz=410MB/s

...

• hsd full wf: 60000samples*2bytes/sample*0.1MHz = 12GB/s

  ...

  • • max waveform length appears to be ~60000 samples looking at xtc2 file?

  ...

  • • FEX needs to reduce it to 4GB/s (3x)

  ...

  • bld: 336bytes/event*0.1MHz = 33MB/

  ...

  • s (from xtcreader -f /cds/data/psdm/prj/public01/xtc/tmoc00118-r0222-s008-c000.xtc2)

  ...

  • timing: 309bytes/event*0.1MHz = 31MB/s

  recabling proposal:

  • tmo timing (including pvadet, bld) (LC to fanout)
  • rix timing (LC to fanout)
  • (4) tmo camlink nodes (LC)
  • (2) rix camlink nodes (LC)
  • tmo/rix fim node (5 fims) (MPO)
  • (2) rix hsd nodes (LC)
  • (7) tmo hsd nodes (LC)
  • peppex hsd node (LC)
  • (2) tmo/rix ami
  • (2) tmo/rix teb
  • (2) tmo/rix mebuser
  • xtcav
  • mono-encoder
