We are moving the office uplinks from copper to fibre and the quote that came back has DrayTek-branded optics in every line. Before I start arguing about the difference against ordinary 10G modules I would like to know whether the hardware actually cares what sits in the cage, because the…
We took over a pair of ZS3-2 controllers together with the shelves behind them, and I am the one who has to order optics before they go back into service. The controller service manual is very short on this point: it lists the NIC and HBA options, and for the 10GbE SFP+ card it names exactly two…
