Hi Alfredo
That sounds a little bit like a challenge.
There is no "nBox Recorder" for 100Gbps?

Marcel

Hi Marcel
there are a few options, for n2disk we recommend Napatech or Fiberblaze as they support native bulk PCAP mode.
As of the storage, you can use n2disk to write to multiple NVMe disks in parallel (I do not have a specific model to recommend) or you can use SAS HDDs with 2-3 Raid controllers (each controller is usually able to write up to 35-45Gbps).
Regards
Alfredo
