Faster connection than 10Gbe Ethernet?

[lg101]

I'm currently gathering between 8 to 10 TB of data a day and I'm saving the data to a small RAID device via 10Gbe ethernet.

It needs to be saved to external RAID because it will be shipped daily.

I'd like to improve this by adding a thunderbolt 3 connection which will allow 40Gbps transfer.

I don't see an option available for this? Is there plans to provide thunderbolt 3?

Hi Ig101,

I know that there are devices available on the market that support the Thunderbolt 3 Connection.

Unfortunately this is not something available from NI and unable to comment for certain whether this is a future plan.

Kind Regards,

If you happen to be using a MXIe controller, then you could add a card to the controlling PC.

Alternately, you could also use a x8 MXI interlink to connect the system (embedded or remote controller)  to a sister computer. The sister computer would either house the RAID or at least a fast hard drive to buffer and fast transfer available from vendor of your choice.

Look at Model: PXIe-8383MC  This is an expensive option and requires PXIe. Cable length would be limited to 5m for copper or more $$ for fiber. The data throughput should be at least as high as 200 MB/s per channel with 8 channels (assumes transfer as limiting factor.)

Yes, its external connector is PCIe 2.0 x8. Keep in mind that this link has a throughput of about 4GB/s. Which is only about 3x of what a 10 GBit Ethernet link can do.

Yes, that ~3 fold difference in bandwidth spec is technically correct in a world where the expected  overhead and latency of the two technologies were equal....

I was simply bringing up a current working solution that may not have been obvious given the intricacies of the NI Website.
