Fast data transfer out of PXIe-8133?

[u436]

Hi,

What is the fastest way to transfer data out from the PXIe-8133? I am currently using two UDP ports for the two ethernet ports with gives a theoretical transfer rate of 2Gbit/s.

How would I transfer data out from an FPGA or PXIe to a host computer faster than that?

Cheers.

Hi u436,

Where would you ultimately like all of this data to go?  Do you want to store it on a hard drive/SSD, analyze it, display it?  The fastest way to acquire data is to store it to a RAID array over a MXI-Express card.  This can be done at consistent speeds of 750 MB/s.  See the following link for details.

Hi Brian,

Thanks for the reply. My DAC is acquiring data at 8GHz. After processing on the FPGA, I have approximate 6GHz of data in real time. I don't want to store or display it. I want to send it to a (or several) computers to use the data as inputs.

Cheers.

Hi u436,

The only faster way to transfer data to a computer would be with a x4 or x16 MXI-Express Remote Controller, which would provide up to 838 MB/s or 5.6 GB/s respectively.  These would need to be installed in place of your PXIe-8133  and be controlled by the MXI card on your PC.  Also note that the x16 MXI-Express card is not supported by all PCs; it requires full PCI Express 2.0 clocking specs. 

NI PXIe-PCIe8375

NI PXIe-PCIe8388 and NI PXIe-PCIe8389

Other than that I am not aware of a faster way of exporting data to a PC(s) in real time.  Hope this helps!
