Sergey, The PXI-8210 can connect to any SCSI 2 compliant device. If the RAID controller is SCSI 2 and appears just like a hard drive in the operating system, then you can send data directly to the RAID array. The problem is that the driver for the PXI-5112 does not yet support continuous acquisition. The on-board 16MB or 32MB buffer stores the data until the entire acquisition is completed. Once the acquisition complete, all of the data is transferred from the on-board buffer to the hard drive. After that happens, the NI 5112 is ready for another acquisition.
