Hello Rachid, Thank you very much for your reply. In this case, the EUT is the disk drive, which is connected to SCSI Adapter through the SCSI interface. The 64-bit interface is strictly between the PC and the SCSI Adapter, and does not affect the transfer rate between Adapter and the disk drive. The only benefit of using 64-bit interface is to sustain the data rate when connected to a large number of disk drives. I would assume that as long as I am transferring data between Adapter and the disk drive at the maximum transfer rate, the type of interface between Adapter and PC (both of which are already agency approved) should not matter.

All the U320 SCSI Host Bus Adapters require 64-bit PCI slot, although they will also work in the 32-bit slot. My question is do I have to use a PC with 64-bit PCI bus for my testing (these PCs are hard to come by), or can I use a PC with 32-bit PCI bus. I will appreciate your advice in helping me decide this. Regards, Ravinder Server PCB and Flex Development Hitachi Global Storage Technologies Email: ravinder.ajm...@hgst.com
