Problem with Miniport

OSR_Community_UserOSR_Community_User Member Posts: 110,217
Hi,
I am developing a SCSI Miniport driver for Windows (9x, NT and 2000) for our
raid card. Right now I am facing a strange problem. I am using IOMeter for
our performance numbers. After a while the IOMeter is freezing (my driver
is still receiving commands and completing them successfully). The whole
system is also not fully responding. As my driver has internal queuing, my
driver has average of 10 commands always pending.

Did anyone face the similar problems? Any help will be greatly appreciated.

Thanks.

Syam.

    We've never tested using IOMeter. Whose product is it?

    Our 9x, nt4, and 2000 miniport also has an internal queue of 32. There's
    been no problem with it.

    IoMeter is an Intel I/O benchmarking tool, available for
    free download. The tool is pretty good at providing a
    standardized load on the system. You can get more data at:

    Hi,

    The IOMeter is a benchmark software from Intel to test the performance of
    the Drives (including overall CPU Utilization).
