Description

Just curious if you know whether there are any known issues with running sgpdd-survey against 2TB drives. In my testing when I get above 8 concurrent regions and 32 threads/virtual disk I start seeing errors. When I run the same test on the same server/OS configuration against an older 9550 with 250GB drives (SDR) I don't get the errors.

I have seen some output from sgpdd-survey on the web from some testing that the University of Florida did that is similar to my results (http://wiki.hpc.ufl.edu/index.php/Adaptec_51645_Performance). The common denominator is the size of the drive.

This can be a simple yes or no answer, but if you have any addition insight that you can pass along that would be appreciated as well.

Thanks.
