Default Re: What is the NVRAID stripe size?

Hi:

I (re)found the NVRAID users guide but v1.1 is for Microsoft. There is no help in it for Linux. I have not found a version that has Linux info in it. So, Help, please!

There are READ issues with large files and I cannot determine what/why unless I can get some input from documentation or something else.

Specifically, when READing large files of 4GB or 8GB, I get huge loss of transfer rates(like dropping from > 100MB/s to 20-25MB/s) for record sizes that are equal to or larger than 128kB. (using self-compiled iozone to test fs)
It appears to be independent of filesystem as both ext3 and JFS exhibit the same problem.

It could be NVRAID ...or the setup/config ...or something else. I need to determine what.
