Hello,
I want to test the max. iSCSI SAN IO-performance of my DSS. I'm a Windows user, no Linux knowledge ... What Windows tool (for Win 2008 64bit, preferred freeware) do you recommend?
regards,
Lukas

G'day Lukas,
We use two methods. For quick tests, a 1GB ISO file, Xcopy and the "Timeit" resource kit utility. And for involved Tests, Intel's NAS Toolkit.
Dear Lukasz,
You also can use IO Meter. Its a free tool that most testers use.

I second the iometer recommendation. It is the defacto testing tool in the storage community
Additional information:
If you are running Windows try using the Intel NAS Perf tester for involved tests:
http://www.intel.com/design/servers/...rf_Toolkit.htm
If you want to test your GB Network, take a look at netspeed.exe
from OptimumX http://www.optimumx.com/download/ (Assuming you have
another Windows Box to test against.)
For quick tests, a 1GB ISO file, Xcopy and the "Timeit (http://www.microsoft.com/downloads/details.aspx?familyid=9d467a69-57ff-4ae7-96ee-b18c4790cffd&displaylang=en)" resource kit utility.
OK, thanx all for replies, I downloaded IOMeter. But: What testing parameter to you recommend (Read/Write/Random/Sequentiell/Workers/outstanding IOs/Blocksize ...)??
I played around with e.g. 32K 100% seq. read and up to 256 outstanding IOs to saturate the GB-LAN and I received about 100-110 MB/s on 1 GB-Link, up to 230 MB on 2 MPIO-Links (Round-Robin). But I don't know to compare these results with other DSS installations ... (good/bad performance, bottlenecks, ...)?
Can anyone publish his testing profil (IOMeter config file)?
Lukas
Try with IOMETER 8KB block size, 65% read and 50% random configuration.
