Is SQLIOsim an older tool? Is SQLIOStress a newer tool? I want to stress test a SQL 2012 environment which is a VM environment.
Also, other than HammerDB, is there another TPC-C tool which is a freeware?
Any other ideas/tools for SQL Server bench mark testing?
I am trying to test one of our environment which is pre-production and is a clustered environment and hooked up to SAN which is RAID-DP.
The following are the statements I am trying to run and it errors out saying there is not enough space on the drive even though it has about a TB free.
This is what I have in params.txt
L:\sqlIO\testfile.dat 2 0x0 100
This is what I have in the batch file which contains the sqlio command
sqlio -kW -t16 -s180 -dl -o8 -frandom -b16 -BH -LS Testfile.dat
Error is:
do_ovlp_io: WriteFileEx: There is not enough space on disk.
file offset high: 0x00000493 low: 0x3a54c000
As you can see even though I say 100MB file, it creates a test file for 3.5 GB or something and finally fails saying there is not enough disk space when the L drive contains about 935GB free.
Any ideas?

SQLIO (and IOMeter) just test the raw capabilities of the IO subsystem
SQLIOSim tests SQL Server IO patterns and requirements
For benchmarking, try this: http://qa.sqlservercentral.com/blogs/technobabble-by-klee-from-kleegeek/2013/07/29/benchmark-your-sql-server-instance-with-dvdstore/. I also think Joe Chang has some benchmarking stuff you can download on http://www.qdpma.com/
