Does anyone know where I can find the Iometer test files used in Tom's reviews?

Many Thanks

Dude, a simple google search would've pointed out iometer.org. :p

Thanks, but I wasn't very clear......

I'm already using Iometer, but I wanted the configuration that Tom's uses in it reviews like 'workstation test' Web server test' etc.

The IOmeter patterns are very simple, you can make one yourself with IOmeter, like 4 lines or so. Googling on these should give you the workstation/server/desktop patterns.

With Intel iPeak/Rankdisk you can trace and replay complicated patterns on your RAID, so that would give you a better and more realistic score, because its based on real application traces instead of guessed static patterns.

Thanks Mesa but I googled randisk and all that comes up is reviews using randisk or ramdisks. Searched on Intels site and could not find it either! Does anyone have a link?

Not randisk, but Rankdisk. Its part of the Intel iPeak storage benchmark suite. Its not free software, however.

Agree it would be nice to see something more definitive from THG on the test methodology. Sans that, and assuming THG follows many in using the patterns from Intel and defined by Storage Review...

1. File server, Workstation, Database patterns:
http://www.storagereview.com/articles/200003/20000313OS...

2. Web Server pattern:
http://www.storagereview.com/Testbed3.sr?page=0%2C7

3. Also see:
http://www.storagereview.com/Testbed4.sr?page=0%2C5

From the IOMeter User's Guide (assuming this is what THG is doing)...

4. Max MB/sec read/write; for read:
"For maximum throughput (Megabytes per second), try changing the Transfer Request Size to 64K, the Percent Read/Write Distribution to 100% Read, and the Percent Random/Sequential Distribution to 100% Sequential."

5. Max IOPs read/write; for read:
"For the maximum I/O rate (I/O operations per second), try changing the Transfer Request Size to 512 bytes, the Percent Read/Write Distribution to 100% Read, and the Percent Random/Sequential Distribution to 100% Sequential."

6. What isn't known about THG's tests:
a) Physical drive or file used?
- If physical, what was the maximum sector (if any)?
- If a file, how big?
b) How many workers were used?
c) The warm-up/ramp and test duration?

Hope that helps.
