IOMeter v2006.07.27 – IOps
Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. It was originally developed by the Intel Corporation and announced at the Intel Developers Forum (IDF) on February 17, 1998 – since then it got wide spread within the industry.
Meanwhile Intel has discontinued to work on Iometer and it was given to the Open Source Development Lab (OSDL). In November 2001, a project was registered at SourceForge.net and an initial drop was provided. Since the relaunch in February 2003, the project is driven by an international group of individuals who are continuesly improving, porting and extend the product.
While the new SandForce controller sees a slight reduction in response time at Queue Depths of 2 and below, it picks up steam very quickly, cruising past everything by QD=8. 30,000 IOPS in our Web Server test is nothing to sneeze at for sure. It’s nice to see a SATA unit finally unseat the X25-M, but keep in mind that your OS and SSD operate in the QD=1-4 range for the vast majority of your uptime.
