IOMeter is an I/O subsystem measurement and characterization tool for single and clustered systems. It is used as a benchmark and troubleshooting tool and is easily configured to replicate the behaviour of many popular applications. One commonly quoted measurement provided by the tool is IOPS.
IOMeter allows the configuration of disk parameters such as the ‘Maximum Disk Size’, ‘Starting Disk Sector’ and ‘# of Outstanding I/Os’. This allows a user to configure a test file upon which the ‘Access Specifications’ configure the I/O types to the file. Configurable items within the Access Specifications are:
- Transfer Request Size
- Percent Random/Sequential distribution.
- Percent Read/Write Distribution
- Aligned I/O’s.
- Reply Size
- TCP/IP status
- Burstiness.
With hard drives we generally don’t worry about the disk IO rate, but more the access time and we find the Gauntlet has a fairly low access time, topping out at just under 17ms.
