IOMeter
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.
Putting the read IOPs directly to the test with a fifteen minute test of pure sequential reads we find the drive topping out at just under 76k, a little short of the 86k IOPs that the 240GB SKU is rated for.
Unlike the read performance, the write IOPs in a sequential test push over the 60k rating and on to just under 67k.
