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.

Looking more precisely at the read IOPs with Iometer, after a 15 minute test run, the drive is able to give well over 90,000 IOPs making it one of the best drives we have seen.

The write IOPS as expected are a little lower, however they are still relatively high with 70,000 IOPs recorded.
