Pertinent, Empirical Disk and Application I/O Performance Metrics

Historically, the analysis of storage I/O performance has often entailed numerous numbers, piles of plots, ballpark benchmarks – and perhaps a laborious individual I/O operation trace to decipher and review.

hyperI/O takes a different approach.  We provide "Top-Down" I/O performance metrics that:

  • Are simple and quick to obtain, including automatically-summarized even in real-time as well as exported to a file

  • Are easy to understand and use

  • Reflect how you actually use your storage


Longitudinal Synopsis



A single snapshot of a I/O workload can be revealing.  But is it representative?

Observing workload I/O operation activity over an extended period of time provides a broader understanding of overall workload I/O characteristics.

hIOmon can collect key I/O activity and performance metrics aggregated upon a weekly, monthly, quarterly, and/or yearly basis.  These metrics include I/O operation counts, data transfer amounts, queue depths, response time and much more.

And hIOmon can provide and display these key metrics within a synopsis format.


The hyperI/O Approach to Storage I/O Performance Analysis


Simple, Quick, and Easy  –  plus Private, Secure, and Cost-Effective Too!


The hIOmon software tools from hyperI/O have been designed and implemented to be simple, quick, and easy to install and use.  Plus they are secure (digitally code-signed) and they maintain your privacy (e.g., no collected metrics are transferred to hyperI/O for summarization or analysis).

Emphasizing a big-picture top-down approach, these tools enable you to easily and quickly evaluate your specific storage I/O performance.  For example, the hIOmon DXTI metric provides a fundamental measure of your storage performance efficiency much like the “fuel economy (MPG)” indicator does for automobiles.

Likewise, the hIOmon “Performance Threshold Range Metrics” enable you to capture the specific “I/O Profiles” of your particular devices, files, and applications/workloads – moreover, during normal everyday usage with no file, file system, device, or operating systems changes required.

Both real-time and historical displays allow you to observe precisely how and the extent to which your own applications and workloads actually use your storage.  See “hIOmon Benefits”, “hIOmon Tools Overview”, and the documentation section for more information.

A free demonstration version of the hIOmon WIOP that supports both workstation and server is also available for download.


What's New


The hIOmon "I/O Trender Display" now includes the "Synopsis" display option, which provides a brief, general summary of key performance values along with the associated time context.  See the hIOmon I/O Trender "Synopsis" Display screenshot for an illustration of the Synopsis display.

The new "Synopsis" display option is another unique feature of the hIOmon software that promotes a "top-down" approach to understanding and analyzing storage I/O operation performance based upon empirical metrics that reflect how you actually use your storage devices.
