|Storage technology is complicated, but the evaluation of your storage I/O performance need not be.|
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 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
Are easy to understand and use
Reflect how you actually use your storage
|An Automotive Approach|
Automobiles are complex in design and construction. As a result, there are a number of factors that can impact performance such as: engine type and configuration, transmission, tires, and aerodynamics. Traffic and weather conditions along with terrain can also influence performance.
Nevertheless, there are several key metrics that you typically use when evaluating the performance of your automobile. Fuel economy (miles-per-gallon) is a common, prominent one.
Similarly, you consider how you actually use your automobile. Do you usually do a lot of stop-and-go city driving? And how about fast and lengthy highway/expressway driving?
Of course, another consideration is the typical and maximum number of passengers.
Basically, what are the particular profiles that reflect how and where you in fact use your automobile and its performance?
|The hyperI/O Approach to Storage I/O Performance Analysis|
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).
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.
