![]() The bad news is that IOAT doesn't provide any specific guidance for improving storage subsystem speed. The good news here is that the IOAT confirmed with quantitative data what I suspected qualitatively. Overall, IOAT told me I had high potential for I/O optimization, and it detected moderate I/O performance issues. My laptop's hard disk drive thrashes almost all the time. Ouch! My values here were consistently far above normal. Admittedly, the system was pretty quiet during a good portion of that day. I performed a 24-hour analysis on my Lenovo laptop running Windows 10. Actually, let's look at a couple of my results charts to see if any useful information jumps out. I don't know about you, but I'm able to interpret I/O performance results only to a certain point. The ability to submit your results to Condusiv is actually a really nice service. Condusiv does not charge for this service, but if you are experiencing I/O inefficiencies, you might want to discuss evaluating their I/O reduction software as it could be more cost-effective than purchasing hardware upgrades. The tool offers the option to submit your results to Condusiv and an engineer can step through the results with you. D: Submit Results: Optionally, you can transfer your report data to Condusiv to get the opinion of their support engineers.C: Conclusion: This graph tells you the I/O issues that deviate beyond the median range and your potential for performance optimization.B: I/O Assessment Metrics: Expand this section to see sub-reports that show an hour-by-hour topology for each key metric.A: Systems Included in Report: This summary shows the overall storage system state at a glance.Here's a screenshot showing IOAT in active evaluation mode. Closing it will automatically cancel the data capture. You'll need to keep the application running over the duration of the testing period. When you're ready, click Start Data Collection and minimize the application. You may have noticed in the IOAT application fine print that Condusiv gives you a six-month license. Credentials: You should specify a member of the Domain Admins global group to ensure WMI can capture disk I/O activity on all monitored hosts.Condusiv recommends collecting data for five consecutive production days. The idea here is you want to capture all the peaks and valleys of your systems' ordinary usage patterns. Test duration: You can test between one and seven days, starting now or at 12:01 a.m.Note that you do not have to install IOAT on every monitored system. As you might expect, the remote data collection takes place via Windows Management Instrumentation (WMI). Target systems: Specify a comma-separated list of DNS names and/or IPv4 addresses on all systems you want to evaluate.Go ahead and download the software sooner rather than later! To get us there, Condusiv makes an I/O Assessment Tool, which is currently free for use. You are much more likely to have your purchase request for a new hard drive approved if you can use hard data and graphs to demonstrate to your boss how and why a system performs slowly and how it can benefit from a new, faster storage system, or other performance enhancing solutions like I/O reduction software. What isn't obvious is how to generate meaningful, quantitative statistics to back up your hunch that your server's storage subsystem feels slow. This benefit speeds up your system-all of these are obvious, elementary points. The higher the IOPS value, the more data the disk can read or write. The key performance metric for traditional hard disk drive (HDD) and newer solid-state drive (SSD) storage is the input/output (I/O) operations per second, also called IOPS.
