I/O management's analytical tools

Within I/O management, there are several analytical tools a data center manager can use. For example, I/O management can quickly identify if performance issues originated in the storage network or if they originated within the application server. This allows I/O management systems to identify potential issues before they happen. There are several other pieces of information that I/O management adds to the toolbox.

Using historical performance information, I/O performance trending can benefit the IT administrator during proactive and reactive analyses of performance. Unlike other tools which cannot supply historical performance information, I/O management can consolidate, trend and track the information to create performance charts that the IT administrator can use to pinpoint the problem immediately. Some of the problems I/O performance trending can identify are I/O latency issues and operating system command queues-both of which can affect the speed and consistency of I/O, which can then affect overall application performance.
