When it comes to managing data, the amount of storage required for optimal operations is just one of the aspects to account for. In addition to storage, a skilled SAN admin would also inquire on how fast or slow it is, checks for potential bottlenecks and determines whether it meets your needs.
is a small, but nifty piece of software that enables you to run storage performance tests against files, partitions, physical disks and other options, such as SQL servers. The app comes as a replacement for
, a benchmarking tool that Microsoft has retired.
While it can be argued that the lack of an interface is a setback, you should know that the application is an advanced tool that addresses professionals who commonly manage Storage Area Networks. Consequentially, following a quick setup, you are able to access the app via Command Line.
The idea behind the utility is to help you determine the overall performance of various storage solutions, such as partitions, disks or perform SQL server I/O activity. You should know that the tool allows you to customize the test according to the parameters you are interested in.
Therefore, you can set the CPU affinity, test duration, block size, balance queues, base target offset, sequential access hints and even set up the app to display a progress indicator.
Once the test is completed, the program supplies you with a description of the test where you can preview all the settings you opted for and most importantly, the results of the performance analysis. It is important to note that the utility provides very detailed information about the latency of the storage solution along with IOPs statistics in units of milliseconds if required.
The results are provided in a plain text file that includes data such as the test time, thresh count and the logical processor count. You can also receive a summary of the test in an XML format by inputting a -rxml request.
Even though it could use a feature to help you analyze and interpret the results more efficiently,  Diskspd is a handy tool that can help you perform performance diagnosis for a wide variety of storage solutions.
