Subsystem testing
Along with generic system testing, you can examine specific subsystems. This may be more useful in situations in which you suspect an issue, rather than for general knowledge or trend analysis. It's also useful if you just want to know the capabilities of your systems, since the tools you'll be shown focus more on what the system can do than on how it has been performing. The biggest barrier to testing subsystems is that many of the tools won't work from the hypervisor level. The subsystems we'll examine are disk, memory, and network.
Disk I/O testing
A tool commonly used for examining disk performance is IOMeter, which was created by Intel and is now an open source project. The official site and download are accessible at http://www.iometer.org. More recent but somewhat less stable versions are available at http://sourceforge.net/projects/iometer/. It runs on all current Windows operating systems including Hyper-V Server, and all non-Windows operating systems that can run...
