VMware Labs also breaks down a list of Top Flings, sorted for your convenience into either the latest or the most popular. Currently the site offers a total of 19 interesting and useful flings.
This week the VMware Labs site quietly launched the first fling of 2011, called IOBlazer. It's described as a multiplatform storage stack micro-benchmark tool. The software is released under the MIT License, and it comes from Davide Bergamasco, who works in the VMware performance group.
VMware Labs describes the new fling:
IOBlazer runs on Linux, Windows and OSX and it is capable of generating a highly customizable workload. Parameters like IO size and pattern, burstiness (number of outstanding IOs), burst interarrival time, read vs. write mix, buffered vs. direct IO, etc., can be configured independently.
IOBlazer is said to have evolved from a minimalist Microsoft SQL Server emulator, which focused solely on the I/O component of the workload. The original tool had limited capabilities and generated a very specific workload based on the SQL Server I/O model. But IOBlazer has been created with a far more generic I/O model in mind, and comes with a very useful new feature -- the capability to play back VSCSI traces captured on VMware ESX through the vscsiStats utility. This allows IOBlazer to generate a synthetic workload that is absolutely identical to the disk activity of a virtual machine, which ensures 100 percent experiment repeatability.
If you want to get your hands on this latest fling or any of the other 18 experimental flings that are "meant to be played with and explored," check out the VMware Labs website and start downloading them now.
