VMware Virtual Machine Provisioning disk I/O test analysis

In the implementation of individual projects, often have colleagues or customers ask "VMware virtual machines have three provisioning, thick provisioning delay to 0, thick provisioning format, which is good for thin provisioning", depending on the specific circumstances, from different points of view, the answer is to choose the most appropriate, not the best.

A while ago, I studied Wang Chunhai's blog, "Virtual Disk performance test", Mr. Wang tested the different storage, the different virtual machine format disk performance, the individual benefited a lot, this blog will expand the teacher Wang's test, testing the thick provisioning format and the thin provisioning format in the transmission of different pieces of the IOPS.

Test design: In a Windows 2008 Datacenter System virtual machine, add new disk E disk to thick provisioning format, add new disk F disk for streamlined provisioning format, use the Iometer tool for different blocks, different reading and writing ratios of tests.

Test steps:

1. Build a thin provisioning disk of 5GB size and 5GB size respectively

2. Enter the Windows 2008 system to initialize the disk, select GPT disk partition format
