Virtual Flash Resource in Virtual Machine

VMware has already given some explanation for vFRC:-


  1.  VMware vSphere® Flash Read Cache® 1.0
  2. Performance of vSphere Flash Read Cache in VMware vSphere 5.5

Here I will show how you can configure:


  1. Add a Flash/SSD Resource on your ESXi host which should not be claimed or used for any other purpose.




  2. Once added you have to share this resource with individual virtual machine disk or whichever is I/O intensive.



  3. The amount of vFRC reservation you want to have along with the desired block size.
