How to check VPLEX's cache capacity

Hi everyone!

I am doing some tests and at the end I will have to write a serious report. That is why I want to note down all the important data. I am trying ot figure it out how can I check the cache of my VPLEX. Is there any command on the CLI that I can execute or is the cache a standard value for all the VPLEX? My VPLEX has 1 engine, i.e. two directors.

Thanks
