Memory usage?

[RichTJ99]

Hi,

I have been playing with freenas & had a quick question about memory (ram) usage. I have installed Virtualbox, Plex, and subsonic. Its only me playing with the box.

I have a few VM's running (win8 (1gb), win 7 (512mb), and another win 7 (1gb). I had all 3 VM's running & sitting idle. I was playing with VNC but really doing nothing at all.

I went to my memory usage and saw the screen shot. I shut down the windows VM's & then you can see the drop. Is that normal to be using all the system memory for 3 vm's?

I have:

Supermicro X10SL7-F-
32GB ram
Xeon 1231v3

Am I reading the memory usage correctly? Was I maxed out & then using nothing?

Is there a command line I can run to check memory usage?

Thanks,
Rich

If by that you mean that the lines seem to all drop to 0 at the end of the graph, that's just a bug in how the graphs display. The graph also isn't quite real time. If you want to see how much memory was freed up, you should wait a bit and check again.

Hat said, FreeNAS is pretty good about using most of the memory it has available most of time. Your ARC will grow and shrink as necessary to use the free RAM,but will also release some when other applications need it.

So if I want to run 5 VM's using 4gb of memory each (20gb used) - how can i tell if that will work or cause problems?
