Well, let me explain a little more. I actually have two Server 2012 boxes running with 640MB of static RAM, on Hyper-V on server 2012 R2. (I thought it was 512MB)
One of the boxes is my FTP box, which I run the IIS role to configure FTPS (FTP over SSL), and is also my DFS server (about 12 shares for 6 servers, approximately). Running a PoSH command:
(Get-Counter -Counter "\Memory\Available MBytes" -ComputerName FTP01).CounterSamples.CookedValue
I currently have 96MB of RAM free on that VM. When I log in via console to this VM, all I get is a PowerShell command prompt but it's snappy. No cursor lag, and the login is quick.
My other 2012 VM with 640MB of RAM is my RDS box (Remote Desktop Services). All I have configured on here is the RDS role, and the RD Gateway Role Feature (this box allows me to RDP into any of my servers over WAN, without having to configure and forward a port for each server -- makes things simplistic when I use Devolutions Remote Desktop Manager so I can get to all my servers from work, or wherever I am). It's also configure with a core install, and that same PoSH command returns 184-212MB RAM free (if I run it over and over). Meaning it's running on as low as 428MB of RAM, with 4 managed connections on that RDS role.
I'm honestly surprised that I was able to get these working like this, but it does. The only thing I hate is that these boxes have a 30GB VHDx. If CentOS could host RDS and DFS for me, I would get rid of these VMs just so I could free up 20-25GB of storage space.
On a similar note (similar to my RDS box), I have a CentOS 6.4 x64 box setup with 2 vCPU and 512MB RAM (running on Hyper-V 2012 R2) that is my RDGATEWAY server. Very similar to RDS, but it runs an application called Guacamole which gives me RDP/SSH/VNC capabilities from any HTML5 enabled browser (i.e., so I can RDP to all my servers over LAN or WAN, from my Chromebook). It's only using 220MB of the 512MB of RAM available. That's when brokering 3 active connections as well. I wrote a blog about Guacamole a few months back, if you're interested in reading (I don't write many blogs -- just when I feel like it):
Looks like I have a third Server 2012 VM with low RAM, but it is running with 512MB static. All it does is host my UniFi AP Controller software. It has 71MB of RAM free, currently, and is using a 25GB VHDx. That software is only supported on Mac and Windows, but not Linux (so strange). However, it's a java app so I'm sure I could pull out the .jar and get it to work, just haven't had the time to try.Edited by tycoonbob - 10/2/13 at 7:02am
