I've tried to search the internet for a couple of days now trying to figure out how much physical memory I need in my VMware'd server. English is not my primary language and I have some problems understanding all the terms and figures, so I figured I could post a question with my specific config:
1 physical server running VMware vSphere 5.x
2 Viritual servers, server 1 has 4GB RAM and server 2 has 8GB RAM
This means that my guest OS'es has a total of 12GB RAM, and here's my question: How much physical memory should I install in my server? The way I see it there's 3 different options:
1. Install a total of 26GB RAM (((guest os + guest os) x 2) + 2GB extra for the vSphere)
2. Install a total of 14GB RAM (guest os + guest os + 2GB for the vSphere)
3. Install a total of 18GB RAM (biggest guest os x 2 + 2GB extra for the vSphere)
As mentioned I don't get the official VMware documentation, sorry for this. Hope you can give me a clear answer to my specific setup.
