I have a HP ML380gen8 with 1 Xeon processor E5-2620 (6core) and 12 Gb RAM. There is a raid5 config with 4 disks (300Gb sas).

On this machines run VMware ESXi5 with a datastore of 838 Gb.

My question:

i want to install 2 virtual machines on the ESX.

1.  SBS2011 (10 concurrent users, mainly office apps are being used (word/excel docs)
2. Win2008R2 RDP server (2 concurrent users)

What is the best config for both machines. In ESX i can set the "number of virtual sockes" and
"cores per socket". For the best performance. How many do i have to assign?

How many ram i have to assign to the machines?
Are there any other things i need to configure?

thx!

As a base I normally start with 2 CPU, 2 cores and 4GB of memory. I then leave it for a couple days and monitor the performance, if you look under the virtual machines tab you get a quick overview of what the CPU and memory are doing. I also speak to the users and see what the feel is like. If the VM needs more resources I up it, and repeat. Works well for me.

Is it possible to change the amount of cpu and cores a few times after shutdown the machine?

But 4GB is much to less for a SBS2011 with Exchange in it, isnt it?

CPU must be changed with the machine powered off. You can assign additional memory without shutting down. For the SBS server start at 8GB or 10GB and work from there.

Start with One vcpu, RAM depends on the requirements.

In such a server perhaps you can try with 8 GB for the SBS and 4 GB for the RDP server (Terminal server?)

Try not to over allocate which is a common mistake.

Start out small and grow

SBS2012 - 2 CPU sockets 16GB RAM

Terminal Serverv2 CPU sockets 8GB

Your host is really low on RAM put in at least 32GB

Is it 128 GB? That seems more in line with a gen 8 server.

Also install on a SD card or USB flash drive. Rather than on the SAS disks.
