[cod] Mmmm... cores

[Rick Payton]

It was one VM hosting all the game servers, with about 9 other VM's hosting various websites and applications. Never occurred to me to run multiple VM's for multiple game servers. OOhhhhhh gotta test that setup :P

Interesting. How many VEs did the ESX host run? If it only ran one, then
it sounds quite okay, but if it ran one for each server, then I am very 
impressed! Not only does the host have to task-switch between each server 
in the VEs, it also has to switch between each VE.

When it comes to L4D, it runs at a pretty low server-FPS of ~30, and it
is generally not a game where accuracy at high speeds is important. So L4D
doesn't require the same real-time performance as e.g CSS. COD4 I don't 
know and currently can't check the tick-rate of, but I imagine it is 
significantly lower than 100, making it also less dependent on RT-performance. 
Wonder how 100 tick (by config) CSS servers would fare on a host with 8 
cores and 8 VEs...

Cheers,
Einar

	Do virtual servers actually work well with game-servers? We use virtual servers for
	a lot of things, but for our game servers we use only pure physical hosts. I would
	think that real-time properties, which are quite important for game-servers as
	opposed to webservers, sql-servers and mailservers, would be quite poor for 
	virtualised servers.
	
	Which virtualisation solutions have proven to work for past-paced games? And is
	there a certain trick to setting them up, such as binding a virtual server to a single
	core?

		Each game server, as far as I know will only use a single core so virtual is what this bad boy was made for.  :-) This machine in our environment running Linux game servers, we would be able to run 40-50 game servers on this single box! Currently we run 6-10 windows servers on a single dual core xeon w/8gigs of ram. Remember Vmware allows over commitment of memory!!! Most others do not.
