[cod] Mmmm... cores

Fri Jan 16 01:24:13 EST 2009

I personally have a windows 08 server VM that can run a 32 man UO server, 32
man COD2 & a 32 man COD5 server at the same time. The most people we know
that have been on it is 35 and it ran fine, the real issue is bandwidth. You
have to have plenty of it.

We are using Virtual Iron on one stack of servers and it will move heavily
loaded VM's to less loaded boxes without reboot them. Simular to Vmotion
from Vmware, just cheaper! :-)

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

I run my game servers in both a VMware ESX and ESXi environment. the ESXi
setup is only pushing a single 14 player game server, but I used the ESX
host to push 8 Left 4 Dead servers, as well as the COD4 and about 5 other
steam based servers, with nary an issue.

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?

Cheers,
Einar

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.
