[Casper] load balancing servers

[Criss Myers]

HI Dustin 

Why dont you have 1 image that boots PPC and Intel, 10.5 can boot both, 

As far as the netboot servers are concerned, ID numbers above 4096 can
be servered from mulitple servers, doesnt have to be the default image,
as long as the same image is on more than 1 server, the client will only
detect the image once and when it requests it it will get it from the
server that responds first, it should work across subnets as well no
problem.

Hey quick question on that, we have two different netboot images up on
our netboot servers, a 10.4 image that the PPC machines netboot to and a
10.5 that the intels netboot to.   That was the easiest division I could
think of to make sure that all machines netboot w/o and issue as about
half of our PPC machines would not be able to run leopard.  In any case
I’m wondering if load balancing in the manner you were talking about
would still work if I have multiple servers that are all identical with
the ID’s all above 4096 for all netboot images?   Or will it only work
if there is one image?    Also will this work across subnets the same? 
We currently are netbooting across subnets but only to one server.   
Sorry for all the questions and thanks in advance!

Hi, 


  

If you make the netboot id above above 4096 and put the image on both
netboot servers as their default image, then the netboot servers will
auto load balance between the two, the client will pic the quickest
image to boot from.

Anyone done this with casper yet through the JSS?  I want to have
multiple netboot and image servers in one subnet and use mass edit for
the auto run data.  So I have two servers set up, both on the same
subnet but with different IP ranges on different DHCP ranges both behind
NAT routers. 

As far as I can tell, the JSS will point new netbooting clients to the
other server, but how will it know to do so, and at what point does it
start to auto balance?

thanks,
