Primary Server Load balance

I have 5 Primary Zen 11.2.4 servers running on SLES 11 sp3 with around 6000 workstations.
We have have just upgraded from 1 primary server to 5.
We are adding another 6000 workstations to replace some old xp machines.
All primary servers are at central location with workstations at 60 locations with gb connection (school system)
How do i check and ensure load balancing will happen and ensure the load is spread among all primary servers. Looking to add a secondary server at each location.
Thanks

The only way you can do this (without some kind of external load
balancer) is to create your loaction/network environment rules (closest
server rules) with the primaries placed in a group.

Re: Primary Server Load balance

Correct,

Placing Primaries in a Group is the Recommended Method IMHO.
What this will do is cause the order of the servers to be presented to
each device in a random order that updates upon each refresh.

This will result in a virtual even distribution of all of the primaries
among all of the devices.

I would recommend this configuration even above Hardware Solutions such
as an L4. An L4 is great for unintelligent products to balance the
load, but ZCM has so much intelligence, retry, load balancing,
error-handling, etc.. that generally an L4 solution will degrade it.

Now, I know quite a few customers using L4s but IMHO the only reason
they make sense to use with ZCM is because so much money was spent on
them that I.T. needs so make heavy use of them for everything.

Yep, I don't know of any using a Load balancer infront og ZCM - but if
you have a real major setup you could do it.

Ok thanks.
I have created the group and added the primary servers to group. do i need to created the closest server rules or setup locations? Management looking for answers to how this works.
