I am trying to build a cluster of HP DL380 servers, and I am having a lot of trouble getting them to do what I want. I have tried Windows Server 2003 and 2008, and am now exploring the possibility of a Linux solution and was hoping somebody could point me in the right direction.
I am trying to make 1 powerful system that will let me throw a large amount of services on it. I manage a network of 1000+ computers, and will need things like DNS, DHCP, Mail Serving, and Web Serving. I am currently doing these tasks on individual servers, but am trying to achieve better redundancy and better utilization of my available power.
I have looked at Linux clustering but it seems to be similar to Windows clustering, where you are still only running 1 service on 1 machine. When that 1 fails, then another takes over. But I want to run all services on all machines all at once. If my utilization get to high, then I want to be able to just buy more servers and add them in.
If people could pass on their wisdom in this matter, I would greatly appreciate it. I have a basic knowledge of Linux, but am no expert. Thanks for any help anyone can provide...

I think the best way to do what you are trying to do would be to have 1 server to run ha lvs as a load balancer and then 2 high power servers as your cluster servers, you could if you wish have a secondary load balancer to make things more redundant.
This works well and I have it running in large scale on a global client. They are running DL380's for the servers.
I should also mention that I have a HP MSA500 capable of connecting 4 nodes, to use as a shared storage.
Thanks kentyler for your response, I have taken a look at the Load Balancing solution. But I was leaning away from that, as it needs to have 1 or 2 servers sitting basically unused running the cluster. I was hoping to be able to run all my servers at 100% utilization if need be...
