Is there any way to create a VMvmare server cluster?

Hi,

I have two machines which don't support install ESXi, these machines are running centos 5 with no X and I installed vmware server 2.0.

My question is, is there any way to create a vmware server cluster like is possible create in ESX?

I know in ESX once you create a cluster, the resources are increased since resources are added. Is there any way to do same thing with vmware server 2.0?

Also is there any other option for my machines, I don't want to install X since the machines don't have much resource.

Thanks in advance.
