Hi,

After testing Proxmox very successfully for some services I run for clients, I would like to pursue consolidating a bunch of Linux hardware onto a large server.

Is there a maximum RAM that Proxmox can use? I have a good lead on a decent server with 64GB and another one for not much more that is 96GB. However some docs on OpenVZ indicate a 64GB RAM limitation.

Further, is there any perceived differences, or can someone share there experiences, between the newer AMD Opterons like the 8-core 6148 and the Nehalem 55xx and 56xx CPUs? It appears that the Opterons have much greater memory bandwidth, though I do not know how significant that is.

Most of the VMs are not very CPU intensive, however they will be doing a lot of PHP/Ruby/etc interpreted language running for web servers, so if there are differences I would appreciate hearing about them.
 
Hi,
i don't want to compare the cpu. But i can tell in two or three weeks my experience with proxmox on two nodes with 4*AMD 6136 CPUs and 64GB each (normaly kvm-only). The componets should arive next week (hopefully).
PVE should be able to use much more than 64GB. And if OpenVZ has such an limit, i guess it's for each VM.
