Ask about rhel cluster with many cores.

Hi everyone!
I plan to build a cluster. Anyone help me some problem:
1. How many node can rhel support in a cluster system?
2. How many processor or core can rhel support in single node?
3. How many processor or core in a node and system give the maximum benefit.
Sorry if my question is silly.
Thank in advance

CRM_UUID(8)							  [FIXME: manual]						       CRM_UUID(8)

NAME
crm_uuid - get a node's UUID SYNOPSIS
crm_uuid [-w|-r] DESCRIPTION
UUIDs are used to identify cluster nodes to ensure that they can always be uniquely identified. The crm_uuid command displays and modifies the UUID of the node on which it is run. When Heartbeat is first started on a node, it creates a UUID (in binary form) in /var/lib/heartbeat/hb_uuid. This file can be read and written by means of crm_uuid. Note There are very rare circumstances when crm_uuid should be used to modify the UUID file. The most common is when it is necessary to set a node's UUID to a known value when creating a new cluster. OPTIONS
--write, -w Write a UUID value to the /var/lib/heartbeat/hb_uuid file. Warning Use the -w option with care, because it creates a new UUID value for the node on which it is run. Various scripts across the cluster might still use the old value, causing the cluster to fail because the node is no longer associated with the old UUID value. Do not change the UUID unless you changed all references to it as well. --read, -r Read the UUID value and print it to stdout. SEE ALSO
