Just a few thoughts:
  • Don't overlook Lustre, the high bandwidth distributed NFS.
  • VM is a run in the opposite direction, but for some things it can be appropriate. Watch your reliability aand administrative models, as more VMs is just that much more load on them.
  • Clusters are usually homogenous. There are other tactics for distrbuted processing that are more heterogenous-friendly.
  • A remote X like vnc often has much higher performance, due to low Xserver latency.

CCS_CONFIG_VALIDATE(8)					      System Manager's Manual					    CCS_CONFIG_VALIDATE(8)

NAME
ccs_config_validate DESCRIPTION
Usage: ccs_config_validate [options] OPTIONS
-h Print this help, then exit -V Print program version information, then exit -v Produce verbose output Validating XML configuraton files: -f configfile Validate an alternate config file without preloading it with default values. -l configfile Validate an alternate config file with preloading of default values (recommended option). Advanced options: -r Force validation of runtime config -C config_loader Override config plugin loader -t tempfile Force temporay file to tempfile -n Do not remove temporary file -o Overwrite temporary file (dangerous) DEFAULT
Default operation for ccs_config_validate is to load the currently configured environment and verify the outcoming configuration. Example 1: current environment uses a configuration file (/etc/cluster/cluster.conf). The user modifies cluser.conf and executes ccs_config_validate without options. The tool will validate the modified cluster.conf after including default values. Example 2: current environment is set to load the configuration from LDAP. Users modifies LDAP databse and before pushing the change to the nodes, she/he can issue ccs_config_validate to verify the contents o the LDAP database automatically (as long as the correct LDAP environment is set in the cman/cluster sysconfig/defaults files).
