I am setting up large GPFS cluster where there will be total of 24 CES Nodes (12 in each data center). I am planning to use all 24 CES for NFS services and 16 for SMB services because 16 is the maximum number of node alllowed to run SMB services. If anyone have done this kind of setup I would like to know how you achieved it or any idea on how to achieve this ? Thank you for your help

Please setup some time to discuss with myself and @Madhav. These large setups can be be smooth if we are careful in planning. At the moment we seem to need more details.
