The CZ (Collaboration Zone) contains most of the Open Computing Facility (OCF) computing platforms and will continue to serve the majority of LLNL OCF users. The RZ (Restricted Zone) contains a number of smaller systems serving a subset of the LC user community. The shared Infrastructure Zone (IZ) contains resources shared by both the CZ and RZ and include the Lustre file systems and OCF storage. The combination of these three "zones" is referred to as "The Enclave."
