SAS recommends that you deploy SAS Metadata Server on a 64-bit host system. The SAS Metadata Server is multi-threaded and multi-core server hardware (typically quad core or higher is recommended). A dedicated machine for the SAS Metadata Server is recommended to simplify tuning, management, and diagnostics, but is not required. The disk I/O performance of any server-class system should be sufficient. Memory requirements are highly dependent on the product mix and usage, but 8 GB of RAM are sufficient for most large deployments. For many deployments, 4 GB of RAM are sufficient and should be considered a minimum, unless the specific deployment is tested and verified to require less memory.
