Hardware and database software requirements are driven by the number of client computers being updated in your organization. The following tables offer guidelines for server hardware and database software, based on the number of client computers being serviced. A WSUS server using the recommended hardware can support a maximum number of 60,000 clients. Both the system partition and the partition on which you install WSUS must be formatted with the NTFS file system.

WSUS 3.0 cannot be installed on a compressed drive. Please check that the drive you choose is not compressed. |

These guidelines assume that WSUS clients are synchronizing with the server every eight hours (for the high-end configuration) or every two hours (for the super high-end configuration). If they synchronize more often, there will be a corresponding increment in the server load. For example, if clients synchronize twice a day, the load will be twice as much as if they synchronize once a day. |

Increasing the number of languages will also increase the load. Supporting five languages rather than one language will approximately double the size of the content directory. |
