  • Page 12: Cod Boards

    High-end servers support any combination of COD boards and system boards. For Sun SPARC Enterprise M4000/M5000 (midrange) servers, COD boards can be ordered only at original purchase. Midrange systems can be configured with COD boards or system boards, but not both.

  • Page 13: Cod License Purchase

    COD License Purchase The purchase of a COD RTU license from the Sun License Center entitles you to receive a license key, which enables the appropriate number of COD processors. A license key can grant access to multiple RTUs. A COD license is assigned to a specific server, one license per processor (CPU). All the licenses assigned to a server are handled as a floating pool of licenses for all the COD processors installed on that server.

  • Page 14: License Allocation

    License Allocation The software allocates COD licenses automatically on a first-come, first-served basis. However, you can reserve licenses if you want to make sure a specific number of COD licenses are allocated to a particular domain. Licenses are allocated to COD resources either when a domain with a COD board is powered on or when a new COD board is installed and powered on.
