COD Boards
A COD board is a system board that has been configured at the factory for COD
capability. COD boards come in the same configurations as standard system boards.
The number of CPUs per COD board depends on the SPARC Enterprise Mx000
server configuration that you purchased.
COD boards are subject to the same limitations for mixed architectures and CPU
speeds as system boards. Likewise, COD board software requirements, such as the
Solaris OS or OpenBoot PROM version, are the same as those of system boards. A
SPARC Enterprise Mx000 server can have any combination of COD and system
boards. It can even be configured entirely with COD boards.
Once a COD board has been licensed, you can configure it into domains in the same
way as a system board. Until it has been licensed, however, you cannot configure it
into a domain.
COD boards are identified by a special field-replaceable unit (FRU) ID and by a
COD label. Except for their FRU ID, label, and COD capability, once COD boards are
licensed, they are handled by the rest of the hardware and software in exactly the
same way as system boards. COD boards fully support dynamic reconfiguration
operations.
You can order COD boards either when you order your server, in which case they
arrive already installed, or as an option. The SPARC Enterprise M4000 and M5000
servers can not add option COD boards after shipment from the factory; COD
capability for these two servers must be ordered with the server.
For more information about COD boards and replacing COD boards (field-
replaceable units, or FRUs) in your server, see the COD User’s Guide and the Service
Manual.
COD License Purchase
The purchase of a COD RTU license 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. For example, if you have a server with two
COD boards with four processors each, but you will only use six of those processors,
all you need is six licenses. Those six licenses can be used by all eight processors, but
only six at a time.
At least 50 license keys can be installed on a SPARC Enterprise Mx000 server. A
COD license has no expiration date.
