20080301692 | FACILITATING ACCESS TO INPUT/OUTPUT RESOURCES VIA AN I/O PARTITION SHARED BY MULTIPLE CONSUMER PARTITIONS - At least one input/output (I/O) firmware partition is provided in a partitioned environment to facilitate access to I/O resources owned by the at least one I/O firmware partition. The I/O resources of an I/O firmware partition are shared by one or more other partitions of the environment, referred to as consumer partitions. The consumer partitions use the I/O firmware partition to access the I/O resources. Since the I/O firmware partitions are responsible for providing access to the I/O resources owned by those partitions, the consumer partitions are relieved of this task, reducing complexity and costs in the consumer partitions. | 12-04-2008 |

20090150504 | AUTO-CONFIGURATION OF AN INTERNAL VLAN NETWORK INTERFACE - Apparatus and storage media for auto-configuration of an internal network interface are disclosed. Embodiments may install an internal VLAN manager in a logically partitioned computer system along with network agents in each of the partitions in the logically partitioned system to facilitate configuring an internal communications network and the corresponding internal network interfaces in each participating partition. In particular, an administrator accesses internal VLAN manager, selects an internal VLAN ID, selects each of the participating partitions, and configures the communications network with global parameters and ranges. The internal VLAN manager then generates partition parameters and incorporates them into messages for each of the partitions selected to participate in the internal network. Each of the participating partitions receives one of the messages and, in response, invokes the corresponding network agent that extracts partition parameters from the message and creates or re-configures an internal network interface based upon the parameters. | 06-11-2009 |
