Abstract: Apparatuses, methods, program products, and systems are presented for interrupt migration in connection with migration of a logical partition.

Abstract: A system and method dynamically assign interrupts to a virtual machine from an input/output (I/O) adapter based on I/O metrics of the I/O adapter. An interrupt manager monitors I/O adapter traffic flow metrics such as latency of data transfers, usage levels, and transfers per unit of time. The interrupt manager determines when a traffic flow metric for a virtual machine meets a predetermined performance threshold and updates virtual interrupt assignments in a logical interrupt table to improve performance of the system.

Abstract: Apparatuses, methods, program products, and systems are presented for interrupt virtualization. An apparatus includes an adapter module that detects a switch from a first physical input/output (“I/O”) adapter associated with a logical partition to a second physical I/O adapter associated with the logical partition. The apparatus includes an interrupt module that updates one or more I/O interrupt management structures for the logical partition so that the logical partition receives I/O interrupt information from the second physical I/O adapter and not the first physical I/O adapter without the logical partition being aware of the switch to the second I/O adapter. The apparatus includes an abstraction module that updates physical device information at a hypervisor for the logical partition to reflect the switch to the second physical I/O device.

Abstract: An apparatus, system, and method are disclosed for deploying sensitive communication parameters to a diskless computing device. A parameter structure module is included to store one or more Internet Small Computer System Interface (“iSCSI”) communication parameters in an extendable data structure configured to store a set of basic parameter settings and a set of extended parameter settings. A link module is included to establish a secure link to a diskless computing device over a physically secure connection. A deployment module is included to deploy the extendable data structure over the secure connection to a non-volatile memory in the diskless computing device. The non-volatile memory is configured to provide sensitive iSCSI communication parameters provided by the extendable data structure to a CPU of the diskless computing device during a boot sequence.

Abstract: An apparatus, system, and method are disclosed for distributing configuration parameters. The present invention includes one or more storage devices configured to store data, a first DHCP server configured to process DHCP messages and redirect communications regarding configuration parameters for the storage devices to a second DHCP server, and a configuration datastore configured to store configuration parameters for the storage devices. The second DHCP server may be configured to process DHCP messages and retrieve configuration parameters for the storage devices from the configuration datastore. In certain embodiments, each storage initiator communicates with the DHCP servers, receives the configuration parameters such as iSCSI parameters, and provides the configuration parameters to one or more storage devices.
