摘要:
Disclosed is a computer implemented method, computer program product, and apparatus to establish at least one paging partition in a data processing system. The virtualization control point (VCP) reserves up to the subset of physical memory for use in the shared memory pool. The VCP configures at least one logical partition as a shared memory partition. The VCP assigns a paging partition to the shared memory pool. The VCP determines whether a user requests a redundant assignment of the paging partition to the shared memory pool. The VCP assigns a redundant paging partition to the shared memory pool, responsive to a determination that the user requests a redundant assignment. The VCP assigns a paging device to the shared memory pool. The hypervisor may transmit at least one paging request to a virtual asynchronous services interface configured to support a paging device stream.
摘要:
Hardware transmit and/or receive queues in a self-virtualizing IO resource are virtualized to effectively abstract away resource-specific details for the self-virtualizing IO resource. By doing so, a logical partition may be permitted to configure and access a desired number of virtual transmit and/or receive queues, and have an adjunct partition that interfaces the logical partition with the self-virtualizing IO resource handle the appropriate mappings between the hardware and virtual queues.
摘要:
Error handling is simplified for a self-virtualizing IO resource that utilizes a physical function adjunct partition for a physical function in the self-virtualizing IO resource to coordinate error recovery for the self-virtualizing IO resource, by restarting each virtual function adjunct partition associated with that physical function to avoid the need to coordinate error recovery within the logical partitions to which such virtual function adjunct partitions are assigned.

摘要:
A vendor independent partition interface between a logical partition and an adjunct partition associated with a self-virtualizing IO resource is used to effectively abstract away vender-specific interface details for the self-virtualizing IO resource. By doing so, vender-specific implementation details may be isolated from the operating systems resident in logical partitions, thus requiring only changes in vendor specific firmware in order to support new or revised self-virtualizing IO resources.

Systems and methods to forward data frames are described. A particular method may include generating a plurality of management frames at a controlling bridge. The management frames may include routing information. The plurality of management frames may be communicated to a plurality of bridge elements coupled to a plurality of server computers. The plurality of bridge elements are each configured to selectively forward a plurality of data frames according to the routing information.

Systems and methods to forward data frames are described. A particular method may include associating a fiber channel forwarder with a bridge element. The fiber channel forwarder may be one of a plurality of fiber channel forwarders coupled to the bridge element. A data frame received at the bridge element may be forwarded to the fiber channel forwarder.

Systems and methods to multicast data frames are provided. A particular apparatus includes a plurality of computing nodes and a distributed virtual bridge. The distributed virtual bridge includes a plurality of bridge elements coupled to the plurality of computing nodes. The plurality of bridge elements are configured to forward a copy of a multicast data frame to the plurality of computing nodes using group member information associated with addresses of the plurality of server computers. A controlling bridge coupled to the plurality of bridge elements is configured to communicate the group member information to the plurality of bridge elements.
摘要:
The present invention relates to a method for the safe shut down of an operating system. The invention utilizes a shutdown-monitoring program that is running in an initiator operating system to periodically transmit and pass-through SCSI command to a SCSI target to determine if a shutdown operations is to be performed upon the operating system. In response to the SCSI command the SCSI target returns data back to the initiator operating system, wherein the shutdown-monitoring program analyzes the data. In the event that the shutdown-monitoring program determines that the operating system is to be shut down, then an operating system shutdown is initiated using at least one appropriate API that is provided by the operating system.
