摘要： A “LUN Table” enables Logical Unit Number (LUN) mapping/masking within an IOV adapter included in a Serial Attached Small Computer System Interface (“SAS” or “Serial Attached SCSI”). A plurality of System Images (“SI”) share block storage through the SAS. The IOV adapter includes one or more Virtual Functions (VF), a Physical Function (PF), and a LUN Table within the PF. The VF allows each SI to communicate I/0 requests with a storage device through the PF. The LUN Table maps the I/0 requests to unique locations within the storage device. Each SI is isolated from all other SIs. Interference between each SI is avoided. A VIOS or a LUN mapping/masking SAN are not required. I/0 latency, processor overhead and storage cost are improved over prior LUN mapping/masking solutions.

摘要： Mechanisms are provided for detecting changes in virtual storage device configurations. The mechanisms detect an event corresponding to a change in configuration of a virtual storage device. The virtual storage device is comprised of a plurality of portions of a plurality of physical storage devices. The mechanisms further, in response to detecting the event, determine if the change in configuration of the virtual storage device results in a change in the types of physical storage devices that are part of the virtual storage device. Moreover, the mechanisms further transmit a notification, in response to a determination that the change in configuration of the virtual storage device results in a change in the types of physical storage devices that are part of the virtual storage device, of the results of the change in configuration of the virtual storage device to one or more registered recipients registered to receive such notifications.

摘要： Automated paging device management is provided for a shared memory partition data processing system. The automated approach includes managing a paging storage pool defined within one or more storage devices for holding logical memory pages external to physical memory managed by a hypervisor of the processing system. The managing includes: responsive to creation of a logical partition within the processing system, automatically defining a logical volume in the paging storage pool for use as a paging device for the new logical partition, the automatically defining occurring absent use of a filesystem, with the resultant paging device being other than a file in a filesystem; and automatically specifying the logical volume as a paging space device for the new logical partition and binding the paging space device to the new logical partition, wherein the logical volume is sized to accommodate a defined maximum memory size of the new logical partition.

摘要： A method for controlling input and output of a virtualized computing platform is disclosed. The method can include creating a device interface definition, assigning an identifier to a paging device and configuring commands useable by a virtual input output server. The commands can be sent to the input output server and can be converted by the input output server into paging device commands. A hypervisor can assist in facilitating the communication configuration. Other embodiments are also disclosed.

摘要： A method, apparatus and computer instructions for storing data relating to the switch in a context switch history containing a number of prior context switches occurring prior to a current context. The storing of data occurs in response to a change in context for a direct memory access resource. Portions of the direct memory access chain of requests are freed using the context switch history to form freed portions, wherein the freed portions are reused for requests.
