The present invention is a window picture system that includes a retractable window shade pulled down from a top portion of a window, one or more images that include a selected one of one or more pictures, one or more photographs and one or more drawings, a window frame with a bottom and a window sill with a top surfacing. The system also includes a three dimensional projector that displays a selected one of the one or more images and one or more slide shows onto the window, an image change button disposed on the top surfacing of the window sill, a camera SD card inserted into the three dimension projector, a battery and a scanner utilized to scan the selected one of the one or more images and one or more slide shows.

Window picture system

Apparatus and program product for assigning or confirming multiple address identifications to a single channel adapter. A server contains multiple partitions connected to a single channel adapter which is used to send data and commands to a fabric. A request is sent to the fabric on behalf of each of the partitions, and the fabric assigns or confirms and returns to the adapter, an address identification associated to each partition on whose behalf the request was sent. The assigned or confirmed address is used to communicate between controllers connected to the fabric and the associated partition through the same channel adapter.

Obtaining multiple port addresses by a fibre channel from a network fabric

An apparatus and computer program are disclosed for collecting data about the transmission of network packets that are associated with specified applications. The packets are transmitted through a communications network fabric that is used to couple data processing systems together. A particular existing single bit in a frame header definition is selected. The bit is defined as part of the standard frame header by a communication protocol as an available bit in the frame header. The standard protocol is unchanged by the selection of this bit. An application is specified to be monitored. The selected bit is then set in each network packet that is generated by the specified application. The fabric collects performance data for each packet that has the bit set. Thus, the fabric collects performance data about a transmission of each packet that is generated by the application when that application is setting the bit.

Apparatus and computer program for identifying selected applications utilizing a single existing available bit in frame headers

An exemplary embodiment of the invention relates to a method, system, and storage medium for resolving contention issues by a channel in a fibre optic switch environment that occur during channel program execution. The method comprises a channel receiving a status packet indicating a device is no longer busy. The method also includes specifying whether the channel intends to re-initiate a channel program that previously resulted in the device busy status. If the channel does not intend to re-initiate the channel program, a first combination of bits in a re-initiate field of a status-acceptance packet are set which indicate that the channel will take no further action. If the channel intends to re-initiate the channel program, a second combination of bits in the re-initiate field of the status-acceptance packet are set, indicating that the channel will re-initiate the channel program. The method further includes transmitting the status-acceptance packet to a control unit. The invention also includes a system and a storage medium.

Method, system, and storage medium for resolving contention issues during channel program execution

A non-disruptive unassignment of an address from a fabric responsive to a request from a channel adapter. A logout command requests the fabric to unassign an address. The status of the address is thereby changed from active to unassigned and an acknowledgment sent back to the channel adapter.

Method and apparatus for non-disruptively unassigning an active address in a fabric

A computer Input/Output system having a fabric, a control unit (CU) and a host computer including a channel, the channel having a channel port connected by a first link to a channel neighbor port of the fabric, and the control unit having a CU port connected by a second link to a CU neighbor port on the fabric. Then an error is detected in the link or protocol between the channel and the control unit, error data are reported to the channel by the channel, the channel port, the channel neighbor port, the control unit, the CU port and the CU neighbor port and sent to the channel. The error data are provided to the host computer for analysis.

Transfer of error-analysis and statistical data in a fibre channel input/output system

Communication between components having differing protocols is facilitated by a protocol converter coupled between the components that converts communications of one protocol into communications of another protocol. This conversion is performed without requiring code modification to either of the components. The conversion includes translating identifiers of one protocol to identifiers of another protocol.

Communicating between communications components having differing protocols absent component modifications

A computer Input/Output system having a fabric, a control unit (CU) and a host computes including a channel, the channel having a channel port connected by a first link to a channel neighbor port of the fabric, and the control unit having a CU port connected by a second link to a CU neighbor port on the fabric. When an error is detected in the link or protocol between the channel and the control unit, after a retry of the failing operation is performed, error data are reported to the channel by the channel, the channel port, the channel neighbor port, the control unit, the CU port and the CU neighbor port and sent to the channel. The error data are provided to the host computer for analysis.

Transfer of error-analysis and statistical data after retry in a fibre channel input/output system

A computer implemented method, data processing system, and computer usable program code are provided for using identifier virtualization to extend the virtualization capabilities of protocols. A determination is made as to whether a logical entity requires a unique identifier in order to extend a virtualization capability of a protocol. A unique name is assigned that is associated with the logical entity. The unique identifier is requested from a fabric using the unique name. The logical entity is notified that the unique identifier has been established for the logical entity in response to receiving the unique identifier from the fabric. The unique identifier identifies the logical entity within or attached to the fabric.

Method for non-disruptively unassigning an active address in a fabric

A channel adapter non-disruptively removing an address assigned thereto. A logout command is sent from the channel adapter to a fabric requesting the fabric to unassign a given address. The channel adapter is capable of detecting an error if the fabric response does not indicate the requested address was successfully removed.
