Abstract: A mechanism uses in-situ bidirectional cable wrapping for determining different cable lengths. A calibration mechanism calibrates the high speed transmitter/receiver pair characteristics, and, thus, optimizes the transmission performance between subsystems. The calibration mechanism mitigates the need for frequent error correction and does not incur the performance degradation associated with error correction techniques.

Abstract: A method and system for enabling dynamic matching of storage utilization characteristics of a host system application with the characteristics of the available storage pools of an attached distributed storage system, in order to provide an optimal match between the application and selected storage pool. An abstraction manager is provided, enhanced with a storage device configuration utility/module, which performs a series of tasks to (1) obtain/collect the correct configuration information from each connected storage device or storage pools and/or (2) calculate the configuration information when the information is not readily available. The storage device configuration module then normalizes, collates and matches the configuration information to the various applications running on the host system and/or outputs the information to a user/administrator of the host system via a software interface.

Abstract: A method, system and computer program product are provided for representing resource sets in a variable format. Variable resource sets are represented in two parts: a system topology domain and a system detail level. Logical entities are allowed to consume variable resource sets to specify the domain and level required in the attachment. Thus, the resource set attachment is made using a domain system detail level, but the actual resources represented are derived dynamically. That is, the elements that were once statically represented by bits in the resource set are now derived dynamically to reflect the system state at the time they are being used.

The control message is sent to a receiver data processing system, wherein the receiver data processing system modifies the data flow to the data processing system using the control message.

Abstract: A computer implemented method, apparatus, and computer program product for dynamically loading a module into an application address space. In response to receiving a checkpoint signal by a plurality of threads associated with an application running in a software partition, the plurality of threads rendezvous to a point outside an application text associated with the application. Rendezvousing the plurality of threads suspends execution of application text by the plurality of threads. The application text is moved out of an application address space for the application to form an available application address space. The available application address space is an address space that was occupied by the application text. A software module is moved into the available application address space.

Abstract: A method for improving the reliability of host data stored on Fibre Channel attached storage subsystems by performing end-to-end data integrity checks. When a read or write operation is initiated, an initial checksum for data in the read/write operation is generated and associated with the data, wherein the association exists through a plurality of layers of software and attached storage subsystems. The initial checksum is passed with the data in the read/write path. When a layer of software in the read/write path receives the initial checksum and data, the layer performs an integrity check of the data, which includes generating another checksum and comparing it to the initial checksum. If the checksums do not match, the read/write operation fails and the error is logged. If the checksums match, the integrity check is repeated through each layer in the read/write path to enable detecting data corruption at the point of source.

Abstract: A process for preparing and storing moist glass-making batch is disclosed, comprising incorporating a surfactant in moist batch so that when the batch is either: a) stored at a temperature below 35° C., it remains free flowing without setting, or b) pre-heated at, or above, 100° C. before supply to a glass melting furnace, it remains free flowing without setting. The moist batch includes from 2% to 10% by weight free water and from 0.0001% to 5% by weight surfactant, which is preferably a soluble soap (for example a carboxylate having from 4 to 22 carbon atoms in its chain) that is incorporated into the batch as it is mixed. The moist batch can be stored for at least 24 hours, and it can be pre-heated to at least 150° C., and remain free flowing without setting.

Abstract: In a data processing system utilizing multiple page sizes for virtual memory paging, a system, method, and article of manufacture for managing page replacement.

Abstract: A mechanism detects cable length in a storage subsystem with wide ports. The mechanism uses in-situ bidirectional cable wrapping for determining different cable lengths. The mechanism under-margins transmitter output to failure for each external port and even for each PHY within a wide port. Based on the transition point from “good” wrap to “bad” wrap, the cable length may be determined. The transition point identifies if the cable is long or short, at which point the optimum tuning parameters can accordingly be set. A calibration mechanism calibrates the high speed transmitter/receiver pair characteristics, and, thus, optimizes the transmission performance between subsystems. The calibration mechanism mitigates the need for frequent error correction and does not incur the performance degradation associated with error correction techniques.

Abstract: A mechanism is provided for discovering and isolating failure of high speed traces in a manufacturing environment. The mechanism utilizes transmit pre-emphasis and receiver equalization in combination with attenuated wrap plugs to enhance discovery and isolation of manufacturing defects in the manufacturing environment. The mechanism adjusts pre-emphasis and equalization in real time in high speed devices, allowing for much greater variation to compensate for design margins and specification variances. While the card is under test with wrap-backs installed, the pre-emphasis and receiver equalization are brought to the limits while logging the bit error rate to a non-volatile memory element. The mechanism then compares the bit error rate information to empirically derived signatures for failure isolation.

An abstraction manager enforces write atomicity and disallows options which are inconsistent with write atomicity. The abstraction manager constructs through a physical device interface a logical continuous view of a storage pool in a manner consistent with write atomicity. Applications collect information specific to write atomicity from the abstraction manager through an application interface.
