Abstract: The method of the present invention to re-factor, rationalize, and prioritize a service model and to assess service exposure in the service model is illustrated. The service model is reviewed and re-factored and the service portfolio and service hierarchy are refined, exposure decisions are made, and finally the service model and its constituent parts are rationalized based on the re-factoring and exposure decisions. Another technique called Service Litmus Tests (SLTs) is leveraged during service re-factoring and rationalization. SLTs are set of gating criteria to select and filter a set of (candidate) services from the service portfolio for exposure. A Service Exposure Assessment Toolkit (SEAT) is also presented in the present invention. SEAT is a mathematical model to facilitate making exposure decisions for services and prioritizing the services in the service model.

Abstract: A Storage Area Network (SAN) system has host computers, front-end SAN controllers (FE_SAN) connected via a bus or network interconnect to back-end SAN controllers (BE_SAN), and physical disk drives connected via network interconnect to the BE_SANs to provide distributed high performance centrally managed storage. Described are hardware and software architectural solutions designed to eliminate I/O traffic bottlenecks, improve scalability, and reduce the overall cost of SAN systems. In an embodiment, the BE_SAN has firmware to recognize when, in order to support a multidisc volume, such as a RAID volume, it is configured to support, it requires access to a physical disk attached to a second BE_SAN; when such a reference is recognized it passes assess commands to the second BE_SAN. Further, the BE_SAN has firmware to make use of the physical disk attached to the second BE_SAN as a hot-spare for RAID operations.

Abstract: Described are memory modules that support dynamic point-to-point extensibility using fixed-width memory die. The memory modules include data-width translators that allow the modules to vary the effective width of their external memory interfaces without varying the width of the internal memory interfaces extending between the translators and associated fixed-width dies. The data-width translators use a data-mask signal to selectively prevent memory accesses to subsets of physical addresses. This data masking divides the physical address locations into two or more temporal subsets of the physical address locations, effectively increasing the number of uniquely addressable locations in a given module. Reading temporal addresses in write order can introduce undesirable read latency. Some embodiments reorder read data to reduce this latency.

Abstract: The direct memory access device and method of the present invention uses an event calendar, an expired event queue of a fixed size, a calendar scanner, and an event mover. The event calendar stores an event in a linked list. The expired event queue stores an event that has already expired from the event calendar. The calendar scanner automatically scans the event calendar without management by a central processing unit (CPU). The event mover moves an event from the event calendar to the expired event queue without management by the CPU. The method provides for storing the event in the linked list, automatically scanning the event calendar without management by the CPU, moving the event from the event calendar to an expired event queue of a fixed size without management by the CPU, and storing the event that has already expired from the event calendar.

Abstract: An apparatus, system, and method are disclosed for improved tracking of software item defects. The approach involves maintaining defect attributes for a particular software bug. Certain attributes are user-defined while others are derived. Attributes may be, for example, questions, requests for action, requests for approval, or others. The primary attributes and derived attributes for the bug are associated with users that are associated with the software bug, and a determination is made as to whether or not action is required by the individual users for the software bug using the attributes. If action is required, the user is alerted that action is required for the software bug. The actions and/or bugs may be presented to the user using an inbox format. The inbox may sort actions based on priority, what type of attribute is relevant to the user, or using other categorizations.

Abstract: Methods and apparatus for dynamic class reloading and versioning that allow developers to change and recompile classes and to have running programs adopt the new versions of the classes dynamically, without redeploying the application. A dynamic class reloading component detects if the environment supports dynamic class redefinition and uses it if supported but does not require it. As the component loads a managed class, it modifies the bytecode of the class and generates additional classes and interfaces to support type-safe class versioning. Unique names are generated for successive versions of a managed class. A separate interface may be generated for each distinct method name and signature implemented on managed classes. Each generated class may implement all the generated interfaces that correspond to its methods. The same class loader that would load each managed class without the component loads the component-generated classes and interfaces.

Abstract: Access management techniques have been developed to specify and facilitate mappings between I/O and host domains in ways that provide flexibility in the form, granularity and/or extent of mappings, attributes and access controls coded relative to a particular I/O domain. In some embodiments of the present invention, operation translations coded relative to a particular logical I/O device, domain or sub-window seek to optimize functionality, isolation or some other figure of merit without regard to needs or limitations of another. In this way, operation translations need not be uniform and need not reduce supported operation semantics to correspond to that of a lowest common denominator I/O device. In some embodiments, the form of mappings (e.g.
