An apparatus, system, and method are disclosed for managing a cache. A cache interface module provides access to a plurality of virtual storage units of a solid-state storage device over a cache interface. At least one of the virtual storage units comprises a cache unit. A cache command module exchanges cache management information for the at least one cache unit with one or more cache clients over the cache interface. A cache management module manages the at least one cache unit based on the cache management information exchanged with the one or more cache clients.

A storage system implements a sparse, thinly provisioned logical-to-physical translation layer. The storage system may perform operations to modify logical-to-physical mappings, including creating, removing, and/or modifying any-to-any and/or many-to-one mappings between logical identifiers and stored data (logical manipulation operations). The storage system records persistent metadata to render the logical manipulation (LM) operations persistent and crash-safe. The storage system may provide access to LM functionality through a generalized LM interface. Clients may leverage the LM interface to efficiently implement higher-level functionality and/or offload LM operations to the storage system.

An atomic storage module may be configured to implement atomic storage operation directed to a first set of identifiers in reference to a second, different set of identifiers. In response to completing the atomic storage operation, the atomic storage module may move the corresponding data to the first, target set of identifiers. The move operation may comprise modifying a logical interface of the data. The move operation may further include storing persistent metadata configured to bind the data to the first set of identifiers.

A storage layer is configured to implement efficient open-close consistency operations. Open close consistency may comprise preserving the original state of a file until the file is closed. The storage layer may be configured to clone a file in response to a file open request. Cloning the file may comprise referencing file data by two separate sets of identifiers. One set may be configured to reflect file modifications, and the other set may be configured to preserve the original state of the file. Subsequent operations configured to modify the file may be performed in reference to one of the sets of identifiers, while the storage layer provides access to the unmodified file through the other set of identifiers. Closing the file may comprise merging the sets of identifiers according to a merge policy.

The system and method described herein for managing information technology models in an intelligent workload management system may include a computing environment having a model-driven, service-oriented architecture for creating collaborative threads to manage workloads. In particular, the management threads may converge information for managing planned changes and recovery processes for version-controlled snapshots of the information technology models. For example, a discovery engine may enrich models of an infrastructure with identity information obtained from an identity vault and the infrastructure itself, and a management infrastructure may then manage planned changes to the infrastructure model. In particular, the management infrastructure may construct implementation plans that coordinate interaction between managed entities to implement the planned changes, and may further detect drifts between operational states and planned states for the infrastructure models.

A customized distribution, e.g. of Linux software, is built using only packages that satisfy a customer's individual requirements. The packages are verified, at build time, to be interoperable at run-time. Also, the distribution is verified to ensure all package dependencies are included. In cases where no package already exists that meets a user requirements, a new package can be created for this purpose. The packages in the distribution customized for the user can be tracked, so that as updates to the packages are released, the customer can be notified about those updates (without being notified about packages not in the customer's customized distribution). Finally, once the distribution has been built for the user, it can then be offered as a general-purpose distribution for future customers.

System and method for performing processing functions on a warehoused service image. In one embodiment, the system comprises a service image warehouse for storing at least one service image; means for modifying the at least one service image by performing at least one of a plurality of service image processing functions on a service image contemporaneously with a user's checking the at least one service image out of the service image warehouse; means for checking the modified service image back into the service image warehouse; and a plurality of compute nodes connected to the service image warehouse to which the at least one service image may be deployed. Each of the compute nodes comprises one of a physical machine and a virtual machine host.

An apparatus, system, and method for application direct virtual memory management. The method includes detecting a system memory access to a virtual memory address within a monitored page of data not loaded in main memory of a computing system. The method includes determining a first swap address for a loaded page of data in the main memory. The first swap address is defined in a sparse virtual address space exposed by a persistent storage device. The first swap address is associated in an index with a first deterministic storage location. The index is managed by the persistent storage device. The method includes storing the loaded page on a persistent storage device at the first deterministic storage location. The method includes moving the monitored page from a second deterministic storage location to the main memory. The second deterministic storage location is associated with a second swap address in the index.

The system and method described herein for providing annotated service blueprints in an intelligent workload management system may include a computing environment having a model-driven, service-oriented architecture for creating collaborative threads to manage workloads. In particular, the management threads may converge information for creating annotated service blueprints to provision and manage tessellated services distributed within an information technology infrastructure. For example, in response to a request to provision a service, a service blueprint describing one or more virtual machines may be created. The service blueprint may then be annotated to apply various parameters to the virtual machines, and the annotated service blueprint may then be instantiated to orchestrate the virtual machines with the one or more parameters and deploy the orchestrated virtual machines on information technology resources allocated to host the requested service, thereby provisioning the requested service.
