Abstract: A server node can monitor the status of servers in a server cluster. The node may receive an alert indicating that a server in the server cluster is unavailable. In response to the alert, the node can send instructions that cause pending remote procedure call requests to be canceled and then reissued to another server in the server cluster instead of to the first server.

Abstract: A system and method of characterizing a logical storage object. Information associated with the logical storage object is stored. The information includes information characterizing quiesce capabilities and split characteristics for the logical storage object. That information is transmitted to a processor and is used to characterize the logical storage object.

Abstract: Techniques for implementing an adaptive data access error handling policy are disclosed. In one particular exemplary embodiment, the technique may be realized as a system comprising a shared storage device communicatively coupled to a network, and a computer cluster communicatively coupled to the network, the computer cluster comprising a plurality of nodes each mounting a shared file system thereon, a first node of the plurality of nodes to send a data access request to the shared storage device, to identify a data access error associated with the data access request, and to determine whether to permit access to the shared file system based on the data access error being a local data access error or a global data access error.

Abstract: A system for asynchronous reads of old data blocks updated through a write-back cache includes a storage device, a write-back cache, a storage consumer, a storage processing node, and device management software. The device management software may be configured to store a new version of a data block in the write-back cache in response to an update request from the first storage consumer and to then send an update completion notification to the first storage consumer. Some time after the update completion notification has been sent, the device management software may be configured to send a previous version of the updated data block to the storage processing node, where it may be required to perform an operation such as a copy-on write operation or a snapshot update.

Abstract: A system and method of identifying methods of quiescing a storage object. Data is received identifying the storage object and a freeze list is generated. The freeze list includes one or more freeze methods appropriate for quiescing the storage object. Generating includes creating a hierarchy of logical storage objects below the identified storage object, associating quiesce characteristics with each logical storage object below the identified storage object and generating freeze vectors as a function of quiesce characteristics associated with each logical storage object below the identified storage object.

Abstract: Methods, functional data, and systems for logically representing a storage environment are provided. A target storage environment having one or more storage data objects is mapped to a data structure. Any subsequent disparate or remote but similar storage environment has direct or indirect access to the data structure such that one or more of the data objects are permissibly directly/indirectly referenced or replicated within the disparate or remote but similar storage storage environment. Changes to the data structure are communicated, thereby ensuring the reliable use of the representation for the target storage environment.

Abstract: Methods and systems to access storage objects are provided. A reference to a storage object is used to determine a storage stack level associated with the reference. If the storage stack level is not the lowest level of a storage stack, then the reference is translated to a next stack level reference and passed through to a next stack level associated with the stack. References are translated and passed through iteratively until the lowest level of the stack is reached, wherein an absolute reference to the storage object is obtained and propagated back to an original referencing module, thereby providing access to the storage object.

Abstract: Methods, systems, and apparatus to interface with storage objects are provided. A storage object handle is provided on request and a storage object is mapped within a first storage environment. Further, a configuration identifier notifies client modules when the storage object's physical locations are altered in the first storage environment. API libraries provide client modules access to use the storage object, even when the client modules reside in a second storage environment.

Abstract: A system and method for controlling the creation of stable disk images. Data is transmitted to an application program interface identifying the storage object. The application program interface returns a list with one or more methods appropriate for quiescing or for freezing the storage object.

Abstract: A system and method for efficient file content searching within a file system. In one embodiment, the system may include a storage device configured to store data and a file system configured to manage access to the storage device. The file system may be configured to detect a search operation to determine the presence of a given data pattern within a first file stored on the storage device, and to store an indication of the given data pattern and an indication of result data of the search operation in a first record associated with the first file.
