A method, computer program product, and computing system for determining a queue depth and a flush rate for each of a plurality of pending data queues associated with a cache system, thus defining a queue depth/flush rate pair for each of the plurality of pending data queues. A predicted drain time is determined for each of the plurality of pending data queues based, at least in part, upon the queue depth/flush rate pair, thus defining a plurality of predicted drain times that are respectively associated with the plurality of pending data queues.

Cache management system and method

Methods for organizing data. The methods may comprise the step of receiving a write request comprising a data unit. The methods may also comprise the steps of organizing the data unit into a sub-file and incorporating the sub-file into a data file according to a log-structured organization system. In addition, the methods may include the step of writing the data file to a data storage according to a second organization system.

Systems and methods for arbitrary data transformations

Methods of managing access to at least one resource in a computer system. The methods may comprise the step of associating access rights with an application resource. The access rights may define a level of access to the resource granted to the application. The methods may also comprise the step of digitally signing the access rights and the application resource. In various embodiments, the associating may comprise incorporating the access rights into a stream of a file including the application resource. Also, in various embodiments, the associating may comprise incorporating the access rights into an extended attribute of a file including the application resource.

Managing access to a resource

Methods of managing application resources in a computer system. The methods may comprise the steps of determining a configuration of the computer system and receiving a request to access an application resource. The methods may also comprise the step of directing the request to a data file. The data file may include a plurality of streams, and each of the plurality of streams may comprise a configuration-specific version of the application resource. In various embodiments, the methods may also comprise the step of directing the request to a first stream of the plurality of streams. The first stream may comprise version of the application resource specific to the configuration. Various system embodiments are also provided.

Managing application resources

Methods of monitoring a computer system. The methods may comprise the steps of calculating a first checksum of a data location and receiving a request from an operation running on the computer system for a lock corresponding to the data location. The methods may also comprise the steps of calculating a second checksum of the data location, and generating an indication if the first checksum and the second checksum are not equivalent. Also, methods of detecting a lock ranking violation in a computer system. The methods may comprise the steps of receiving a request from an operation for a first lock associated with a first data storage location and reviewing a list of locks issued to the operation. The methods may also comprise the step of determining whether the operation possesses a lock ranked higher than the first lock.
