Patent number: 9465671Abstract: Systems and methods relate to indexing of performance and cost of workloads in a computing environment. The computing environment may include a virtualized computing environment. According to some embodiments, a performance index relating to a plurality of workloads executing in the computing environment may be generated, where the performance index is based at least in part on performance and cost of use of one or more resources in the computing environment by the plurality of workloads. The index may be normalized. If the performance or cost of a particular workload departs from an expected performance or cost determined from the average performance and/or cost in the computing environment, resources may be reallocated to the workloads such that the performance or cost of the workload is closer to its expected performance or cost based on the performance index.Type: GrantFiled: August 24, 2012Date of Patent: October 11, 2016Assignee: Dell Software Inc.Inventor: Philip Eric Jackson

Patent number: 9465642Abstract: Embodiments of systems and methods are described for instant provisioning (e.g., cloning, copying, replicating, migrating, backing up, restoring, etc.) of virtual machines, virtual machine files, or other types of files (e.g., database files). In some implementations, a cloned virtual machine file can present an illusion to multiple applications accessing the cloned file that the cloned file contains all the appropriate data (e.g., a file system volume), even while the clone file is still being filled with relevant data. In some embodiments, the systems and methods use a file system filter driver to intercept and redirect certain input/output (I/O) requests to the cloned file. The file system filter driver may use a data structure (e.g., a bitmap) to determine which logical units of the clone file have already been filled with data. In some embodiments, the systems and methods use the operating system to handle cached I/O requests, which may improve efficiency.Type: GrantFiled: March 30, 2015Date of Patent: October 11, 2016Assignee: Dell Software Inc.Inventor: Dilip Chhotubhai Naik

Patent number: 9462012Abstract: Techniques for notification of reassembly-free file scanning are described herein. According to one embodiment, a first request for accessing a document provided by a remote node is received from a client. In response to the first request, it is determined whether a second request previously for accessing the document of the remote node indicates that the requested document from the remote node contains offensive data. If the requested document contains offensive data, a message is returned to the client, without accessing the requested document of the remote node, indicating that the requested document is not delivered to the client.Type: GrantFiled: September 2, 2014Date of Patent: October 4, 2016Assignee: DELL SOFTWARE INC.Inventors: Aleksandr Dubrovsky, Igor Korsunsky, Roman Yanovsky, Boris Yanovsky

Patent number: 9438577Abstract: A scalable access filter that is used together with others like it in a virtual private network to control access by users at clients in the network to information resources provided by servers in the network. Each access filter uses a local copy of an access control data base to determine whether an access request is made by a user. Each user belongs to one or more user groups and each information resource belongs to one or more information sets. Access is permitted or denied according to access policies which define access in terms of the user groups and information sets. The first access filter in the path performs the access check, encrypts and authenticates the request; the other access filters in the path do not repeat the access check. The interface used by applications to determine whether a user has access to an entity is now an SQL entity. The policy server assembles the information needed for the response to the query from various information sources, including source external to the policy server.Type: GrantFiled: August 14, 2013Date of Patent: September 6, 2016Assignee: Dell Software Inc.Inventors: Clifford Lee Hannel, Anthony May

Publication number: 20160224556Abstract: A system, method, and computer-readable medium for performing a predictive caching operation in which a hit rate is improved by pre executing statements that are predicted based upon previous use patterns. More specifically, by analyzing a stream of statements provided to a server, such as a database server, patterns of usage are detected and based upon these patterns, statements provided to the server are executed before the actual application executes the predicted statements. Thus the application executes faster because the data requested is already cached based upon the predictive execution.Type: ApplicationFiled: January 30, 2015Publication date: August 4, 2016Applicant: DELL SOFTWARE, INC.Inventors: Daniel T. Wood, Jan Henrik Jonsson
