Publication number: 20240143175Abstract: One or more aspects of the present disclosure relate to predicting one or more performance metrics of a storage array configuration. In embodiments, a storage array configuration can be generated based on one or more array-configuration related parameters. In addition, IO workload metrics corresponding to an IO workload received by an array corresponding to the storage array configuration can be recorded. Further, at least one response time (RT) prediction can be generated based on the IO workload metrics. Accordingly, another storage array configuration can be generated based on the RT predictions and according to performance requirements defined by a service level objective (SLO).Type: ApplicationFiled: October 28, 2022Publication date: May 2, 2024Applicant: Dell Products L.P.Inventors: Hagay Dagan, Ron Arnan, Gil Ratsaby

Patent number: 11366771Abstract: An apparatus comprises a host device configured to communicate over a network with a storage system. The host device comprises a plurality of host bus adaptors, and a multi-path input-output driver configured to control delivery of input-output operations from the host device to the storage system over selected ones of a plurality of paths through the network. The paths are associated with respective initiator-target pairs wherein each of the initiators comprises a corresponding one of the host bus adaptors and each of the targets comprises a corresponding one of a plurality of ports of the storage system. The host device monitors performance of the ports in processing input-output operations delivered thereto, detects an initiator-related condition based at least in part on the monitored performance, and automatically adjusts an assignment of one or more of the initiators to one or more of the targets based at least in part on the detected initiator-related condition.Type: GrantFiled: May 2, 2019Date of Patent: June 21, 2022Assignee: EMC IP Holding Company LLCInventors: Erik P.

Patent number: 11347414Abstract: Telemetry data gathered from active deployed SAN nodes is used to create a machine learning model that predicts storage system performance, e.g. in terms of response time. The telemetry data may be filtered to remove outlier values and less relevant information before creating the training dataset. Engineered features may be created that include types of data that are not present in the telemetry data. For example, data types from the telemetry data may be combined to create engineered features that are more relevant than the individual data types. The engineered features are included in the training dataset. The machine learning model may be used to test possible configurations for a planned SAN node based on expected workload and performance requirements. Outputted data may include satisfactory configurations for a planned storage system.Type: GrantFiled: October 24, 2019Date of Patent: May 31, 2022Assignee: Dell Products L.P.Inventors: Paulo Ferreira, Adriana Prado, Pablo Da Silva, Ron Arnan, Hagay Dagan, Adnan Sahin

Patent number: 11275766Abstract: A complex object generator is implemented, for example, as an integrated development environment. The complex object generator includes a hierarchical object relationship data structure describing classes of objects, relationships between the classes of objects, and metrics associated with the classes of objects. The hierarchical object relationship data structure is parsed by parser to create a hierarchy of Java classes. A user interface uses the hierarchy of Java classes to constrain selection of objects and metrics during creation of the complex object. As input is received relative to selected objects and metrics, the complex object is incrementally built. By constraining object and metric selection using the hierarchy of Java classes, the complex object is guaranteed to be valid when built, thus reducing or eliminating the number of errors associated with building complex objects.Type: GrantFiled: June 15, 2020Date of Patent: March 15, 2022Assignee: Dell Products, L.P.Inventors: Gil Ratsaby, Ron Arnan, Hagay Dagan

Patent number: 10019195Abstract: For each storage array in a storage system, a single value score indicative of the overall health of the respective storage array is calculated. Storage array health score may be tracked over time and used to identify storage arrays in need of maintenance. The storage array health score may be calculated as a composite of four component scores: physical component health, logical component health, Service Level Objective compliance and Best Practice Configuration Compliance. The physical component and logical component scores may be based on multiple different category health scores, and each category health score may be based on multiple instance health scores. Health scores may be used to identify remedial actions and predict health score increase as a result of remedial actions.Type: GrantFiled: June 27, 2016Date of Patent: July 10, 2018Assignee: EMC IP HOLDINGS COMPANY LLCInventors: Fatemeh Azmandian, Ron Arnan, Amnon Naamad, David Moloney

Patent number: 8498968Abstract: A data management and archive method and apparatus, for implementation in an automated system to monitor and manage status, performance and configuration data for networked storage components. Analysis and cross-correlation of data related to the storage components can be done individually, collectively and/or comparatively. A collection manager component of a workload analyzer is implemented to start and stop data collection. The collection manager includes a command and control module that coordinates requests of data from at least one collection agent configured on at least one host connected to the storage component(s). The collection manager manages collection of data and effects file transfer of collected data according to a user specified policy, and maintains status of the data collected. The user specified policy allows the user to specify data collection “shifts” (i.e. periodicity).Type: GrantFiled: October 28, 2011Date of Patent: July 30, 2013Assignee: EMC CorporationInventors: William Zahavi, Lee W.

Patent number: 8060759Abstract: Described is a storage system and method for managing and optimizing power consumption in a storage system. Logical devices are mapped to physical disk drives. A plurality of power profiles is defined. Each power profile is associated with a mode of operation for a physical disk drive. One of the power profiles is assigned to each logical device. One of the physical disk drives is identified for which every logical device mapped to that physical disk drive has been assigned the same power profile. The identified physical disk drive is operated in the mode of operation associated with said same power profile. The mapping of the logical devices to the physical disk drives may be changed in order to group logical devices assigned the same power profile onto the same physical disk drive.Type: GrantFiled: June 29, 2007Date of Patent: November 15, 2011Assignee: EMC CorporationInventors: Ron Arnan, Thomas E.

Patent number: 7873835Abstract: Restricting access to a device includes obtaining a passphrase for a user, obtaining access credentials for the user, obtaining a PIN value for the user, one-way encrypting at least the access credentials and the PIN using a secret key provided with the device. The user is allowed access to the device if the result of one-way encrypting equals the passphrase. The user is denied access to the device if the result of one-way encrypting does not equal the passphrase. The device may be a storage device. The access credentials may include a username that identifies the user and may include a role for the user. The access credentials may include a time period for which access is allowed. Access may be subsequently revoked in response to the current date and time being greater than the time period for which access is allowed.Type: GrantFiled: March 31, 2006Date of Patent: January 18, 2011Assignee: EMC CorporationInventors: Yedidia Atzmony, David J.
