Patent number: 10887176Abstract: In some examples, a method can involve collecting resource consumption data for resource consumer objects associated with hosts in a computing environment. The method can involve identifying, for each respective host, a respective set of resource consumer objects at the host and, based on the resource consumption data, determining a projected resource consumption history for each host, the projected resource consumption history being based on a combined resource consumption, over a period of time, associated with the respective set of resource consumer objects currently hosted a the host. The method can involve calculating a projected resource availability for each host based on a respective resource capability of the host and the projected resource consumption history for the host, and selecting a particular host for a resource consumer object based on the projected resource availability of each host.Type: GrantFiled: March 30, 2017Date of Patent: January 5, 2021Assignee: Hewlett Packard Enterprise Development LPInventors: Marty Fitzgerald, Jiri Schindler

Patent number: 9542281Abstract: Systems and methods herein obtain snapshots of one or more applications, while having minimal impact on performance of the applications. Embodiments may involve obtaining snapshots of modified application data within a node without disturbing the operations of the application. Systems may be configured to leverage the fast characteristics of local storage devices while utilizing the advantages provided by the remote storage of data. One or more applications may be preconfigured to record data modifications in one or more associated application state storages located on local memory. Further, one or more systems may operate in the background to identify modifications made to the associated application state storages and to determine an appropriate moment to take one or more snapshots of the stored data and transfer the one or more snapshots to one or more remote locations to be stored. Several factors may be used to determine when an appropriate moment has occurred.Type: GrantFiled: September 17, 2013Date of Patent: January 10, 2017Assignee: NETAPP, INC.Inventors: Jiri Schindler, Stephen M.

Patent number: 9477553Abstract: A storage system provides highly flexible data layouts that can be tailored based on reliability considerations. The system allocates reliability values to logical containers at an upper logical level of the system based, for example, on objectives established by reliability SLOs. Based on the reliability value, the system identifies a specific parity group from a lower physical storage level of the system for storing data corresponding to the logical container. After selecting a parity group, the system allocates the data to physical storage blocks within the parity group. In embodiments, the system attaches the reliability value information to the parity group and the physical storage units storing the data. In this manner, the underlying physical layer has a semantic understanding of reliability considerations related to the data stored at the logical level.Type: GrantFiled: January 23, 2014Date of Patent: October 25, 2016Assignee: NetApp, Inc.Inventors: Mark Walter Storer, Jiri Schindler

Patent number: 9424133Abstract: Systems and methods which provide for obtaining snapshots of one or more nodes, while having minimal impact on performance and throughput of the storage network are provided. Embodiments may involve a method of obtaining snapshots of individual node data within a clustered storage network having a plurality of nodes without requiring quiescing of every node. The snapshots may be obtained in a rolling fashion, e.g., moving across the individual nodes of a cluster either sequentially or non-sequentially. In other embodiments snapshots may be obtained in an asynchronous manner. The obtained snapshots then collectively define an eventually consistent view of the entire system. Such a view may be utilized to provide for mirroring functionality, e.g. to provide for DR and/or HA capabilities.Type: GrantFiled: July 10, 2013Date of Patent: August 23, 2016Assignee: NETAPP, INC.Inventor: Jiri Schindler

Patent number: 8825963Abstract: A storage system provides highly flexible data layouts that can be tailored to various different applications and use cases. The system dynamically balances performance with block sharing, based on service level objectives (SLOs). The system defines several types of data containers, including “regions”, “logical extents” and “slabs”. Each region includes one or more logical extents. Allocated to each logical extent is at least part of one or more slabs allocated to the region that includes the extent. Each slab is a set of blocks of storage from one or more physical storage devices. The slabs can be defined from a heterogeneous pool of physical storage. The system also maintains multiple “volumes” above the region layer. Each volume includes one or more logical extents from one or more regions. Layouts of the extents within the regions are not visible to any of the volumes.Type: GrantFiled: April 15, 2013Date of Patent: September 2, 2014Assignee: NetApp, Inc.Inventors: John K. Edwards, Keith A. Smith, Jiri Schindler, Steven R. Kleiman

Patent number: 8621176Abstract: A system and method for allocating data objects across multiple physical storage devices in a mass storage subsystem first determines a set of physical properties associated with the physical storage devices. The system assigns portions of the mass storage subsystem to a first division or a second division based on the physical properties, such that read operations directed to logically related data stored in the first division can be executed more efficiently than read operations directed to data stored in the second division. During operation, the system stores data objects with a low SLR in the second division, which may be allocated according to any well-known file system. If a write request is for a new data object with a high SLR, the system stores the new data object in a set of neighboring primary data chunks in the first division.Type: GrantFiled: January 20, 2010Date of Patent: December 31, 2013Assignee: NetApp, Inc.Inventor: Jiri Schindler

Patent number: 8489559Abstract: In one embodiment of the invention, a utility may be installed (e.g., by a system administrator) on a storage system. The utility may read content units on the storage system that are stored in one data format, and convert the content units to a second data format. In one embodiment, in response to a read request for a content unit, a data format in which to return the content unit may be selected and the content unit may be returned in that data format. In another embodiment, mapping information may be created that specifies in which data format a content unit should be returned in response to a request for the content unit. The mapping information may be stored either on the storage system that stores the content unit, the computer requesting access to the content unit, or any other computer or device in the computer system.Type: GrantFiled: July 20, 2010Date of Patent: July 16, 2013Assignee: EMC CorporationInventors: Kaleb Keithley, Jiri Schindler, Jonathan B Hall, Michael Kilian, Stephen J.
