Patent number: 10761735Abstract: An embodiment of the invention provides a method comprising: permitting an application to be aware to be aware of a distribution of a data of the application across a cache and a permanent storage device. The cache comprises a solid state device and the permanent storage device comprises a disk or a memory. In yet another embodiment of the invention, an apparatus comprises: a caching application program interface configured to permit an application to be aware to be aware of a distribution of a data of the application across a cache and a permanent storage device. A caching application program interface is configured to determine an input/output strategy to consume the data based on the distribution of the data.Type: GrantFiled: December 4, 2018Date of Patent: September 1, 2020Assignee: PrimaryIO, Inc.Inventors: Sumit Kumar, Sumit Kapoor

Patent number: 10656839Abstract: In an embodiment of the invention, a method comprises: recording application-level heuristics and IO-level (input/output-level) heuristics; correlating and analyzing the application-level heuristics and IO-level heuristics; and based on an analysis and correlation of the application-level heuristics and IO-level heuristics, generating a policy for achieving optimal application performance. In another embodiment of the invention, an apparatus comprises: a system configured to record application-level heuristics and IO-level heuristics, to correlate and analyze the application-level heuristics and IO-level heuristics, and based on an analysis and correlation of the application-level heuristics and IO-level heuristics, to generate a policy for achieving optimal application performance.Type: GrantFiled: November 19, 2018Date of Patent: May 19, 2020Assignee: PrimaryIO, Inc.Inventor: Murali Nagaraj

Patent number: 9792057Abstract: An embodiment of the invention provides an apparatus comprising: a hypervisor comprising a virtual caching appliance (VCA) and an intermediate multipathing module that interfaces with VCA; wherein the intermediate multipathing module is configured to pass an I/O request from a virtual machine to the VCA; and wherein the VCA is configured to determine if the I/O request is to be passed from the VCA to a solid state storage or if the I/O request is to be passed from the VCA to a hard disk storage. Another embodiment of the invention provides a method comprising: passing an I/O request from a virtual machine to a virtual caching appliance (VCA) in a hypervisor; and determining if the I/O request is to be passed from the VCA to a solid state storage or if the I/O request is to be passed from the VCA to a hard disk storage.Type: GrantFiled: September 23, 2015Date of Patent: October 17, 2017Assignee: PrimaryIO, Inc.Inventors: Harish Chandra Pujari, Anand Mitra, Dilip Madhusudan Ranade, Prasad Gajanan Joshi

Patent number: 9645901Abstract: An embodiment of the invention provides a method comprising: performing an application write; storing the application write in a local cache; performing a system call to request an underlying storage system to persist any application writes that are not yet persisted; and in response to the system call, copying the application write in the cache to a shared permanent storage. In another embodiment of the invention, an apparatus comprises: an application configured to perform an application write; a cache software configured to store the application write in a local cache; wherein the application is configured to perform a system call to request an underlying storage system to persist any application writes that are not yet persisted; and in response to the system call, the cache software is configured to copy the application write in the cache to a shared permanent storage.Type: GrantFiled: March 17, 2015Date of Patent: May 9, 2017Assignee: PrimaryIO, Inc.Inventor: Murali Nagaraj
