The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method for handling storage in a virtualization environment including identifying a situation in which a storage controller ownership change is to occur for a virtual disk, identifying a candidate replacement owner for the virtual disk and transferring ownership of the virtual disk to the candidate replacement owner.“

The patent application was filed on January 18, 2013 (13/744,668).

Architecture for managing I/O and storage for virtualization environment
Nutanix, Inc., San Jose, CA, has been assigned a patent (9,256,456) developed by Aron, Mohit, Los Altos, CA, for a “architecture for managing I/O and storage for a virtualization environment.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Disclosed is an improved approach to implement I/O and storage device management in a virtualization environment. According to some approaches, a Service VM is employed to control and manage any type of storage device, including directly attached storage in addition to networked and cloud storage. The Service VM implements the Storage Controller logic in the user space, and can be migrated as needed from one node to another. IP-based requests are used to send I/O request to the Service VMs. The Service VM can directly implement storage and I/O optimizations within the direct data access path, without the need for add-on products.“

The patent application was filed on October 14, 2014 (14/514,326).

Metadata for managing I/O and storage for virtualization environment
Nutanix, Inc., San Jose, CA, has been assigned a patent (9,256,374) developed by Aron, Mohit, Los Altos, CA, Bhardwaj, Rishi, and Guturi, Venkata Ranga Radhanikanth, San Jose, CA, for a “metadata for managing I/O and storage for a virtualization environment.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Disclosed is an improved approach for using advanced metadata to implement an architecture for managing I/O operations and storage devices for a virtualization environment. According to some embodiments, a Service VM is employed to control and manage any type of storage device, including directly attached storage in addition to networked and cloud storage. The advanced metadata is used to track data within the storage devices. A lock-free approach is implemented in some embodiments to access and modify the metadata.“

The patent application was filed on September 29, 2014 (14/500,730).
