Patent number: 11868617Abstract: A peripheral device may implement storage virtualization for non-volatile storage devices connected to the peripheral device. A host system connected to the peripheral device may host one or multiple virtual machines. The peripheral device may implement different virtual interfaces for the virtual machines or the host system that present a storage partition at a non-volatile storage device to the virtual machine or host system for storage. Access requests from the virtual machines or host system are directed to the respective virtual interface at the peripheral device. The peripheral device may perform data encryption or decryption, or may perform throttling of access requests. The peripheral device may generate and send physical access requests to perform the access requests received via the virtual interfaces to the non-volatile storage devices. Completion of the access requests may be indicated to the virtual machines via the virtual interfaces.Type: GrantFiled: February 11, 2022Date of Patent: January 9, 2024Assignee: Amazon Technologies, Inc.Inventors: Raviprasad Venkatesha Murthy Mummidi, Matthew Shawn Wilson, Anthony Nicholas Liguori, Nafea Bshara, Saar Gross, Jaspal Kohli

Patent number: 11258796Abstract: A key-value store supporting GET, PUT and DELETE operations, serializes multiple clients using two locks, and that supports asynchronous resizing. The locking scheme includes an operation of holding two locks, one for the key involved in the operation, one for the page currently searched or updated. The store can either be a single volume holding keys and data or can be organized as a directory volume referencing a number of data volumes organized by data-size ranges. The scheme also supports asynchronous resizing of the directory while continuing to perform operations.Type: GrantFiled: July 5, 2019Date of Patent: February 22, 2022Assignee: Fungible, Inc.Inventors: Jaspal Kohli, Bertrand Serlet, Xiaoqin Ma, Daniel James Nigel Picken

Patent number: 10949303Abstract: Techniques are described in which network devices, such as one or more data center access nodes, are configured to support durable block storage with inline erasure coding, i.e., erasure coding in real time as data is updated. A Durable Block Device (DBD) supports a block level API for one or more storage volumes that may be mapped to one or more applications executed by servers in communication with the data center access nodes. The disclosure describes the operation of the data plane of the DBD that is hosted on one or more access nodes, and its interactions with the management and control planes of the DBD that are hosted on one or more of the servers.
