  • Publication number: 20220164104
    Abstract: 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.

  • Patent number: 11343198
    Abstract: Provided are systems and methods for reliable, out-of-order transmission of packets. In some implementations, provided is an apparatus configured to communicate with a network and a host device. The apparatus may receive messages from the host device at a send queue, where each message includes destination information. The apparatus may further determine, using the destination information and an identify of the send queue, a transport context associated with a destination on the network. The apparatus may further, for each message and using the transport context, generate a packet including the message and transmit the packet over the network. The apparatus may further monitor status for each transmitted packet.

  • Patent number: 11281967
    Abstract: An integrated circuit is configurable to generate a notification message when an indicator of an event used to synchronize the execution of different functional blocks of the integrated circuit changes status. The indicator of the event is cleared when an operation is triggered and is set when the operation completes. The notification message includes a timestamp indicating the time when the indicator of the event changes status. The notification message is used to determine the execution timeline of a set of instructions executed by integrated circuit and to identify bottlenecks in the set of instructions or the integrated circuit.

  • Patent number: 11275503
    Abstract: Methods and apparatus are disclosed for securely erasing partitions of reconfigurable logic devices such as FPGAs in a multi-tenant server environment. In one example, a method of securely erasing an FPGA includes identifying one partition of previously-programmed resources in the FPGA, erasing the identified partition by storing new values in memory or storage elements of the identified partition, and storing new values in memory or storage elements of additional external resources electrically connected to the integrated circuit and associated with the identified partition. Thus, other partitions and subsequent users of the identified partition are prevented from accessing the securely erased data. A configuration circuit, accessible by a host computer via DMA, can be programmed into the FPGA reconfigurable logic for performing the disclosed erasing operations.

  • Publication number: 20220035766
    Abstract: A technique for remote direct memory access (RDMA) may include receiving a packet that was sent over a network, and determining the packet has metadata used for queue selection. The technique may also include selecting a queue based on the metadata, and writing the data of the packet to an application memory using the datapath associated with the selected queue. Amended metadata can be generated to indicate that the data has been written to the application memory, and the amended metadata can be stored in a software accessible buffer.

  • Publication number: 20210397346
    Abstract: Technologies are provided for dynamically changing a size of a cache region of a storage device. A storage device controller writes data to the cache region of the storage device using a particular storage format. The storage device controller then migrates the cached data to a storage region of the device, where the data is written using a different storage format. A dynamic cache manager monitors input and output activity for the storage device and dynamically adjusts a size of the cache region to adapt to changes in the input and/or output activity. The dynamic cache manager can also adjust a size of the storage region. The storage device controller can automatically detect that the storage device has dynamic cache support and configure the storage device by creating the cache region and the storage region on the device.
