  • Patent number: 11966632
    Abstract: Methods, systems, and devices are described to indicate, in an entry of logical to physical (L2P) mapping information stored at a host system, whether data associated with the entry is sequential to other data associated with a next entry or a previous entry. Each entry may have a third field, which may indicate whether the data is sequential. Based on the third field, the host system may determine whether data to be read from a memory system is sequential. The host system may transmit one read command to the memory system if the data is sequential, where the read command may include at least a portion of an L2P entry associated with the data. Similarly, based on the third field, the memory system may determine whether the data to be read is sequential, and may read additional, sequential data if the memory system determines that the data is sequential.

  • Patent number: 11916891
    Abstract: The techniques herein are directed generally to a “zero-knowledge” data management network. Users are able to share verifiable proof of data and/or identity information, and businesses are able to request, consume, and act on the data—all without a data storage server or those businesses ever seeing or having access to the raw sensitive information (where server-stored data is viewable only by the intended recipients, which may even be selected after storage). In one embodiment, source data is encrypted with a source encryption key (e.g., source public key), with a rekeying key being an encrypting combination of a source decryption key (e.g., source private key) and a recipient's public key. Without being able to decrypt the data, the storage server can use the rekeying key to re-encrypt the source data with the recipient's public key, to then be decrypted only by the corresponding recipient using its private key, accordingly.

  • Patent number: 11853807
    Abstract: Generally described, one or more aspects of the present application relate to scaling a cluster of compute capacity used to execute containerized applications or tasks. For example, a waiting area can be maintained, in which tasks that are requested to be executed in a cluster but are not able to be accommodated in the cluster due to the cluster not having sufficient compute capacity usable to execute such tasks are stored. The scaling of the cluster can be performed based on the characteristics of the tasks in the waiting area, such that the cost associated with adding too much compute capacity to the cluster can be reduced, while also reducing the time it takes to reach the desired level of compute capacity that can accommodate all of the requested tasks.

  • Patent number: 11770449
    Abstract: InfiniBand transport protocol today supports RDMA operations such as read and write with each operation having an opcode defined in the InfiniBand standard. Currently, new RDMA operations require extending the transport protocol by defining a new opcode, its respective header and enhancing InfiniBand implementations to support this new behavior. A more robust way of extending RDMA without requiring an expanding set of opcodes is to register computer code by associating it with a code key similar to a memory key. An InfiniBand channel adapter receiving an RDMA request that includes a code key executes the associated computer code, perhaps compiling it first, in response to receiving the RDMA request. The RDMA response returned to the requester includes an execution result indicating an outcome of executing the executable computer code.

  • Patent number: 11704057
    Abstract: A write request comprising a logical address, a payload, and an indicator reflecting the character of the payload is received from an application. Based on the indicator, a value of a parameter associated with storing the payload on one or more of a plurality of memory devices is identified. The value of the parameter is determined to satisfy a criterion associated with a particular memory device of the plurality of memory devices. The payload is stored on the particular memory device.

  • Patent number: 11687144
    Abstract: A new approach contemplates systems and methods to support control of power consumption of a memory on a chip by throttling port access requests to the memory via a memory arbiter based on a one or more programmable parameters. The memory arbiter is configured to restrict the number of ports being used to access the memory at the same time to be less than the available ports of the memory, thereby enabling adaptive power control of the chip. Two port throttling schemes are enabled—strict port throttling, which throttles the number of ports granted for memory access to be no more than a user-configured maximum throttle port number, and leaky bucket port throttling, which throttles the number of ports granted for the memory access down to be within a range based on a number of credit tokens maintained in a credit register.

  • Patent number: 11656589
    Abstract: Various embodiments of the present technology generally relate to power topology discovery in industrial environments. More specifically, some embodiments relate to automatic power topology discovery for factories based on device data that is already recorded for other purposes. Systems and methods described herein may be used to generate an accurate electrical network topology by collecting power data from power devices that may provide real-time or recorded measurements, detecting power change events, and matching power change signatures over power events for the devices in order to calculate the likelihoods of possible topology assumptions. Power change event data is used to recursively update topology probabilities using the Bayesian formula until a system topology can be produced with satisfactory confidence.

  • Patent number: 11645103
    Abstract: A method for securing the movement of virtual machines (VMs) between hosts. The method includes obtaining a first VM movement request; in response to obtaining the first VM movement request, identifying a first VM of the VMs and a first targeted host of the hosts associated with the first VM movement request using VM metadata and host metadata; making a first determination that the first targeted host is registered; in response to making the first determination, initiating the movement of the first VM to the first targeted host; and initiating, after the movement of the first VM, encryption of communication between the first VM and the first targeted host.

  • Patent number: 11641276
    Abstract: The present disclosure generally relates to effective key management by properly matching keys used for encryption to data that needs to be decrypted after receiving instructions to change or delete keys. By matching the actual key, rather than just a key index, to a command, each command will use the correct key throughout the entire life-span of the command, even if the key is switched or deleted prior to servicing the command. To implement the key management, a snapshot of the doorbell database is taken. All pending commands that are in the snapshot are then fetched prior to updating a key database with either the change or deletion of the key. After fetching of all pending commands from the snapshot and ensuring the keys are stored in a command context, the key database is updated.

  • Patent number: 11587641
    Abstract: A fuse fault repair circuit includes a fuse array, a signal storage module, and a scan repair module. The fuse array includes a redundant fuse array and a non-redundant fuse array. When the fuse array is not faulty, the redundant fuse array has no signal output, and the non-redundant fuse array outputs S first logic signals. Each storage unit in the signal storage module is configured to store a first logic signal sent by one fuse unit connected thereto. The scan repair module is configured to scan the storage units in the signal storage module, determine, when a faulty storage unit is scanned, that a first fuse unit connected to the faulty storage unit is faulty, and replace the first fuse unit with a first redundant fuse unit corresponding to the first fuse unit. The first logic signal corresponding to the first redundant fuse unit is a normal signal.
