    Abstract: A system and method for host provided address translation cache prepopulation. In some embodiments, the method includes: receiving, by a persistent storage device, a first address translation cache entry; receiving, by the persistent storage device, an input-output command; and executing the input-output command, by the persistent storage device, the executing of the input-output command including performing direct memory access of a memory location at an address calculated based on the input-output command and based on the first address translation cache entry.

    Abstract: Provided are systems, methods, and apparatuses for multitenancy SSD access control. In one or more examples, the systems, devices, and methods include determining capabilities of a storage device for supporting multitenancy based on a physical function message from the storage device, identifying a tenant of a host, the host being communicatively connected with the storage device, negotiating an access contract between the tenant and the storage device, where the negotiating includes sending an access descriptor of the tenant to the storage device, the access descriptor indicating a requested level of access to the storage device, receiving, from the storage device, an access grant based on the negotiating, the access grant including an access allocation for the tenant based on the access descriptor, and enabling the tenant to access the storage device based on configuring the tenant with a virtualized computing environment in accordance with the access allocation.

    Abstract: Inventive aspects include a device including storage media. The device includes a PMU, and a controller communicatively coupled to the PMU. The PMU determines that an operating power of the device exceeds a threshold, and transmits a signal to the controller to trigger a power reduction operation. The controller throttles one or more operations until the operating power goes below the threshold. Some embodiments include a method for controlling performance of a storage device. The method includes measuring, by a PMU, a power consumption associated with a storage device. The method includes determining, by the PMU, whether the power consumption is greater than a threshold. In response, the method may include setting a performance throttle. The method may include determining, by the PMU, whether the power consumption is less than the threshold. In response, the method may include releasing the performance throttle.

    Abstract: A method may include transferring data from a host to an encryption offload engine through an interconnect fabric, encrypting the data from the host at the encryption offload engine, and transferring the encrypted data from the encryption offload engine to a storage device through a peer-to-peer connection in the interconnect fabric. The method may further include transferring the encrypted data from the storage device to the encryption offload engine through a peer-to-peer connection in the interconnect fabric, decrypting the encrypted data from the storage device at the encryption offload engine, and transferring the decrypted data to the host through the interconnect fabric. The method may further include transferring the encrypted data from the storage device to the host, and verifying the encryption of the encrypted data at the host.
