    Abstract: In some aspects, the techniques described herein relate to a method including receiving, from a host device, a first request to write first data to a memory device; adding the first request to a queue on the memory device; determining an availability of a write buffer of the memory device; retrieving the first data from the host device based on the determining and the first request added to the queue; and writing the first data to a write buffer of the memory device. The method may further include returning a completion message to the host device based on writing the first data to the write buffer; and writing the first data from the write buffer of the memory device to storage media. The first request may be an SQE, and the method may further include parsing the SQE and determining that the SQE is a write command.

    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.

    IPC: G06F12/02

    Abstract: Provided are systems, methods, and apparatuses for controlling write amplification factor in storage devices. The systems, devices, and methods include obtaining access to a storage device with a physical storage capacity, a logical storage capacity being mapped to the physical storage capacity, and an overprovisioning capacity being based on a ratio of the physical storage capacity. The systems, devices, and methods include assigning a first portion of the logical storage capacity to a first reclaim unit handle and a second portion of the logical storage capacity to a second reclaim unit handle, selecting the second reclaim unit handle to manage random write operations based on identifying the random write operations on the storage device, reducing, based on the selecting, the second portion of the logical storage capacity, and assigning, based on the selecting, an amount of the overprovisioning capacity to the second reclaim unit handle.

    Abstract: A storage device may include at least one storage medium and a controller configured to receive a write command, wherein the write command specifies data and a reclaim unit handle, receive information about the data, and store, based on the reclaim unit handle and the information, the data in a reclaim unit of the at least one storage medium. The information may include access information. The information may include error tolerance information. The information may include data attribute information. The information may include data type information. The controller may be configured to determine the information based, at least in part, on the reclaim unit handle. The controller may be configured to receive an indicator that may be separate from the reclaim unit handle, and determine the information based, at least in part, on the indicator.

    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.
