In one embodiment, a system comprises a host processor and a storage system. The storage system comprises one or more storage devices, and each storage device comprises a non-volatile memory and a compute offload controller. The non-volatile memory stores data, and the compute offload controller performs compute tasks on the data based on compute offload commands from the host processor.

Computational data storage systems

Techniques for storage and processing for distributed file systems are disclosed. In the illustrative embodiment, padding is placed between data elements in a file to be stored on a distributed file system. The file is to be split into several objects in order to be stored in the distributed file system, and the padding is used to prevent a data element from being split across two different objects. The objects are stored on data nodes, which analyze the objects to determine which data elements are present in the object as well at the location of those objects. The location of the objects is saved on the data storage device, and those locations can be used to perform queries on the data elements in the object on the data storage device itself. Such an approach can reduce transfer of data elements from data storage to local memory of the data node.

Technologies for storage and processing for distributed file systems

The disclosure is related to storage devices employing file-aware drivers. In one example, a device may comprise a driver configured to retrieve file system information related to an input/output (I/O) command, determine storage attributes based on the file system information, and store selected data in a preferred region of a data storage medium based on the storage attributes. Another embodiment may be a method comprising inspecting characteristics of an I/O request for a file, setting storage attributes for the file based on if the file is preferred, and storing the file on a data storage medium based on the storage attributes.

Smart file location

The disclosure is related to file-aware caching for data storage devices. In one example, a device may comprise a data storage medium, an interface circuit to communicate with a host, and a driver configured to retrieve file system information related to a structured input/output (I/O) command from the host, and select caching attributes based on the file system information. Further, a system may include a host and at least one driver operating on the host; the driver configured to intercept a I/O request initiated at the host, obtain operating system information from the host about the I/O request, and store the operating system information that it is accessible to a data storage device to allow the data storage device to implement caching attributes based on the operating system information.

File-aware caching driver

Examples may include a storage device coupled to a host bus adapter and a SATA controller over a SATA interface. The storage device includes a memory and a storage device controller. The storage device controller includes a collision detector and counter component to detect and count collisions on the SATA interface for a period of time; and a bus limiter component to detect a type of workload on the SATA interface, and when the detected workload is only read commands and a number of detected collisions is less than a detected collision threshold during the period of time, to set a limit on a maximum number of commands sent by the host bus adapter to the storage device controller over the SATA interface.

Read performance on a SATA storage device behind a host bus adapter

The disclosure is related to systems, devices, and methods for file-aware priority drivers in data storage devices. In one example, a device may comprise a data storage medium, an interface circuit to communicate with a host, a driver configured to retrieve file system information related to a structured input/output (I/O) command from the host, select priority attributes based on the file system information, and prioritize execution of the I/O command based on the priority attributes. Another embodiment may be a method comprising inspecting characteristics of an I/O request, choosing priority attributes for the I/O request based on the characteristics, and executing operations in an order based on the priority attributes.

File-aware priority driver

Systems and methods are disclosed for intelligent data caching behavior. In an embodiment, a method may comprise receiving a read or write command for specific data, determining related data associated with the specific data, and directing the related data be stored to a cache. In another embodiment, a system may comprise a host device, and at least one driver operating on the host device. The at least one driver may be configured to intercept read or write command from the host device to a data storage device regarding specific data, obtain information from the host device to determine associated data related to the specific data, and direct the data storage device to store the associated data to a cache memory.

File associated pinning

Systems and methods are disclosed for intelligent data caching behavior. In an embodiment, a method may comprise receiving an indication a user has selected specific data for caching, and storing the specific data to a cache memory. In another embodiment, a system may comprise a host device including a driver configured to monitor the system for an indication a user has selected specific data for caching, and store the specific data to a cache memory. In yet another embodiment, an apparatus may a data storage device including a nonvolatile data storage medium, a cache memory, and a processor. The Processor may be configured to receive an indication a user has selected specific data for caching, and copy the specific data form the nonvolatile data storage medium to the cache memory.

User selectable caching

The disclosure is related to data storage devices employing file-aware drivers. In one example, a device may comprise a driver configured to retrieve file system information related to an input/output (I/O) command, select priority attributes identifying whether the I/O command originated from a user-level application based on the file system information, and prioritize execution of the I/O command based on the priority attributes. Another embodiment may be a method comprising inspecting characteristics of a data input/output (I/O) request, choosing priority attributes for the I/O request based on the characteristics and a program initiating the I/O request, and executing operations in an order based on the priority attributes.
