  • SYSTEMS AND METHODS FOR FAIL-SAFE OPERATIONS OF STORAGE DEVICES
    Publication number: 20200012624
    Abstract: Techniques for enabling fail-safe operations of storage devices are described. A device may be configured to delete an inode in a failsafe manner. A device may be configured to mark directory entries as not in use and ensure this goes to disk before anything else. A device may be configured to create an inode in a failsafe manner. A device may be configured to allocate and initialize a cluster and ensure this is written to disk before anything else. In this manner, a volume may be in a predictable state upon a failure occurring.

  • Systems and methods for enabling modifications of multiple data objects within a file system volume
    Patent number: 10496607
    Abstract: A device may be configured to perform techniques that enable may be used to allocate allocation units within a file system volume to data objects in a parallel manner. A file system driver may be configured to perform allocation operations based on an allocation mapping structure being logically partitioned into one or more of windows. Each window may be able to be lock independently during allocation operations. Window metadata may be used to evaluate windows of an allocation mapping structure.

  • SYSTEMS AND METHODS FOR STORING LARGE FILES USING FILE ALLOCATION TABLE BASED FILE SYSTEMS
    Publication number: 20180137136
    Abstract: This disclosure describes techniques for storing large files to file system volumes. In some examples, this disclosure describes techniques for storing files larger than a maximum file size allowed for File Allocation Table (FAT) file systems to a volume formatted according to a FAT file system. This disclosure describes techniques for handling calls associated with large files. In this manner, the techniques described here may support larger file sizes while being backwards compatible.

  • SYSTEMS AND METHODS FOR PERFORMING DATA OBJECT RENAMING OPERATIONS
    Publication number: 20180011872
    Abstract: This disclosure describes techniques performing data object renaming operations. This disclosure describes techniques for performing data object renaming operations in a manner that may reduce file system corruption and data loss. The techniques described herein may include selectively journaling particular types of renaming operations. Selectively journaling particular types of renaming operations may mitigate potential data loss and file system corruption.

  • READING OR WRITING TO MEMORY
    Publication number: 20110320718
    Abstract: To increase the efficiency of a running application, it is determined whether using a cache or directly a storage is more efficient block size-specifically; and the determined memory type is used for a data stream having a corresponding block size.
